General InformationA preflight briefing may be obtained from Dispatch or a Flight Service Station by telephone, radio, personal visit or online. The briefing should consist of weather, airport, enroute NAVAID information and NOTAMS.
Normally, the trip is planned and the weight and balance computations are determined first. However, when conditions at the departure airport are near the maximum operating limits of the aircraft, take off performance data should be determined first. This prevents planning a trip and then discovering that take off is impossible with the planned passenger and fuel load.
The performance tables require that the planned altitude and approximate aircraft weight be known. Aircraft weight decreases as fuel is consumed and can be estimated by scheduling 1,200 lbs for the first hour, 1,000 lbs for the second, and 800 lbs for each subsequent hour.
In real world situations, the estimated fuel required must be modified for known delays (e.g., weather, diversions, air traffic flow).
If fuel conservation is more important than time to destination, consult the specific range vs. cruise wind tables in the Citation II Operating Manual for long range cruise information.
In most cases UV Flight Planner creates a flight plan based on 98% cruise, which is a balance between long range cruise and maximum cruise. For the exercises contained here, this chapter uses the Citation II maximum thrust setting of 104% N1 for the cruise legs to the primary and alternate destinations.

Weight and BalancePrecise weight and balance computations are essential elements of flight planning. Accuracy of these computations is required to ensure a safe flight. This section reviews the procedures for computing weight and balance data.
Aircraft Services uses a computer generated excel spreadsheet, W+B. The data is entered by the pilot or a dispatcher.
1. Enter departure and destination identifiers.
2. Type in the last 3 letters of the aircraft registration. This will define the basic weight data to be used on item 4.
3. Call sign corresponding to registration (item 2).
4. Basic dry weight data for airplane used.
5. Occupants: indicate actual occupant weight for each seat used for the flight.
6. Baggage: indicate actual baggage loading in each area.
7. Payload: sum of occupants and baggage.
8. Zero Fuel Weight : calculated automatically.
9. Ramp Fuel: Fuel load prior to engine start.
10. Ramp weight: calculated automatically.
11. Take Off Fuel: Ramp Fuel less 200 LBS.
12. Take Off Weight: calculated automatically.
13. Fuel burn for the flight.
14. Fuel remaining at landing.
15. Landing weight: calculated automatically.
16. Maximum weight limitations for these items.
17. Journey log entries: used to fill log book.
18. Pilot in command signature.
Note 1: If any weight or CG is exceeded a message will indicate the problem. Ex:”too much fuel” or “overweight”

Summary Flight PlanningThe sample begins with a Summary Flight Planning estimate of trip time and fuel consumption. Using this estimate, the approximate time, distance and fuel can be computed.
Determine estimated trip time and fuel consumption, including the alternate leg, by using the applicable Maximum Cruise Thrust chart (Figure 16-1).
For this example, use the chart for 104% N1 at 37,000 feet.
1. Enter the chart from the bottom left at the correct cruise wind (50 kts Headwind).
2. Move to the right to the correct total stage length arc, including alternate.
For this example, the distance is 680 NM (600 NM to destination plus 80 NM to alternate).
3. Move up to the time and fuel angled reference lines to an approximate take off weight.
For conservatism, use the 14,100 lbs reference lines on each pair of lines.
4. Move to the left from the fuel line to the edge of the chart to determine the fuel requirement (2,750 lbs).
5. Move to the right from the time line to the edge of the chart to determine the duration of the flight (2:33), which includes a diversion to the alternate.
6. Add the minimum landing fuel quantity of 600 LBS to the trip fuel for the fuel requirement. This fuel is available to use, if required.
Adding the Aircraft Services minimum landing fuel quantity (Table16-1) to the 2,750 lbs estimate derives the fuel requirement, or 3,350 lbs. The take off and approach fuel quantities need not be considered because they are included in the manufacturer’s chart.
Take Off 200 LBS Approach 200 LBS Minimum Landing 600 LBS (for flight planning)

Detailed Flight PlanningWhenever a computerized flight plan is not available, proper detailed planning is required to ensure safe performance. This section reviews the computations necessary to plan a trip.
After establishing the approximate fuel and time requirements for the trip, determine the approximate gross take off weight.
In this example, there are no unusual conditions (e.g., distance, elevation, climb gradient requirements, airport ambient temperatures, runway lengths). A take off weight of 14,100 lbs is desired; the additional weight above the basic empty weight, payload, and minimum fuel requirement is composed of tankered fuel.
Climb Time, Distance, and FuelUse the appropriate Cruise Climb table (Figure 16-2) to determine time, distance, and fuel required for the climb to cruising altitude. To determine the effect of winds aloft on climb distance, see the Wind Effect on Climb Distance table at the bottom and use the 60/40 rule; that is, apply 60% of the cruise wind to determine climb distance.
1. Enter the appropriate altitude block (37,000 feet) at the correct ISA value (ISA).
2. Look up for the appropriate take off weight column (14,100 lbs). Read the necessary time, distance, fuel requirement, and rate of climb, (35 minutes, 169 NM, 797 lbs, and 178 fpm, respectively).
3. To determine the effect of wind on climb distance, perform the following.
a. Enter the Wind Effect on Climb Distance table as closely as possible to the previously determined climb time (30 minutes).
b. Move right to the appropriate wind column. Interpolate as required.
Sixty percent of the cruise headwind is 30 kts; the inter-polated correction factor is 15 NM.
3. Subtract the headwind correction factor (15 NM) from the previously determined climb distance (169 NM).
The corrected climb distance is 154 NM.

Descent Time, Distance and FuelUse the appropriate Normal Descent table (Figure 16-3) to determine time, distance, and fuel in descent. Again, apply the 60/40 rule; that is, apply 40% of the cruise wind to determine descent distance.
1. Enter the table from the left at the appropriate altitude (37,000 feet).
2. Move to the right to obtain the time and fuel used in the descent (18.5 minutes and 185 lbs, respectively).
3. Continue right to adjust for wind component.
Interpolation for 20 kts (i.e., 40% of the cruise headwind of 50 kts) yields 84.8 NM. Round this up to 85 NM.

Cruise DistanceDetermine the distance covered at cruising altitude by subtracting the climb and descent distances from the total distance.
The climb distance previously determined is 154 NM. The descent distance previously determined is 85 NM. Thus, the cruise distance is 361 NM (600 minus (154 plus 85) equals 361).
Cruise Thrust and Fuel ConsumptionIf Long Range cruise is preferred to higher true airspeed, use the appropriate Specific Range vs. Cruise Wind chart (Figure 16-4).
Assume for a moment that thrust is not 104% N1, but that you wish to determine thrust for long range cruise.
1. Enter the table at the top of the figure from the left at the planned altitude (37,000 feet).
2. Move right to the forecast cruise wind column (50 kts headwind) and read the thrust setting (97.6%).
3. To determine specific fuel consumption at the long range cruise thrust setting, perform the following.
a. Enter the graph at the bottom of the figure from the bottom at the headwind component (50 kts headwind).
b. Follow the line up to its intersection with the desired cruise altitude (37,000 feet).
c. Move to the left to the edge of the chart to read the specific fuel consumption.
The specific fuel consumption is 35 NM/lbs.
NOTE:
T - (L + D) = C

True Airspeed and Fuel FlowUse the Normal Cruise table (Figure16-5) to determine the cruise true airspeed and fuel flow. Use the highest listed value closest to the weight of the aircraft at the start of the cruise segment.
1. Enter the table from the left with the appropriate weight, fan RPM, and OAT.
Use 14,000 lbs (14,100 minus 797 equals 13,303 lbs, rounded up to 14,000) for weight. Recall that the temperature is ISA and the cruise thrust is 104% N1. In this example, use an OAT value of -56˚C.
2. Move right and interpolate the figures for fuel flow and true airspeed. The fuel flow is 979 lbs/hr, and the true airspeed is 359 kts.
Cruise GroundspeedDetermine the groundspeed by adding to or subtracting the forecast cruise wind from the true airspeed.
Because a 50 knot headwind is forecast, the groundspeed is 309 kts.
Time at CruiseFind the time at cruise by dividing cruise distance by the computed groundspeed.
The cruise distance was previously determined to be 361 NM, and the groundspeed is 309. Thus, the time at cruise is 1.16 hours (1 hour, 9.6 minutes; round this up to 1 hour, 10 minutes).

Cruise FuelThe amount of fuel required for cruise is the sum of the fuel flow rates determined for each hour or part of an hour at cruise. Use the Cruise table (Figure 16-6).
Time at cruise was computed previously as 1.16 hours (1 hour, 10 minutes). Fuel flow for the first hour is 979 lbs/hr at an aircraft weight of 13,303 lbs (rounded up to 14,000 lbs).
The cruising weight for the second hour is obtained by subtracting the fuel used during the first hour from the first hour airplane weight.
Thus, an aircraft weight of 14,000 lbs minus 979 lbs fuel is 13,021 lbs.
To determine second hour fuel consumption, perform the following.
1. Enter the table at the weight closest to the second hour aircraft weight (13,000 lbs).
2. Move right to read fuel flow (983 lbs/hr), fan RPM (104.0), and temperature (-56˚C).
3. Calculate second hour fuel consumption.
When 0.2 hour (i.e., 10 minutes) is multiplied by 983, the result is 196.6 lbs (rounded to 197).
4. Add the fuel values to determine fuel required at cruise.
Adding the 979 lbs for the first hour to the 197 lbs for the final 10 minutes yields a total cruise fuel consumption of 1,176 lbs.
Total Time EnrouteThe total time enroute is determined by adding the times for climb, cruise, and descent.
Climb 0:35.0 hours : minutes
Cruise 1:10.0
Descent 0:08.5
TOTAL 2:03.5 (rounded to 2:04)
Fuel Required EnrouteThe total fuel required enroute is the sum of the fuel needed for climb, cruise, and descent.
Climb 797 lbs
Cruise 1,176
Descent 185
TOTAL 2,158

Alternate Leg ComputationsUse the appropriate Normal Descent, Cruise Climb, and 17,000 Feet Cruise tables to determine the fuel required to the alternate airport.
Assume a zero headwind.
Descent distance is the key to establishing the altitude for cruise and for beginning the descent to the alternate. Compute the climb and cruise segments of the alternate leg after determining the altitude from which the descent begins.
When an alternate is 100 NM or less from the primary destination, use a 60/40 ratio to determine climb and descent segments enroute to the alternate. That is, 40% of the distance to the alternate is in the descent.
The fuel required to the alternate airport is the sum of the fuel requirements for the climb, cruise, and descent segments enroute to the alternate.
First, refer to the Normal Descent table (Figure 16-7).
1. Using the 60/40 ratio, enter the table in the appropriate wind column (zero). Read down to the number closest to 40% of the distance to the alternate. Interpolate as required.
Because the distance to the alternate is 80 NM, 40% of this number is 32 NM.
2. Move to the left to the edge of the table to determine the altitude at which to begin the descent, the descent time, and the descent fuel.
Because 32 does not appear on the chart and an odd altitude is appropriate for the leg, 34 NM and 17,000 feet are chosen. The time required is 8.5 minutes, and the fuel used is 85 lbs.
Next, use the Cruise Climb table (Figure 16-8) to determine the time, distance, and fuel required for the climb to the alternate leg cruise altitude (17,000 feet).
1. Enter the table at the appropriate weight for the alternate leg altitude (17,000 feet) and move down to the data block opposite the correct ISA value (ISA).
Because the 14,100 lbs take off weight minus the 2,158 lbs enroute fuel weight is 11,942 lbs, use the 12,000 lbs column.
2. Read the data block.
The figures for the alternate climb are 6 minutes, 22 NM, and 201 lbs of fuel.

where:

G = Groundspeed
T = Time At Cruise
C G =T
Alternate Leg Computations (continued)Next, compute the cruise distance to the alternate as you did for the destination cruise segment: subtract the sum of climb distance and descent distance from the total distance.
Cruise distance equals 80 NM minus (22 NM plus 32 NM), or 26 NM.
Now, use the appropriate Cruise table (17,000 feet) (Figure 16-9) to compute cruise time and fuel to the alternate.
1. Enter the table from the left with the appropriate aircraft weight (12,000 lbs) and fan speed (94.9% N1 RPM, the maximum cruise thrust).
2. Read the true airspeed (333 KTAS).
3. Compute time at cruise by dividing the cruise distance by the groundspeed.
The 26 NM cruise distance divided by 333 equals a cruise time of 0.08 hrs, or 5 minutes.
4. Read the fuel flow (1,539 lbs/hr).
5. Compute fuel consumption for the cruise time.
The cruise time is 0.08 hours, thus 0.08 times 1,539 is 124 lbs.
6. Add fuel and time values for all alternate segments.

Total FuelThe Operations Manual (O.M.) requires the following fuel to be carried on the Citation aircraft:
• fuel to fly and execute an approach to the primary destination, then to the alternate, execute a missed approach and fly to the alternate.
• fuel for 15 minutes at holding speed at 1,500 feet above the alternate under standard temperature conditions.
• execute and approach to the alternate.
• minimum landing fuel (600 lbs) as required by the O.M. This is for flight planning purposes and can be used, if required.
• contingency fuel based on consideration of the factors listed below.
Contingency fuel considers the following:
• forecast meteorological conditions.
• anticipated routing and traffic delays.
• the possibility of pressurization loss or an engine failure enroute.
• any other condition that could delay landing.
Taxi and take off fuel is normally planned at 200 lbs. Minimum landing fuel is planned at 600 lbs; this amount also satisfies holding requirements. Approach fuel normally is planned at 200 lbs.
For this example, the following figures apply.
Segment Fuel (lbs)
Taxi/Take Off 200
Primary Destination 2,158
Approach 200
Alternate Destination 410
Contingency 200
Minimum Landing Fuel 600
MINIMUM FUEL REQUIRED 3,768
In this case, because of the traffic delays expected at the destination, 200 lbs contingency fuel has been decided upon.

Take Off, Landingand Climb PerformanceTo understand performance, it is necessary to be thoroughly familiar with the terms used in describing an aircraft’s performance data. This section reviews the definitions and terms used while determining performance data, and presents computations required to fill out the TOLD card. In addition, you are taken through the steps necessary for determining take off and landing data and V speeds.
DefinitionsBefore performance can be discussed, certain terms must be clearly understood. To that end, the following definitions are provided.
Accelerate-stop distance – The distance required to accelerate to V1 and reject the take off due to a failed engine (at V1).
Altitude – All altitudes used in this textbook are pressure altitudes unless otherwise stated.
Climb gradient – The ratio of the change in height during a portion of a climb to the horizontal distance transversed in the same time interval.
Engine out accelerate-go distance – On a take off during which an engine fails at V1 and the take off is continued, the horizontal distance from brake release to the point at which the aircraft attains a height of 35 feet above the runway surface.
Gross climb gradient – The climb gradient that the airplane can actually achieve with ideal conditions.
Landing distance – The distance from a point 50 feet above the runway surface to the point at which the aircraft would come to a full stop on the runway.
Net climb gradient – The gross climb gradient reduced by 0.8% during the take off phase and 1.1% during enroute. This conservatism is required by FAR 25 for terrain clearance determination to account for variables encountered in service.
OAT – Outside Air Temperature or Ambient Air Temperature. The free air static temperature, obtained either from ground meteorological sources or from inflight temperature indications and adjusted for instrument error and compressibility effects.

RAT – Ram Air Temperature. The indicated outside air temperature as read from the pilot’s panel.
Reference zero – The point in the take off flight path at which the aircraft is 35 feet above the take off surface and at the end of the take off distance required.
Take Off field length – The take off field length given for each combination of gross weight, ambient temperature, altitude, wind, and runway gradients is the greatest of the following:
• 115% of the two-engine horizontal take off distance from start to a height of 35 feet above runway surface
• accelerate-stop distance
• engine-out accelerate-go distance.
No specific identification is made on the charts as to which of these distances governs a specific case. In all cases considered by the charts, the field length is governed by either the second or the third condition because the Citation two-engine take off distance is always shorter.
TOCA - Is defined as the ”take off obstacle clearance altitude” or as the altitude, expressed in feet above sea level, at which the aircraft will clear an obstacle by 35 feet., and is the altitude at which the aircraft is accelerated in third segment. TOCA will be included in all take off briefings. TOCA will normally not be less than 1500 feet.
VAPP – The landing approach airspeed (1.3 VS1) with T.O. & APPR flaps and landing gear up.
VENR– Single engine enroute climb speed. VENR is also the best rate of climb speed single engine and may be used as the single engine driftdown speed.
Visible Moisture - Visible moisture includes, but is not limited to the following conditions: fog or clouds with visibility less than 1 mile, wet snow and rain.
VR – Rotation speed. The speed at which rotation is initiated during take off to attain the V2 climb speed at or before a height of 35 feet above runway surface is reached.
VREF – The airspeed equal to the landing 50-foot point speed (1.3 VSO) with full flaps and landing gear extended. VREF is adjusted for wind gusts by adding the gust to a maximum of 10 kts.

V1 – Critical engine failure recognition speed. The speed at which the pilot observes an engine failure or other condition for which a decision to stop or continue the take off to 35 feet does not exceed the scheduled take off field length if recognition occurs at V1 (accelerate-go). The distance to bring the aircraft to a full stop (accelerate-stop) does not exceed the scheduled take off field length if the brakes are applied at V1.
V2 – Take off safety speed. This climb speed is the actual speed at 35 feet above the runway surface as demonstrated in flight during take off with one engine inoperative.
VT – Target speed. A general speed for flight which is pilot selectable on the primary flight display, this speed is VENR on take off and VREF +20 kts for approach and landing.
W.A.T. – Weight, Altitude, Temperature. This is the weight limit required to meet the FAR 25 requirement of a Positive climb in segment #1 and 2.4 % gradient in segment #2 up to 1500 feet above the take off surface
Wind – The wind velocities recorded as variables on the charts of this section are to be understood as the headwind or tailwind components of the actual winds at 30 feet above the runway surface (tower winds).

Takeoff Airport Information ATISAirport information is obtained from the standard sources. The UV Flight Plan has space to write the ATIS information.
In this case, use the trip planning data provided (pg 16.7) and assume a forecast runway wind of 340/12.
Wind Component at Take OffUse the Cross Wind Component chart (Figure 16-10) to determine the wind component at take off.
1. First, determine the angle between the runway heading and the forecast wind direction.
With a runway heading of 310˚ and a forecast wind from 340˚, the resultant angle is 30˚.
2. Plot the point at which the forecast wind velocity (12 kts) intersects the angular difference between the runway heading and the forecast wind direction (30˚).
3. Move left to the edge of the chart to obtain the headwind/tailwind component (10 kts).
Although the headwind component lies between 10 and 11 kts, conservatism dictates the use of the lower number.
4. Move down from the intersection to the bottom of the chart to obtain the crosswind component (6 kts).
5. Copy this information to the ATIS portion of the universal flight plan.
Take off weight is limited by
the most restrictive of:
• maxcertifiedtakeoff
weight (14, 100 LBS)
• maxtakeoffweight
permitted by climb
requirements (WAT)
• takeofffieldlength.

T/O PWR (1)Consult the Take Off/Go Around Thrust N1 % RPM (QRH or AFM) to determine the correct Take Off thrust setting (See opposite page)
1. Enter the chart from the left at the ambient temperature (15˚C) and move right to the appropriate pressure altitude column (1000 feet).
2. Use the value for anti-ice off (99.3%).
3. Interpolate as required.
Flap (2)Indicate flap setting to be used on take off. Flaps 15° is the preferred setting unless flaps 0° is required for performance (climb) considerations.
MCT Power (3)Use the Maximum Continuous Thrust Setting chart (QRH or AFM) to determine the single-engine maximum continuous thrust setting. This is our initial climb thrust.
1. Enter the chart from the left at the pressure altitude (2000 feet) and move right to the appropriate anti-ice/on or off line for the temperature to be used.
2. Interpolate to find the initial “climb” thrust setting. In this sample, at 2000 feet Temp of +10, No Anti-Ice use 98.8% N1
This is the initial climb power set after take off. It is actually MCT and readily available in case of an engine failure. After the SID and/or noise abatement (usually 3000 feet AAE), use the normal climb power schedule (located on control column or in the QRH).
Normal Climb Power
Use normal climb power setting.(control column, QRH or AFM). Proceed in a similar way as for the MCT Power. In this case using our trip planning data: 5000 feet/+10˚C No Anti-Ice=98.9% N1 (Figure 16-11).

Performance for Contaminated RunwaysTAKE OFF
Use the Flow Chart to identify changes in take off performance when operating on contaminated runways. Observe the following AFM notes.
1. Takeoffs should not be attempted in any precipitation depth greater than presented on the charts. Do not exceed the contaminants, altitude, temperature, gross weight, wind limits at the bottom of the charts.
Single Engine Take Off ProfileFlaps 15˚The data presented in QRH or AFM Supplement 37 contains information to determine the net climb gradient in the second segment.

Obstacle Clearance (7)The second segment climb gradient is calculated to determine if we can clear obstacles on the departure path.
CAP departures require a minimum climb gradient of 200 Feet/NM. This equates to a 3.3% climb gradient.
The tables in the QRH or AFM Supplement 37 provide quick reference for the second segment climb gradient calculation. It includes tables for converting FT/NM to percent (%) climb gradient and second segment take off net climb gradient for a flaps 15˚ or flap 0˚.
1.Convert FT/NM to % climb gradient to determine the required climb gradient from the SID chart.
2.Enter the table for the proper flap setting (In this case flap 15˚).
3.Add 1500 feet, which is our TOCA altitude, to the departure aerodrome pressure altitude. In our sample the aerodrome pressure altitude is 1,000 feet +1,500 feet=2,500 feet
4.Use the 3000 feet altitude column on the left.
5.Take the temperature at that altitude (use 3,000 feet) (15˚-5˚=10˚)
6.Using the proper weight and wind column choose the gradient here no wind = 4.6%
7.Interpolate as required.
8.When anti-ice is used reduce that number by 3%. (note on bottom of the net climb gradient page)

Net Take Off Flight Path ConsiderationsAll take offs require net takeoff flight path and obstacle clearance calculations however, we have an Operations Specification (OPS SPEC) that allows us to takeoff visually by employing Turbo-jet on Demand Operations. The pilot may opt to depart under the conditions listed in CARS 724.47 (Turbo-jet on demand operations) (on the following pages), which waives the obstacle clearance requirements however, extreme caution should be exercised in the use of this waiver in the presence of obstacles. Our intention is to use this for “see to takeoff” conditions.
When calculating net take off flight, path, many variables are involved that must be approached with common sense and good airmanship.
• Where no obstacles exist and a standard climb gradient is permissible (200 feet/nm).
• The pilot may determine that the prevailing weather allows obstacles to be avoided. If so, the take off may be made. It must be noted that visual maneuvering is not permitted if it requires the aircraft being turned towards another obstacle. Where a climb gradient greater than 200 feet/nm is required, or an obstacle exists, the pilot must refer to the second segment net climb gradient chart.
• All instrument flight condition take offs must achieve a climb gradient of at least 200 feet/nm to remain above the obstacle clearance surface. However, some airport departure instructions will specify a higher climb gradient to clear known obstacles, and in other cases, the pilot must survey the planned flight path to determine the precise location of an obstacle that may affect the departure.
TOCA is defined as the “Take Off Obstacle Clearance Altitude” or as the altitude, expressed in feet above sea level, at which the aircraft will clear an obstacle by 35 feet, and is the altitude at which the aircraft is accelerated in third segment to retract flaps, and accelerate to single engine climb speed (Venr). TOCA will be included in all take off briefings and will normally not be less than 1500 feet.
To eliminate complex and error-prone calculations, a selection of options has been developed for ease of flight planning in the form of a logic flow chart (Opposite page and QRH).

Turbo-Jet On Demand Operations The standard for conducting a take off during an on demand operation using a turbo-jet powered aeroplane without demonstrating that the Net Take Off Flight Path provides obstacle clearance is as follows:
a) the air operator shall comply with all take off weight limitations set out in the aircraft flight manual;
b) the airport elevation shall not exceed 4000 feet ASL;c) the Take Off Run Available (TORA) shall be greater than or equal to
1.5 times the Take Off Distance calculated on the TOLD card; andd) ceiling and visibility shall be at or above the landing minima for the
runway in use.
Pilots are reminded that in some cases, obstacle clearance or climb gradient performance may be marginal or inadequate for the planned take off. If this occurs, the pilot should consider available options, such as reducing take off weight, delaying until temperatures are cooler, or an alternate flap configuration. Changing any or all of these may result in the required performance being met, thus permitting the flight to depart. When considering an alternate flap configuration for take off, it must be remembered that a zero flap take off requires a longer take off run, but gives better 2nd segment climb performance. Conversely, a 15° flap take off permits a shorter take off run, but results in a degraded 2nd segment climb performance.

Take Off Performance Simplified CriteriaA simplified criteria is provided which is intended to cover the majority of situations where runway length is appreciably longer than required for this airplane. The other tabulated data gives more exact performance criteria through a range of conditions which include all but the most extreme cases.
The majority of take off situations results in field length margins that permit using a single set of values for speeds and power settings for take off. If the following conditions are met, the simplified procedures may be used.
1. No obstacle in flight path. 2. Anti-Ice systems off. 3. Take Off and approach flaps (15°). 4. Take Off field length available = 5000 feet or longer. 5. No tail wind. 6. No runway gradient. 7. No runway contamination

Crosswind Limits for CRFI ReadingsThis chart provides information for calculating headwind and crosswind components and the vertical lines indicate the recommended maximum crosswind component for reported CRFI.
The wind is 40° off the runway heading and produces a headwind component of 15 KIAS and a crosswind component of 13 KIAS. The recommended minimum CRFI for a 13 KIAS crosswind component is .36. A take off or landing with a CRFI of .36 or less may result in uncontrollable drifting and yawing.

Listen to the ATIS and write on the TOLD card, in the space provided.
Crosswind Component at DestinationUse the Crosswind Component chart (QRH) to determine the wind component.
1. Determine the angle between the runway heading and the forecast wind direction.
With a runway heading of 130˚ and a forecast wind from 128˚, the resultant angle is 2˚.
2. Plot the point at which the forecast wind velocity (12 kts) intersects the difference between the runway heading and the forecast wind direction (2˚).
3. Move left to the edge of the chart to obtain the headwind/tailwind component (12 kts).
4. Move down to the bottom of the chart from the intersection to obtain the crosswind component.
The crosswind component is less than 1 kt; therefore, use 0 kts.

Maximum Allowable Landing WeightUsing the Maximum Landing Weight Permitted by Climb Requirements or Brake Energy Limits table (Figure 16-13 from the AFM) to determine the maximum allowable landing weight under these conditions is not normally calculated. If conditions of high temperature at a high pressure altitude exist at the destination then, this would be a consideration.
1. Enter the appropriate altitude block (2,000 feet) from the left at the correct ambient temperature (15˚C).
2. Move to the right to the appropriate wind component block and, within the block, to the appropriate runway gradient column. Read the maximum landing weight permitted.
Because maximum landing weight under these conditions with a 10 kt headwind is the same as for a 20 kt headwind (i.e., 13, 500 lbs), the maximum landing weight permitted by climb requirements or brake energy is also 13,500 lbs for an 11 kt headwind.
The landing weight for this example, 13,037 lbs is well below the 13,500 lbs limit.
Landing weight is limited
by the most restrictive of:
• maxcertifiedlanding
weight (13,500 Ibs)
• maxlandingweight
permitted by climb
requirements or brake
energy limit
• landingdistance.

Landing Distance (14)Normally, calculating landing distance from the Citation Checklist, which uses a 4000 foot pressure altitude for reference, is sufficient. If landing runway length or runway surface conditions are a factor then the Landing Distance
-Feet tables from the QRH or AFM are to be used. Enter the tables at the pressure altitude of the landing airport and the aircraft landing weight to determine Landing Distance required by weight and ambient conditions.
1. Enter the block for the appropriate altitude (2,000 feet) and weight (13,000 lbs) column then from the left at the correct ambient temperature (15˚C).
2. Move to the right until the applicable distance is reached.
3. Read the landing distance. 2,500 feet in the grey block. Interpolate as required. Enter this information on the TOLD card.
4. To meet FAR 25, divide the runway length by 0.6. This is the required runway length. This is the factored distance in the white block. 2500 / 0.6 = 4.167 feet

Landing On Contaminated RunwaysThe published limiting maximum tailwind component is 10 kts; however, Cessna does not recommend landings on precipitation-covered runways with any tailwind component. Determine normal landing distances from QRH or AFM Section IV.
The corrections shown in the adverse runway conditions table apply only to unfactored distances (i.e., those not divided by 0.6).
The landing field required length is the greater of the factored landing distance or the unfactored distance corrected by the variables shown in (QRH or AFM).
