Revision HistoryDate Who ID Notes
13 Jun 2011 1st Lt Todd GamberCAPID 443746
v1 -Created Day 3 presentation-Added advanced Becker/DF features-Added advanced search patterns-Added appendix with PC Trainer setup, MFD Setup, and Optional MFD Overlays
10 Sep 2012 Capt Todd GamberCAPID 443746
v2 -Added instructions to start the PC Trainer in dual-screen mode (since the single-screen PFD and MFD modes are buggy)-Removed slide which talks about PFD mode and MFD mode-Added more specific instructions on simulating movement on the PC Trainer
Thanks to Capt Jeremy Sing for recommended changes.

signal3 – go to 121.5 mode4 – frequency range
COSPAT-SARSAT Scanning Mode
• Will scan 406 all frequencies within 400ms
Interpreting the box
1 – relative bearing value
2 – spread3 – receiving level4 – squelch level5 – last signal
Advanced Features
1 – frequency selection
4 – clear averaging value (3 seconds)
6 – repeat last good signal
Setting the Squelch
Correctly set squelch for NO SIGNAL being received
Incorrectly set squelch (listening to noise)
Setting the Squelch
Automatic squelch set by system, can be manually overridden, to go back to automatic set squelch to 0% or above 60%
Setting the Squelch
Squelch controlled by the system (cannot be overridden)
Flight Plan
• A sequence of waypoints, connected with lines.
• Lines = legs• Active leg is magenta• Planned leg is white• See Flight Plan with the
FPL button• Shown on MFD and PFD
Creating a Flight Plan
1. FPL button2. Push FMS knob (cursor)3. Outer FMS knob to highlight
a blank space4. Inner FMS knob to change5. ENT button to add waypoint
Amending a Flight Plan1. Push FMS knob (cursor)2. Outer FMS knob to
highlight a waypointTo insert a waypoint:3. Inner FMS knob to enter
name of waypoint4. ENT button to confirm5. Inserts above highlighted
pointTo remove a waypoint:6. CLR to remove7. ENT button to confirm
Storing a Flight Plan
1. Go to FPL page 12. Ensure cursor is
deactivated3. Push MENU4. Outer FMS knob to
highlight “Store…”5. ENT button to confirm
Activating a Stored Flight Plan
• Go to second page of FPL page group
• Push FMS knob• Outer FMS knob to
highlight desired plan• ACTIVE soft key• ENT to confirm
Advanced SAR Patterns
• Sector• Expanding Square• Route• Creeping Line
Sector Search1. Activate a flight plan
consisting of at least the start point
2. FPL button3. FMS knob: Push to
activate cursor4. FMS knob: Highlight entry
point (grid corner)5. MENU button6. FMS knob: Search and
Rescue7. ENT button(continued on next slide)
Sector Search (cont’d)8. FMS knob:
– Pattern: Sector– Initial DTK: Mag heading
on first leg (you correct for variation)
– Initial Turn: Left/Right– Leg Length: Your Choice
9. FMS knob: ACTIVATE SAR
10. ENT button*NOTE: Will go direct-to
entry point
Expanding Square Search1. Activate a flight plan
consisting of at least the start point
2. FPL button3. FMS knob: Push to
activate cursor4. FMS knob: Highlight entry
point (grid corner)5. MENU button6. FMS knob: Search and
Rescue7. ENT button(continued on next slide)
Expanding Square Search (cont’d)8. FMS knob:
– Pattern: Exp Sqr– Initial DTK: Mag heading
on first leg (you correct for variation)
– Initial Turn: Left/Right– Number of legs: Your
choice9. FMS knob: ACTIVATE
SAR10. ENT button*NOTE: Will go direct-to
entry point
Route Search*1. Ensure your data bar fields
contain XTK (Cross-track)2. Activate a flight plan
consisting of at least the start and end points of the route.
3. Fly down one side of the route at 1.0NM XTK, then down the other side at 1.0NM XTK
* Can also be performed using a the “Parallel Track” feature on a leg of the flight plan
Creeping Line SearchThis is really just a parallel track
pattern with different dimensions
1. Find DTK between start point and end point by entering that leg in the flight plan
2. FMS knob: Highlight beginning waypoint
3. MENU button4. FMS knob: Search and
Rescue5. ENT button(continued on next slide)
DTK = 245
Creeping Line Search6. FMS knob:
– Pattern: Parllel– Initial DTK: 90 degrees from
the DTK between waypoints– Initial Turn: Left or Right
depending on whether you added or subtracted 90 degrees
– Leg Length: 5.0NM– Spacing: 2.0NM– Number of legs: A few
dozen7. FMS knob: ACTIVATE SAR8. ENT button
DTK = 245Initial DTK = 254-90Initial DTK = 155Turns = Right turns, because we subtracted 90 degrees from the DTK
