Ground Based Navigation BeaconsUsed to make flight routesVery high frequencyOmni directionalRange

Marker BeaconsUsed for precision airport approaches using ILS system Outer Marker : 4-7 miles from runwayMiddle marker: 0.5-0.8 miles from runwayInner marker: beginning of runway threshold

GPS NavigationSatellites guide aircrafts using waypointsGPS Waypoints use 5 letter names

ILSMost commonly used when landing in bad weatherInstrument Landing System

Flying EnrouteSwitch from departure controller to centerControls high altitude airspaces

SIDS and STARSSIDS = Standard Instrument DepartureAlso known as departure proceduresLocated on off rampsSTARS= Standard Terminal Arrival RoutesLocated on ramps

Non Towered AirportsTake offAir traffic control (ATC) gives clearance with a void timeLanding Remain under ATC control until landingCancel IFR once landed
