Navigation and Flight Planning NavLogs!
Charles Lindbergh & Spirit of St Louis Roosevelt Field, Long Island, NY – Paris, France First flight between New York and Paris
Types of Navigation Pilotage – Reference to visible landmarks Dead Reckoning – Computations based on time, distance and speed Radio/Area Navigation – Reference to land-based radio stations or GPS satellites
Terminology Navlog – Navigation Log Course – intended path of travel Magnetic Variation – Difference between True and Magnetic North Isogonic Line – Visual depiction of magnetic variation on the map Magnetic Deviation – Compass error due to installation and aircraft interference True Course – First line drawn on the map True Heading – True course corrected for wind Magnetic Course – True heading corrected for magnetic variation Compass Heading – Magnetic course corrected for magnetic deviation (what you read on the compass to fly your intended route)

Variation: Differences in magnetic field between True North and Magnetic North. Deviation: Compass errors due to installation in aircraft True Course (TC): First line on the map…this line True Heading (TH): TC corrected for wind Magnetic Heading (MH): TH corrected for variation Compass Heading (CH): MH corrected for deviation
