Air Navigation for CHPL course covers General Navigation Radio Aids, Instrumentation, Mass balance and performance. General navigationmeans the process of planning, coordination and controlling the movement of aircraft from one place to another without getting lost, not breaking the laws applying to aircraft. Air navigation is different than ground navigation in terms of Speed, time and height. Radio Aids is the second topic that cover various navigation and landing aids based on electromagnetic waves. Third topic is the instrumentation which covers Pressure instruments, Gyro instruments, Flight Management System, Inertial Navigation System, Inertial Reference System etc. Rest topics cover fuel calculations, Payload calculations, calculations of distances required for take-off and landings of aircraft etc. Duration required for Air Navigation is normally 30 days.
