Pilots record their flying time in a logbook for personal, professional and certification reasons. Logbooks are also kept for aircraft and engines.
× 91
a type of turbine engine which drives an aircraft propeller to produce thrust (as opposed to a jet engine, where the turbine exhaust provides thrust directly).
× 90
