Pilot_logbook
A pilot logbook is a record of a pilot's flying hours. It contains every flight a pilot has flown, including flight time, number of landings, and types of instrument approaches made. Pilots also log simulator time, as it counts towards training.[1]: FCL.630.H [2]
In most countries, pilots are required to maintain a logbook, per their government's aviation regulations. The primary purpose is to show that certain requirements have been met for a certificate or rating, and for currency purposes.
Time logged is block time, which includes time spent taxiing, not just time in the air.
