Pilots track their hours using a Pilot Logbook, which in 2026 is almost exclusively digital. Apps like LogTen Pro or Wingman automatically sync with airline scheduling systems to import flight data, including "Block Time" (from gate to gate) and "Flight Time" (from takeoff to landing). These logbooks are legal documents required for license upgrades and insurance. Pilots must categorize hours into specific types: PIC (Pilot in Command), SIC (Second in Command), Night Time, and Instrument Time (flying by reference to instruments). Even as automation increases, every minute spent at the controls must be recorded to ensure compliance with fatigue regulations, which typically limit a commercial pilot to 1,000 flying hours in a rolling 365-day period.
