monitoring aircraft in-flight, and ensuring compliance with safety regulations.

• Which document provides legal authority for a flight to operate?
• Aircraft logbook 1 / 4

• Pilot license
• Flight release
• Maintenance record

Rationale: The flight release issued by a dispatcher or pilot serves as legal

authorization to conduct the flight.

• When calculating takeoff performance, what environmental factor is

most critical?

• Altitude and runway condition
• Air traffic volume
• Temperature and pressure altitude
• Airport lighting

Rationale: Temperature and pressure altitude significantly affect engine

performance and required runway length.

• Which regulation governs flight dispatch operations in the U.S.?
• FAA Part 91
• FAA Part 121
• FAA Part 135 and 121 (operations and dispatch)
• ICAO Annex 6 only

• Wind does not affect fuel
• Wind direction affects only takeoff

Rationale: Headwinds slow the aircraft and increase fuel consumption, while

tailwinds reduce it.

• What is the primary purpose of NOTAMs?
• Weather updates
• Informing pilots and dispatchers of temporary changes or hazards

• Passenger announcements

Rationale: NOTAMs alert flight crews to temporary conditions, like runway

closures or airspace restrictions.

• What is the primary function of a load manifest?
• Flight crew roster
• Aircraft maintenance log
• Listing passengers, cargo, and weight distribution

Rationale: The load manifest ensures proper weight and balance for safe

operations.

• When is an en-route weather update required?
