What are typical items included in the ATR pre-start checklist?

• A. External power or APU availability, doors/door area secure, flight controls free, flight deck instrument checks, systems data set, and takeoff data set.
• B. Engine start sequence.
• C. In-flight fuel management.
• D. Flight plan filing.

Answer: (A)

Preparing the aircraft for engine start means confirming that everything needed for a safe start is in place and correctly configured. The items listed in this set cover those essential readiness steps: having external power or an available APU ensures the cockpit and systems can operate without relying on the engines; securing all doors and the door area prevents movement or accidental openings during start and taxi; making sure flight controls are free ensures there are no obstructions or binding that could affect control authority once the engines are started; checking the flight deck instruments confirms that displays, indicators, and avionics are functioning so you can monitor and control the aircraft properly; loading the systems data sets ensures the systems are configured correctly for the current flight, and loading the takeoff data set provides the correct performance parameters (such as speeds, weights, and thrust settings) needed for a safe takeoff. Engine start sequence belongs to the actual start procedures that follow the pre-start steps, not part of the pre-start check. In-flight fuel management and flight plan filing relate to operations during flight or pre-flight planning, not the pre-start readiness of the aircraft itself.
