Which item is NOT part of recommended pre-operation checks?

• A. Verify lights, brakes, tires, hazard lights, fluids.
• B. Check the aircraft weight on board.
• C. Verify you have proper authorization and signage.
• D. Inspect tires for wear.

Answer: (B)

Focus on ensuring the vehicle and the driver are ready to operate safely on the airfield. Pre-operation checks for a ground vehicle include making sure the lights, brakes, tires, hazard lights, and fluid levels are all functioning and adequate, so the vehicle can be seen, controlled, and safely operated. Verifying you have proper authorization and clear signage is essential too, because it keeps you on the correct routes and in compliance with airfield rules. Inspecting tires for wear is part of the safety check to prevent failures during operation. Checking the aircraft weight on board, however, isn’t part of the ground-vehicle pre-operation checks; that’s a flight-specific concern tied to aircraft loading and performance, not to the readiness of the vehicle you’re driving on the field.
