When first starting to move an aircraft while taxiing, it is important to

• A. test the brakes
• B. test the throttle
• C. check the altimeter
• D. adjust flaps

Answer: (A)

Testing the brakes before you begin taxiing ensures you can control your speed and stop safely on the ground. This check verifies the braking system responds properly and that you can rely on it to hold and slow the aircraft as soon as you start moving, which is essential for safe ground handling, especially on uneven surfaces or slopes. Altimeter is a preflight instrument for flight, not a on-ground safety check. Flaps affect lift and are configured for takeoff or landing, not for the initial movement on the ground. Power can be applied after you confirm brakes are functioning, so while throttle is important, it isn’t the immediate safety check needed when you first start to move.
