FAA Aircraft Dispatcher Practice Exam

What do V1, Vr, and V2 represent in aircraft operations?

1. Different stages of flight

2. Takeoff speed designations

3. Landing speed designations

4. Fuel management parameters

The correct answer is: Takeoff speed designations

V1, Vr, and V2 are critical speed designations during the takeoff phase of an aircraft's operation. V1 is known as the "decision speed." It marks the maximum speed at which a pilot can still initiate a safe abort of the takeoff if needed. Beyond this speed, the aircraft does not have enough runway left to stop safely, making it crucial for determining whether to continue with the takeoff or abort. Vr is the "rotation speed." This is the speed at which the pilot begins to lift the nose of the aircraft off the runway during takeoff. At this point, the aircraft is sufficiently fast to achieve the necessary aerodynamic lift. V2 is the "takeoff safety speed." This speed must be achieved by the time the aircraft reaches the end of the runway and is critical for the aircraft to safely climb away in case of an engine failure shortly after takeoff. It ensures that the aircraft can maintain controlled flight on one engine. Understanding these speeds is fundamental for safe aircraft operation during takeoff and is essential knowledge for anyone pursuing a career in aircraft dispatching or aviation in general.
