Certified Flight Instructor (CFI) Practice Exam

What speed should the pilot achieve to ensure safe takeoff after an engine failure occurs?

1. V1

2. Vx

3. Vr

4. V2

The correct answer is: V2

The correct answer is V2, which is the minimum safe speed that a pilot must achieve during takeoff after an engine failure. V2 is critical for ensuring that the aircraft can climb safely and gain the necessary altitude, even with one engine out. This speed provides the margin needed to maintain control and clear any obstacles in the aircraft's flight path. It is especially important in multi-engine aircraft where engine-out performance is a key consideration in flight safety. While V1 is the decision speed at which a pilot must decide whether to continue the takeoff or abort it, it does not guarantee the aircraft's ability to climb after an engine failure. Vx is the best angle-of-climb speed, used for maximizing altitude gain over distance, but it may not be achievable or safe immediately after an engine failure. Vr is the rotation speed, the speed at which the pilot begins to lift the nose of the aircraft off the runway; however, it does not consider the specific requirements of maintaining control and climb performance in the event of an emergency like an engine failure.
