FAA Ground School Practice Test

Why is it important to maintain a constant glide speed in a single-engine airplane during an emergency approach?

1. To increase engine performance

2. To ensure better navigation

3. To enhance control in flight

4. To ensure accuracy in judgment of gliding distance and landing spot

The correct answer is: To ensure accuracy in judgment of gliding distance and landing spot

Maintaining a constant glide speed during an emergency approach in a single-engine airplane is crucial for ensuring accuracy in the judgment of gliding distance and the landing spot. When the aircraft is at a consistent glide speed, the pilot can better predict how far the airplane will travel before touching down, allowing for more precise calculations regarding the landing area. A steady glide speed helps the pilot to assess the descent rate and the effect of wind, terrain, and other factors that could influence where the aircraft ultimately lands. This consistency is vital in emergency situations, as the pilot may need to make quick decisions based on the available landing areas. Moreover, controlling the glide speed reduces the risk of stalling the aircraft, which becomes even more important when engine power is no longer available. Therefore, by keeping a stable glide speed, pilots maintain better situational awareness, allowing for effective navigation towards a safe landing spot.
