Why is maintaining a constant glide speed important when executing an emergency approach in a single-engine airplane?

1. To reduce engine strain

2. To maximize fuel efficiency

3. To decrease the airplane's rate of descent and increase gliding distance

4. To ensure passenger comfort

The correct answer is: To decrease the airplane's rate of descent and increase gliding distance

Maintaining a constant glide speed during an emergency approach in a single-engine airplane is crucial because it helps decrease the airplane's rate of descent and increase the distance the aircraft can glide. When a pilot establishes and holds an optimal glide speed, the aircraft achieves the best lift-to-drag ratio, allowing it to cover more horizontal distance while descending at a controlled and manageable rate. This optimized glide path is vital in emergency situations where the pilot may need to reach a suitable landing area, whether that be a runway or a designated off-airport site. By managing the descent rate effectively, the pilot enhances control over the aircraft and extends the available options for a safe landing, making it a key skill in emergency aviation operations. Maintaining constant glide speed is not primarily aimed at reducing engine strain or maximizing fuel efficiency, nor is it directly related to passenger comfort; rather, it plays an essential role in ensuring safe and effective aircraft control during a critical phase of flight.
