Gliding With Precision
From almost our very first flying lesson, pilots are taught what to do in the event a single-engine airplanes lone powerplant fails. As with too many concepts at that early stage of our training, we basically accept what were taught without many questions. Later, as we gain experience, we begin to think more about those early lessons and try to apply to them what our experience has taught us. In turn, many questions can arise. If your airplane ever becomes a glider, you would suddenly become very interested in its new aerodynamics. How promptly and accurately you can remember to make the most of the variables at your disposal would play a large part in determining where and how softly you land. Lets take a look at those variables and how they can affect your emergency glide.
Key Takeaways:
- Upon engine failure, pilots must prioritize flying the aircraft, immediately establishing the "best glide speed" (which maximizes range by achieving the optimal lift-to-drag ratio), and identifying a suitable landing area.
- Best glide speed is not static and must be adjusted based on atmospheric conditions (increased for headwinds/downdrafts, decreased for tailwinds/updrafts) and aircraft weight (decreases with lighter weight).
- Increased drag, such as from extended flaps or landing gear, significantly steepens the glide angle, reduces overall glide distance, and requires a lower corresponding best glide airspeed.
