Which of the following correctly represents the best glide speed?

• A. The speed for maximum climb
• B. The speed for minimum drag
• C. The speed that results in the longest glide distance
• D. The speed necessary for safe approach

Answer: (C)

The best glide speed is defined as the speed that results in the longest glide distance. When an aircraft is in a descent without power, maintaining an optimal speed allows it to maximize lift while minimizing drag. This relationship is crucial during an engine-out scenario or any situation where maintaining altitude is not possible. By flying at the best glide speed, the pilot can ensure that the aircraft covers the most horizontal distance before reaching the ground. Interestingly, while options referring to maximum climb, minimum drag, and safe approach speeds are all important aspects of flight dynamics and operations, they do not directly correlate with achieving the longest glide distance, which is the primary concern in glide performance. This makes understanding the best glide speed essential for pilots, particularly when facing an emergency situation requiring a controlled descent.
