Which glide profile is best for maximizing time in the air during engine failure?

To maximize time in the air during an engine failure, the glide profile that focuses on maximum glide endurance is the most effective option. This approach enables an aircraft to stay airborne for the longest duration possible by optimizing the rate of descent relative to the lift generated.

When flying at maximum glide endurance, the pilot adjusts the glide to maintain the best lift-to-drag ratio, allowing the aircraft to remain airborne longer without power. This profile is especially important in emergency situations where the goal is not to cover the maximum horizontal distance but to prolong the time before landing, providing pilots with more options for a safe landing.

The other glide profiles have different objectives that do not align with maximizing airborne time. For instance, the maximum glide range focuses on covering the greatest horizontal distance, which necessarily involves a steeper descent angle and does not prioritize the time spent in the air. Similarly, the minimum drag profile aims at minimizing aerodynamic resistance but may not result in the highest endurance time. Lastly, the optimal climb rate is unrelated to gliding altogether, as it concerns how to gain altitude most efficiently, which is not relevant during an engine-out situation.

By focusing on maximum glide endurance, pilots can better manage the situation by maximizing their time in the air, allowing for thoughtful decision
