In the event of an engine failure after takeoff, what is the best glide speed?

The best glide speed is specific to each individual aircraft and can vary significantly between different models and designs. This speed is the velocity at which an aircraft will maintain the greatest distance over the ground while descending, which is critical in an engine-out scenario after takeoff.

Referring to the Pilot Operating Handbook (POH) is essential because it provides the necessary data for that particular aircraft, including its best glide speed in various conditions. Using the POH ensures that the pilot understands the performance parameters unique to their aircraft, including weight, configuration, and environmental factors that may affect glide performance.

Choosing a standard speed for all aircraft would not account for these variations, potentially leading to unsafe glide paths and decisions. Similarly, a fixed speed of 70 knots or a speed for maximum altitude maintenance does not account for specific aircraft characteristics, making them less applicable in real-world scenarios. Understanding and utilizing the POH allows pilots to make informed decisions that enhance safety and optimize glide performance in the event of an engine failure.
