What is the initial descent speed recommended during an emergency descent?

The initial descent speed recommended during an emergency descent is generally around 124 knots for light, single-engine airplanes. This speed is advantageous as it strikes a balance between efficient descent and maintaining aircraft control. At this speed, the aircraft is typically operating within a range that allows for a stable descent while providing adequate aerodynamic control response.

This speed helps ensure that the aircraft can descend rapidly while still being manageable, as excessive speeds can lead to difficulties in controlling the aircraft during such a critical situation. It is also important to note that this speed may vary depending on specific aircraft performance characteristics; however, as a general guideline, 124 knots offers a good reference point for pilots.
