How many feet of increased altitude can be gained from trading 10 knots of extra airspeed during an Emergency Landing Pattern (ELP)?

In an Emergency Landing Pattern (ELP), the relationship between airspeed and altitude gain is an important concept for pilots to understand. When a pilot trades airspeed for altitude, generally, the aircraft can gain approximately 100 feet of altitude for every 10 knots of extra airspeed. This conversion is based on the aerodynamic principles that govern lift generation and drag.

During an ELP, if a pilot increases airspeed by 10 knots, the additional lift generated allows the aircraft to climb higher for a brief period before reestablishing a normal glide configuration. This altitude gain is crucial for clearing obstacles and safely aligning with the runway for landing. By adhering to the 10 knots to 100 feet rule, pilots can effectively manage their glide and plan for a safe landing, confirming that the choice of 100 feet is based on these well-established aerodynamics.
