Is “Green Dot” Always The Optimum Engines-Out Glide Speed On The Airbus A320 Aircraft?, Kivanc A. Avrenli, Barry J. Dempsey

Journal of Aviation/Aerospace Education & Research

The dual-engine failure checklist of the Airbus A320 states that the optimum airspeed at which the aircraft can be flown is the “green dot” speed when an engine restart is considered impossible. This is because the “green dot” speed maximizes the power-off glide range in wings-level flight. However, it is not known whether the “green dot” speed would still be the optimum airspeed if the power-off landing maneuver primarily consists of sharp turns. The objective of this study is to find out the optimum power-off glide speed for the A320 if the emergency landing maneuver primarily requires sharp turns rather …
