Emergency Descent
An emergency descent is a maneuver used to lose altitude rapidly when circumstances require an expedited descent while maintaining aircraft control and respecting aircraft limitations.
When an emergency descent may be needed
Situations requiring a rapid descent can include fire, smoke, pressurization problems in applicable aircraft, or another emergency in which remaining at the current altitude is undesirable.
The appropriate response depends on the aircraft, emergency, terrain, weather, and operating environment.
Aircraft-specific procedure
There is no single emergency-descent configuration or speed appropriate to every airplane.
Power setting, bank, airspeed, landing gear, flaps, propeller settings, and other configuration choices must follow the approved aircraft procedure and limitations.
Airspeed and limitations
A rapid descent can cause airspeed to increase quickly. The pilot must actively manage pitch, bank, power, and configuration to remain within applicable limitations.
Abrupt control inputs can create unnecessary load factor or lead to an unstable recovery.
Traffic, terrain, and direction
A rapid descent does not remove the need for awareness of other aircraft, terrain, obstacles, airspace, and weather.
The pilot should maintain an effective visual and instrument scan while using the emergency procedure appropriate to the circumstances.
Level-off and recovery
The maneuver must be terminated with enough anticipation to avoid exceeding the intended altitude or creating excessive aircraft loading.
Power, pitch, bank, and configuration are returned according to aircraft procedure as the airplane transitions to the required subsequent flight condition.
Common emergency-descent errors
- using a generic technique instead of the aircraft procedure;
- allowing airspeed to exceed a limitation;
- poor traffic or terrain awareness;
- abrupt control inputs;
- fixating on descent rate instead of overall aircraft control;
- poor anticipation of the recovery or level-off;
- incorrect configuration management.
Why pilots practice emergency descents
The maneuver develops familiarity with rapid changes in altitude, airspeed, bank, and configuration while workload is high.
Practice also reinforces disciplined use of aircraft limitations and emergency procedures.
Useful practice considerations
Depending on the aircraft, conditions, training objective, applicable standards, and instructor guidance, practice may include:
- recognizing the circumstances requiring a rapid descent;
- using the aircraft-specific emergency procedure;
- maintaining airspeed within applicable limitations;
- managing bank, pitch, power, and configuration;
- maintaining traffic and terrain awareness;
- monitoring altitude throughout the descent;
- anticipating recovery or level-off;
- transitioning smoothly to the required subsequent flight condition.

Last Practiced lets you record the date you practiced emergency descent alongside the other individual flying skills from the same session. You can also set a personal Practice Target if this is a skill you want to revisit at your own chosen interval.
Practice Targets are personal reminders. They do not establish regulatory currency, proficiency, or legal eligibility to fly.
