Introduction: Emergency descents are used when you need to lose altitude quickly. This is could be simply for losing altitude or (more commonly) to get to a land site quickly. This is usually because of a potentially dangerous situation with the aircraft such as a fire, smoke in the cockpit or due to an emergency decompression on pressurized aircraft.
A. Lesson Requirements:
- a. Task: Perform an emergency descent.
- b. Condition: Given a functional aircraft.
- c. Standard: IAW the PTS.
- i. Exhibits knowledge of the elements related to an emergency descent.
- ii. Recognizes situations, such as depressurization, cockpit smoke and/or fire that require an emergency descent.
- iii. Establishes the appropriate airspeed and configuration for the emergency descent.
- iv. Exhibits orientation, division of attention, and proper planning.
- v. Maintains positive load factors during the descent.
- vi. Completes appropriate checklists.
B. ELO 1: Understand the use of an emergency descent.
- a. What could cause an emergency descent? Anything that would require that the airplane lose altitude quickly while still being under control. (Engine fire, emergency decompression, smoke in the cockpit, etc)
- b. What are the limitations on an emergency descent? NEVER exceed Vne, Vle, Vfe. Do not exceed a 45 degree bank. In multi-engine aircraft turn INTO the operating engine.
- c. Student Check:
- i. What are Vne, Vle and Vfe of this airplane? _______
C. ELO 2: Identify common errors in the emergency descent.
- a. The failure to identify the need for the descent. Stay on top of the airplane. Be ahead of the airplane.
- b. Failure to use the proper checklists. Use the checklist as soon as you have the airplane under control.
- c. Failure to maintain proper configuration. Get the plane in proper configuration for the turn. Refer to POH.
D. ELO 3: Perform an emergency descent.
- a. Reduce power to idle.
- b. High RPM on the propeller.
- c. Extend gear.
- d. Full flaps.
- e. Close cowl flaps.
- f. Turn 45 degrees to one side. For multi-engine airplanes turn into the good engine.
- g. Get checklist to finish troubleshooting.
