TASK 1074
PERFORM SIMULATED ENGINE FAILURE AT CRUISE FLIGHT

CONDITIONS: In a UH-1 helicopter, with an instructor pilot (IP), and above 400 feet above ground
level (AGL); or in a UH-1FS.

STANDARDS: Appropriate common standards plus these additions/modifications:
1. Recognize the emergency, determine the appropriate corrective action, and perform or
simulate (as required) from memory all immediate action procedures required.
2. Select a suitable landing area.
3. Correctly terminate maneuver as directed by the IP.

DESCRIPTION:
1. Crew actions.

 a. The pilot on the controls (P*), upon detecting the engine failure, will initiate the
 immediate action steps in accordance with the operator’s manual. He will remain focused
 outside the aircraft, select an appropriate landing area, and call for the checklist to verify his
 response.
 
 b. The IP will announce: "Simulated engine failure" and provide adequate warning for
 corrective action, if engine operating limits may be exceeded. The IP will confirm the proper
 execution of immediate action steps.
 
 c. The nonrated crewmember (NCM) will continually monitor the condition of the aircraft.
 He will simulate preparing passengers for crash landing and perform any other duties as
 directed by the P*/P (pilot not on the controls).

2. Procedures.

 a. Upon detecting engine failure, the P* will lower the collective to maintain rotor
 revolutions per minute (RPM) within limits while adjusting the pedals to trim the aircraft.
 The P* will select a suitable landing area and, using turns and adjusting airspeed as
 necessary, maneuver the aircraft for a safe landing to the intended landing area. (The final
 approach should generally be into the wind.) The P* will direct the IP to simulate setting the
 governor switch to EMER. If time permits the P* will direct the IP to set the transponder to
 EMER and transmit a Mayday call on the GUARD frequency. The standardization instructor
 pilot (SP)/IP will monitor the rotor RPM, gas producer, and aircraft in trim through out the
 maneuver. The P* should plan each forced landing as if continuing to the ground.
 
 b. Prior to reaching 400 feet AGL with the aircraft in a safe autorotative profile, the IP will
 state one of three commands: “power recovery,” “Terminate with power,” or “Touchdown.”
 (The emergency procedures training criteria outlined in AR 95-1 must be met before
 touchdown autorotations are performed.) The P* performs the following actions during these
 autorotations.
 
(1) Power recovery. Upon receiving the command "Power recovery," immediately
establish normal operating RPM by smoothly adjusting the throttle to the fully open
position. Maintain the aircraft in trim with the pedals. After normal operating RPM has
been regained, increase the collective to establish a normal climb prior to reaching 200
feet AGL.

(2) Terminate with power. Upon receiving the command "Terminate with power,"
continue the autorotative descent. Prior to reaching 100 feet AGL, reestablish normal
operating RPM, adjust the collective as necessary trim the aircraft with the pedals, and
maintain the autorotation. At approximately 100 feet AGL, apply aft cyclic to initiate a
smooth, progressive deceleration. Using the cyclic and pedals, align the aircraft with the
intended landing area. Adjust the collective, if required, to prevent excessive rotor RPM.
At approximately 15 feet AGL, apply sufficient collective to control the rate of descent
and ground speed. The rate of descent and ground speed should be zero at 3 to 5 feet
AGL with the aircraft in a landing attitude.

(3) Touchdown. Upon receiving the command "Touchdown," continue the autorotative
descent. At approximately 100 feet AGL, apply aft cyclic to initiate a smooth,
progressive deceleration. Maintain aircraft alignment with the touchdown area by
properly adjusting the pedals and cyclic. Adjust the collective as necessary to prevent
excessive rotor RPM. At approximately 15 feet AGL, apply sufficient collective to
control the rate of descent and ground speed. (The amount of collective applied and the
rate at which it is applied will depend on the rate of descent and ground speed.) Adjust
the cyclic to attain a landing attitude, and apply collective as necessary just prior to
touch-down to cushion the landing. After touchdown, maintain ground track alignment
with the pedals. When the aircraft has come to a complete stop, lower the collective and
neutralize the pedals and cyclic.

Note: When the task is conducted in the aircraft, the IP will initiate the maneuver by
announcing "Simulated engine failure." When conducting training and/or evaluation for SPs
or IPs, the maneuver may be initiated with no announcement.

Note: The aircraft operator's manual contains details about the procedures outlined in the
aircraft checklist.

NIGHT OR NIGHT VISION GOGGLE CONSIDERATIONS:
1. If performed in the aircraft, this task is prohibited at other than designated areas.
2. If the searchlight or landing light is used, it should be turned on prior to entering the
maneuver. Ensure that the searchlight or landing light is in the desired position.
3. Use of the white light may impair night vision for several minutes. Therefore, exercise added
caution if resuming flight before reaching full dark adaptation

TRAINING AND EVALUATION REQUIREMENTS:
1. Training will be conducted in the aircraft.
2. Evaluation will be conducted in the aircraft.
