TASK 1048

Exract: TC 1-211 AIRCREW TRAINING MANUAL UTILITY HELICOPTER, UH-1H/V SERIES

TASK 1048
Perform fuel management procedures

CONDITIONS: In a UH-1 helicopter or UH-1FS with a CPU-26A/P computer (or equivalent) or
calculator.

STANDARDS: Appropriate common standards plus these additions/modifications:
1. Rated
 a. Verify that the required amount of fuel is on board at the time of departure.
 
 b. Initiate an alternate course of action if the actual fuel consumption varies from the
 planned value and the flight cannot be completed without the planned use of the required
 reserve.

c. Balance/manage fuel tank levels to maintain aircraft within center of gravity (CG) limits.

2. Rated/Nonrated.
 a. Initiate an in-flight fuel consumption check within 10 minutes after leveling off or
 entering into the mission profile.
 
 b. Compute the fuel consumption rate ±50 pounds per hour and complete the fuel check 15
 to 30 minutes after taking the initial readings.
 
 c. Monitor the remaining fuel quantity and the continuing rate of consumption.

DESCRIPTION:
1. Crew actions.

 a. The P or NCM will record the initial fuel figures, fuel flow computation, burnout, and
 reserve times. They will announce when initiating the fuel check and when completing the
 fuel check. The P or NCM also will announce the results of the fuel check.
 
 b. The pilot on the controls (P*) will acknowledge the results of the fuel check.
 
 c. The pilot in command (PC) will confirm the results of the fuel check.
 
 d. If applicable, the P will announce when the fuel transfer switch or fuel selector lever(s)
 are repositioned and when the fuel transfer operation is completed.
 
 e. The NCM will acknowledge and monitor the fuel transfer operation until the operation is
 completed.

2. Procedures.
 a. Before-takeoff fuel check. Determine the total fuel on board, and compare it with fuel
 required for the mission. If the fuel on board is inadequate, add sufficient fuel or abort or
 revise the mission.
 
 b. Initial airborne fuel reading. Within 10 minutes after leveling off or entering into the
 mission profile, record the total fuel quantity and the time of reading. Record the remaining
 fuel and the time of reading 15 to 30 minutes after taking the initial airborne fuel reading.
 Compute and record the consumption rate, burnout time, and reserve entry time. Determine if
 the remaining fuel is sufficient to complete the flight without the planned use of the required
 reserve. If the amount of fuel is inadequate, initiate an alternate course of action.
 Note: Crews should verify ability to transfer fuel from auxiliary to internal tanks before
 using auxiliary tank fuel quantities in fuel reserve/burnout computations.
 Note: Do not perform fuel consumption checks while transferring fuel from auxiliary tank(s)
 to internal fuel tanks.
 
 c. Fuel quantity and consumption. Periodically monitor the fuel quantity and consumption
 rate. If the fuel quantity or flow indicates a deviation from computed values, repeat the fuel
 consumption check to determine if the amount of fuel is adequate to complete the flight.
 Periodically check individual fuel tank indicators to determine that the system is operating
 properly.
 
 d. Auxiliary fuel management. The aircraft operator's manual outlines the procedures to be
 followed when auxiliary fuel tanks are used.
 NIGHT OR NIGHT VISION GOGGLE CONSIDERATIONS: The P should complete all duties
 associated with fuel management procedures. If the controls are transferred, the other aviator will
 verify fuel computations.

TRAINING AND EVALUATION REQUIREMENTS:
1. Training may be conducted in the aircraft or simulator.
2. Evaluation may be conducted in the aircraft or simulator.
