TASK 1040 Perform VMC Takeoff
CONDITIONS: In a UH-1 helicopter with the hover power and before-takeoff checks completed.
STANDARDS: Appropriate common standards plus these additions/modifications:
1. Maintain takeoff heading ± 10 degrees below 50 feet above ground level (AGL).
2. Maintain desired ground track.
3. Maintain aircraft in trim above 50 feet AGL or as appropriate for transition to terrain flight.
1. Crew actions.
a. The pilot in command (PC) will determine the direction of takeoff by analyzing the tactical situation, the wind, the long axis of the takeoff area, and the lowest obstacles. The PC will
confirm that required power is available by comparing the information from the performance planning card (PPC) to the hover power check.
b. The pilot on the controls (P*) will remain focused primarily outside the aircraft throughout the maneuver to provide obstacle clearance. The P* will announce whether the takeoff is from
the ground or from a hover and his intent to abort or alter the takeoff. The P* will select reference points to assist in maintaining the desired ground track.
c. The pilot not on the controls (P) and non rated crew member (NCM) will announce when ready for takeoff and will remain focused primarily outside the aircraft to assist in clearing and
to provide adequate warning of obstacles. They will announce when their attention is focused inside the aircraft and again when their attention is reestablished outside.
d. The P will monitor the instruments and advise the P* if power limits are being approached.
a. From the ground. Select reference points to maintain the desired ground track. With the cyclic and pedals in the neutral position, increase collective. As the aircraft leaves the ground,
maintain heading with pedals and apply forward cyclic as required to smoothly accelerate through effective transitional lift (ETL) at an appropriate altitude for the terrain and to avoid obstacles.
Adjust the cyclic as necessary (approximately 5 degrees nose down), obtain the desired climb airspeed, and maintain the desired ground track. Position the collective as necessary to clear
obstacles in the flight path, and obtain the desired rate of climb. Maintain heading with the pedals when below 50 feet AGL or until transitioning to terrain flight; place the aircraft in trim above 50 feet AGL.
After obtaining the desired airspeed, adjust the cyclic as necessary to stop the acceleration. Adjust the collective to continue or stop the rate of climb as required.
b. From a hover. Select reference points to maintain desired ground track; maintain heading with the pedals. Apply forward cyclic to smoothly accelerate the aircraft through ETL while adjusting
the collective to maintain the appropriate hover height. Perform the rest of the maneuver as for a takeoff from the ground.
Note: Avoid unnecessary nose-low acceleration attitudes. Do not exceed 10 degrees nose low.
Note: Performing this maneuver in certain environments may require hover out-of-ground effect (OGE) power. Evaluate each situation for power required versus power available.
Note: The P* should determine the torque required for the planned takeoff technique and announce the value to the P and NCM(s).
Note: For training, recommended climb airspeed is 70 KIAS with a rate of climb of 500 FPM.

For this task you will be taught different techniques for taking off in the Huey. This will include:
Constant angle takeoff, good for formation flight.
Airspeed over altitude takeoff, used when aircraft is heavy and power limited.
- Altitude over airspeed takeoff used for confined areas or dust & snow.
Your Basic Wings evaluation focuses on traffic pattern flying. Your takeoffs during the evaluation will be geared for those maneuvers.
You will be asked to accelerate the aircraft to 60 KIAS and then maintain that airspeed until you reach 400ft AGL, at which point you will make your 90° crosswind turn.
