Helicopters are able to take off without a great length available, from a hospital helipad for example. Generally, helicopters do not need a runway to take off and can do it directly from airports helipads, aprons or FATO (Final Approach and Take Off area).
There is also specific phraseology for helicopters (Helicopter flight Phraseology Example) that may be a little different from that used for airplanes
Take off manoeuvres
There are several techniques to take off and some are more complex than others.
Here is the list of most frequently used techniques:
- Take off from a hover
- Take off from a surface
- Running Take off
- Maximum performance take off (or Towering take off)
Take off from a hover
This technique is used most and requires the ability to perform a hover (Helicopter Hover)
- The helicopter is on ground, the cyclic pitch control is centralized, the collective pitch control pulled down and pedals are not used
- The helicopter is in a hover (Helicopter Hover) between 3ft and 5ft maximum
- The cyclic is moved forward smoothly in order to start the helicopter moving, the collective is used to prevent sink
- Helicopter accelerates through effective transitional lift and begins to climb, the nose rises up; use the collective to apply climb power and pull the cyclic forward
- As the helicopter continues to climb and accelerate, apply aft cyclic pressure to raise the nose smoothly to the normal climb attitude
Take off from a surface
This manoeuvre is similar to the one used to perform a "Take off from a hover" but for this technique there is no hover to perform
