Helicopter takeoff

[muppetdave]

I just watched a quick video of the AAC Apache's on facebook, and saw the Apache take off using a rolling approach. I seem to remember either in Chickenhawk or one about the RN's Lynx helicopters in the Middle East that rolling take-offs were required when heavily laden. I may be wrong, but the Apache didn't look desperately bogged down, but just seemed to be doing it as a matter of course.

Where possible, is it just easier for a helicopter if it has an undercarriage to do this (i.e. increase the speed over/under the 'wing' as with an aeroplane), or is there another reason?

Yeah very true and I think I did read that in one book. My suspicion is it's still predominantly to do with improved lift, but am not a flier.

Cheers guys.

(I was sure it was in Chickenhawk too )
