If a "sideways quickstop" stops you a little quicker, and you need this technique to avoid hitting something, then why were you there in the first place
Exactly... why are you trying to teach a PPL, or a CPL for that matter, this menouvre when they shouldn't be in this situation in the first place...??? This is a technical operational menouvre utilised to get your tail rotor away from anything that might rip it off, whether it is being thrown around for some reason close to the ground i.e. mustering or game capture, or as a quickstop menouvre when wanting to remain at a very, VERY low level, under radar/visibility of enemy i.e. in a military capacity.
If it is done correctly, technically like a normal quick stop, there isn't really any difference...
- you shouldn't get mast bumping if the disk is kept fully loaded,
- LTE is unlikely as the t/r disk is tilted at an angle (like the main rotor is tilted so you won't get vortrex - without sinking), and the speed isn't that fast when the t/r is kicked sideways
- the tailboom shouldn't come off as you're not throwing the tail out at 100kts - it should only be swung out towards the end of the menouvre if you're at a high speed, otherwise you're going way too fast way too low...!
besides the fact that if it does go wrong at the end (engine failure or t/r strike, you're going rolling instead of sliding.
I was involved in game capture and instruction for a few years and I was taught this menouvre by an ex-RAF test pilot, NOT TO BE TAUGHT TO PPLs...
and only as an OPERATION menouvre for situations where it might be neccesary......!
surely it is just part of a downwind quickstop
not at all.... a downwind quickstop is a where the heliopter is turned through 180 deg in a quickstop menouvre so that the nose is pointing into the wind at the end...
2 ways of doing it.....
- start the quickstop and then turn ending with a min of 30kts at 30 deg into wind and then coming to a stop
- turning first and then executing a normal quickstop as you are coming out of the turn...
and again, this isn't a normal PPL menouvre, even though it is taught in some parts of the world. You shouldn't be in the situation of being low level downwind, unless for operational purposes in a commercial operation where you have no other choice.
The downwind quickstop is also a military menouvre to bring the helicopter to a landing spot (into wind) while maintaining very low level under enemy eyes...
The unfortunate thing about a lot of military menouvres is they look fantastic when done, and they tend to creep their way into the general public, where newbies have seen such menouvres and want to know how to perform them... Instructor, be careful what you teach your students as they are, 9 out of 10 times, going to do them showing off to their mates.... and
always happens....and the CAA always asks "who taught him that?" Keep the specialist teaching for commercial pilots only where it may be neccesary and keep the
normal for others who
don't need it...
