STALLS !

Postby Camell » Mon Jan 22, 2007 6:33 pm

How about some tips for stalls?

I'm sure most of us will appreciate a re-cap of our training, and this obviously comes in handy for the Flight Test.

Not a good idea when flying low :roll: :lol:

Personally I love doing stalls, very thrilling.

- Don't let the wing drop
- Don't stall such that your feet are above the horizon, increases tumble probability esp with powered stall ie quick into the stall.
- Use small slowish movements of the bar not sudden and fast, you aren't trying to do a loop.

I dont like practicing stalls, probably because I have been scared s**tless viewing video clips of trike tumbling.

Recognising the fact that I dont like stalls, I feel I need to be able to master them, especally for the MPL flight test and to be able to recognise them, should they occur. I just dont want to practce a stall and land up in a whipstall!

Personally, I don’t do stalls

=; -xX -xX IMHO :!:

Pulling the bar back is the 2nd ingredient required to generate a tumble or tuck ….. The 1st being over-aggressive pitch to allow for a whipstall …

Personally, I don’t do stalls but I do practice low airspeed pre-stall recovery quite often … :lol:

But then, I am not an instructor either … :oops: :oops:

Practicing stalls is an area that we all neglect. We have to stay current and know what to do when we accidentally end up in a stall and need to recover quickly. It bites you when least expected.

Dad,

stalling a trike and stalling a 3-axis are two moerse different things. 3-axis are easy and safe to perform with altitude. Trikes have that inherent risk of a slightly over-enthusiastic push and the resulting deadly whip stall and tumble.

If it were me, but then I am a very cautious pilot, I would not practice stalls in a trike but rather recognising the indications of a stall and stall avoidance.

I think it was last year January when a 300 hour instructor deliberately stalled his trike in order to loose height, the push was too hard, the trike tucked and he fell 1000 feet to his death. This was somewhere up near De Wildt I think. Don't practise something that has the potential to kill you because no matter how good you are someday it will. It's called risk avoidance IMHO (stepping off pedestal and swiftly walking away)

Ouch morph now thats a big deterrant from practicing :shock: . Stalling to lose height is not a good idea in any case, surely snaking is the way with a trike?

Also the mush is easy to detect in a trike. Having flown 3 different trikes this week I see the feet above the horizon also depends on which trike you flying... :shock:

Aquilla has a high nose attitude by default, Raptor more level. So applying the same rule to both would be unsafe in the one or "too safe" in the other...?

Sage advice!

Unfortunately its one of the things you need to be able to do (without killing yourself and the instructor) for your flight test

recognising the symptoms of a stall and recovery from a stall were both required in my Flight Test.

As long as you have been instructed correctly they are nothing to fear and should be practised. Get your instructor to go through them with you until you are comnfortable then practise them with no pax.

Basically, off the power and push the bar forward attempting to keep the trike flying level. Once you feel the stall, bar back to neutral (gently, don't jerk it back) and at the same time power on. You will feel the recovery happening and once back in straight and level flight off the power to cruise. Any instructors please comment on this technique.

I teach different stalls. Power on to test, power off, and power on recovery from a stall.
Firstly, at cruise power i.e straight and level, gently keep pushing the bar foward, until you feel the wing start to stall. This should give you an indication of where your wing will stall.
Next, power off, gently push the bar forward, to the stall postion, and beyond. trying to get to the Profile tube. Trike should just mush, and wallow, correct the wing if it tries to drop. Practice this with lots of height, 2000 ft agl, calm weather, and enter each stall a little more. Most wings will allow you to go to the profile tube, with no problem. Always relax the bar gently back to neutral, and apply power. NEVER jerk the bar in.
Next, power off, pull bar in slightly, for a LITTLE extra speed, and push bar out to the now recognised stall piont, either on the profile tube, or just back. Nose will lift, then drop slightly. Bar back to neutral, power on again. AS before, test this slowly, until you get to know your wing.
Next, and very important of students, is power on recovery from a stall.
You now know how and when your tike stalls.
Power off, bar in slightly, slight extra speed, push bar out until the stall position is reached, hold there until just before the actual stall, recognise it, and go IMMEDIATELy to full power, to recover from the stall. Relax the bar slowly back to neutral, fly away without loosing height. This very important exercise will save you and your trike when you balloon in the circuit.
All movements and testing is done by pushing and pulling gently, with no sudden jeks in or out.

Buffeting, lack of wind in the face, wing wanting to drop, going all mushy, heavy etc are symptoms. Some wings might want to drop a wing, catch and correct.
Depends a LOT on what you fly. Old big wings are normally very forgiving, new high performance wings more likely to bite.
If not sure, ask an experienced instructor to go with you, preferably one who knows that make of trike

I teach the same three techniques as Larry, Power on stall, Power off stall and recovering from a stall with minimum height loss.
