Sorry guys, but:—

1) Until now, I’ve never heard of any limitation on sideslipping a 150/2 or 172 with full flap. Cessna seem to be equally puzzled by the various theories floating around on this and answered a query from a pilot on sideslipping—their response is given on the ‘Landing Long’ thread in the Private Flying Forum);

2) The only sideslip limitation I’m aware of on the PA28 (Arrow, anyway) is that “prolonged slips or skids which result in excess of 2000 feet of altitude loss...which could cause uncovering of the fuel outlet must be avoided as fuel flow interruption may occur when tank being used is not full”.

Hope this helps.

Well now look what you've done, HP!!!

Certainly buggered up that discussion - just as it appeared to be approaching the flare you seem to have declared a go around.

Anybody going to type in the relevant paragraphs from their POH?

(Don't you just love it when a plan comes together? [How should I know?])

I don't have it on me at the moment, but my Cessna POH for the model 172N says avoid slips with flaps greater than 20 degrees (italics mine). It doesn't say slips with flaps are prohibited.

Squawk 8888:— Correct. It’s a cautionary note, NOT a limitation.

Apparently it’s something to do with weakened airflow over the tailplane which causes mild oscillations, according to Cessna. Doesn’t apply to 150/2s.

Bear Cub:— I won’t fall into the same trap with your flap/crosswind thread! :)

Bingo !!, found the answer hidden away in the depths of my C172 POH.

In the placards section it states 'Near flap indicator- "Avoid slips with flaps extended"'

Very nice but why ? most people would ask. If I've got an engine failure and need to get down into the only suitable field, you can bet your ass I'm going to sideslip with full flap if I have to. It would be nice to know what to expect though.

Fortunately if you then carry on through to the normal procedures section and read the bit on crosswind landings all is revealed.

It states the following -

"If flap settings greater than 20Deg are used in sideslips with full rudder deflection, some elevator oscillation may be felt at normal approach speeds. However, this does not affect control of the airplane"

Nice one, if that's the case then I'll be taking my chances with the oscillations in an emergency !!

I did wonder about the answer I gave in my previous post though. I definitely read somewhere that some bloke had tried it and that he said it was rudder blanking he had problems with ??
However I've been racking my brains and scouring my ATPL notes trying to find a way that would be possible and I cant think of one so he must have been talking balls.
Elevator Blanking is your answer then, I think I'll go and give that a try tomorrow if the weather is half decent, will be nice to try something new for a change !! :)
