Perry just as a matter of interest please try a forward slip at
high altitude and
tell us what happens. For example is the canard stable or
does it buck in yaw or pitch? I am curious. The C 172 with full
flaps pitch bucks a little bit in a forward slip.

All Cessna's that I've flown do this.. I think you'll find that
most [if
not all] Cessna singles [ other than the 208 which I've not flown]
are not
approved for slip's w/ full flaps. I used to get into a divergently
unstable pitch situation all the time w/ a 182 when flying
skydivers.. it
was controllable when you were expecting it.. when you weren't
[ the first
few times it happened] it got your heart pumping.. Mind you..
these where
Max rudder on a straight tail 182, w/ enough bank to keep the heading
straight and then forward pitch until you reached Vfe and hold it
there..
w/ about 17inch MAP. Used to go from 2000 asl to 12000 and back to
2000[surface] in 18 minutes.. The other way to do it was Vne and
no flaps
and 17"MAP.. but in the summer bump's you'd lose sight of the
wing tip's
during the bumps.. not a really secure feeling.. We got paid by
the trip so
the faster the better.. :-) 27 trips in 1 day was enough to wear
ya out

Why do you think they are not approved for slips Jarrett?
Was it the pitch buck or was it some other reason?
I have always known that but it does not bother me to do them
anyway in my angled tail 182. As far as I can tell it does not
pitch buck like a 172. Maybe I am doing them wrong :)
Of course you can run out of gas as all the gas tends to
flow to the lower wing when the tank selector is on both.
But then again you are landing usually so you should not care
if the engine quits. Never the less I set the selector to the
upper wing. There is a scenario where someone may pull out on
the runway at the last minute.
Paul Lamar ...No rotor no motor.
I really couldn't say Paul, it could be for either of those reasons, I
would tend to think that most people wouldn't do a slip for minutes
on end
so the fuel starvation is then less of a concern, the instability
in pitch
is a bit more of an attention getter. Cessna's are ok for slipping
w/ the
flap's up so... most likely its the pitch issue w/ using flaps.
[ I'm
guessin']

I have always been curious about this and I never found anybody
that knew the reason. A lot of new instructors get freaked
out when they do my bi annuals and I slip it in :)

I learned to fly in a Luscombe which of course has no flaps and a big
rudder. After that I took some dual in a Pitts. Of course with both
of these slipping is the only way you are going to get it on the
ground. I can remember the first time I slipped a Cessna 152. I
Pushed the rudder over to the stops and the plane made this TINY
little response. It actually made me laugh. In the Luscombe you
could set the plane on its ear and drop like a rock (if that was what
you wanted) all in perfect control, I once did a forward slip from
8000 ft to 2000 ft. Jerry
