I think I know. In the mid '70s sometime, I was giving a BFR to a guy in an
Arrow. Just before rotation and liftoff, he quickly reached over and
flipped up the gear lever. It was so quick, I was petrified an hypnotized
at the same time. After we got out out of the area I asked him in a real
stern voice, "What did you just do!". He explained how the squat switch
worked, like I didn't know, an continued to tell me how he likes to get that
all out of the way so he can concentrate on reducing MAP and RPM, turning,
etc. This guy was doing this for the last 200 hours in his Arrow. We
continued the discussion when we got on the ground. I also changed my
behavior to always be ready for the hand coming over with any pilot in a
retract gear airplane. I happened so quick.

So many OWTs that get the "average" pilot into trouble.
Relying on the squat switch to keep the gear down is one of the
stupider ways to wreck a good airplane. On the Cessna single retracts,
the squat switch is on the nosegear, since the mains are spring tubes
and there's no relative movement to use to activate a microswitch. The
nosegear strut closes the switch when it's extended, and since these
oleos are known to get sticky, the switch can be closed with the
airplane on the ground. Sitting still. With the engine off. They are
often closed immediately after landing in the rollout, especially on
the 182RG, whose mains are farther forward and an aft CG will keep the
strut extended. The nosegear retracts forward and will do so with
incredible speed with any amount of weight at all on it. We have a
rule that the pilot doesn't touch the flaps until he's stopped, since
some can get the flap and gear levers mixed up, especially while still
rolling and their attention is divided. We've had a couple of close
calls with that.
You can count on spending many AMUs if you retract that
nosegear on the ground, whether the engine is running or not. A
running drop is just much more expensive. Fooling with the gear lever
while on the ground is just plain stupid, as is ignoring the checklist
item that demands that you make sure the lever is down before you
switch on the master.
In the flight training industry we hear of such dumb things
all the time.

I also don't like dealing with flaps in the roll out and discourage this
practice in new pilots. There's only one concern during the roll out;
that's aircraft control. Plenty of time to clean it up at the turnoff.
Of all the dumb things a pilot can do in an airplane, relying on a squat
switch has to be near the top of the list.
Pilots flying older airplanes with hydraulic gear systems have
additional issues to consider. Many of these airplanes will indeed
retract if the gear handle is misused on the ground. The Navion I
believe has this issue.
Warbirds are particularly susceptible. The P51D for example, has a
mechanical downlock that prevents the gear handle from being selected UP
on the ground IF the fairing door release handle has been pulled and the
aircraft is parked. When the engine starts, the doors retract, and the
linkage is lost. If you are taxiing a P51 and hit the gear handle to the
up position, you stand a VERY good chance of having a much lighter
wallet soon thereafter :-))

Aw, do you mean you had to look it up and didn't know it already?

Of course I didn't know. I did a search, *Banshee kneeling*.

LOL, by process of elimination, I've never heard of

so how could I loose?
It's light, just an additive to the thread, that some
fella's might be interested in, that's all, no big deal.

Plenty of practice.

And it's "lose", fjukktard.

Of course I do, that's because I am. But I've never retracted the gear

I certainly haven't gone around making idiotic statements like you
just did, either.

Hitting the gear switch on some of the old hydraulic system airplanes on
the ground could produce "interesting" results.
I believe Ron Natalie checked in with some comment on the Navion. He and
Margy own one.
It's been years, but I seem to remember a clear warning in the Navion's
manual directed to this issue.


The gear handle DOWN is on the pre-start checklist for good reason. We
had a friend who'd just spent MONTHS working on his plane. The plane
was standing there in the hangar looking proud and he cranked the engine
and the nose gear gave way and it spent many more MONTHS in the hangar.
He was NOT happy with himself. I'm sure he checks the handle position
much more carefully now.
