Title: Tips for Inverting a C-182?
Post by: DakRadz on May 26, 2016, 07:08:01 PM
I'm about to do an Observer training with a local squadron, and wanted to see if I could get tips on inverting the plane. Always wanted to do it, and figured since the pilot has been flying for 25 years this is the best guy to ask- I'm sure he's done it before.

Anyway, is there a particular maneuver or style you are fond of or have heard about? Thanks.

Don't do it.

Try it in your mom's car first. Use the Vin Diesel "handbrake turn"...

1) Land the C-182 and taxi towards a large group of cadets. Encampments work best for this.
2) Explain what you want to the highest ranking cadet.
3) Watch as the cadets pick up the C-182, rotate it around an axis, and then put it back down upside down.

X-Plane is the only place I would consider such a maneuver.

I thought it said "Inventing a C-182." Got interested for a minute, thinking it was a time traveler from Wichita looking for advice.

I can only foresee turning on the news and seeing the headline be "Man Crashes Plane After Trying to Go Inverted"

The maneuver is very challenging for the body and you must train for it.

Best training is to find an oversized tire and large hill.  You'll need no fewer than 50 rotations per attempt in order to get acclimated, so make sure the hill is large and steep.   You'll probably need to complete this 10x daily for a minimum 3 week lead up time. 

Also, make sure you wear googles; ski googles work great.  And practice in full uniform, sleeves down.  This offers great crash simulation should the tire become unbalanced.

To invert a C-182, attach wire cable to crane and tie-down grommet of the aircraft tail.  Have crane pull up until aircraft is in a nose down attitude.  attach wire cables to wing tie-down grommets and a second crane.  Have 2nd crane pull up on aircraft until inverted; easy as pie.... >:D

(in the air, the maneuver is impossible; something about not having the correct oil system...) :o

BTW; make sure your personal insurance covers the attempt.  Gross negligence has its price...  ;D

It's not impossible.  The NTSB has all kinds of documented cases to prove it...

I stand corrected! ;D

It is possible, but very strongly discouraged. VERY. Getting it on its back is easy. Maintaining flight, not so much. The oil system is not designed for inverted flight.

I was in a 182 with a friend, and we got into a wing tip vortex from a heavy we thought was far enough ahead of us. We did a quick barrel roll, and flew to our destination. It was over almost before we knew it was happening.

Here are a couple videos showing how to invert a 172. A 182 probably wouldn't react much differently.

And a non-flip.

If you do attempt to fly a C-182 inverted make sure you are within gliding distance of a runway.
Because you WILL be getting some practice in performing a "dead stick" landing.
C-182 engines do not like zero oil pressure...

You can invert an aircraft and maintain positive G loading throughout the maneuver.  Can you accomplish this in a 182?  I'm not sure.

However, I stand by my prior advice of only doing this in X-Plane or other suitable sim.

Yes, you can, but the POH prohibits aerobatic maneuvers. However, a barrel roll, properly executed, is a 1G maneuver, and won't kill the plane. The fly upside-down stuff like Mav and Goose did with the MiG is totally out of the question.

As an afterthought, fuel delivery isn't set up for inverted flight, either, and is more of a consideration than the oil pressure.

I have a difficult time believing this was a serious inquiry, however anyone in my AOR who did something like
this on purpose, especially in a mission environment, would be an x-CAP pilot, and possibly an x-member before they closed their sortie.

CAPR 60-1, Page 6 2-1b:
"b. Smoking, aerobatic flight, spins (except instruction for a flight instructor certificate),
parachuting and dropping of objects (except to save a life) from CAP aircraft are prohibited.
"

That was a spin, not a roll.

Never said the video was a roll, though the poster of the video indicates the aircraft was inverted.

What was shown on the posted video was NOT inverted. Nose low and maybe 1 turn of a spin, but all right side up.

"You're about to write a check your butt can't cash!"

:P

Also, if you hypothetically were to do this, I would say said aircraft then deserves the honor of having this placarded on it for the rest of its service life:

Well, this has been quite entertaining. I have to wonder how many noted this was in Tall Tales (I, of course, don't try to be banned or locked, heh).

Good discussion though- thanks for the chuckle.
