VMC Rollover, ever done it?

[CarjCapt]

vmc

Unless my memory is just plain wrong, I remember that none of the multi-engine aircraft certified in the last 40+ years have never been tested and certified for spins of any kind.

To do a VMC demo and let it go too far can lead to a spin that you can't recover from at normal demo altitudes.

Again from memory, Piper did some spin test with the then new PA-30 (twin comanche) and found it took in excess of 10000 feet to recover.

Some one with a better memory please correct me if I'm wrong.

But I would never spin a multi-engine twin of any kind intentionly or get it in a situation that could lead to a spin.

I own a PA-30 and while researching the plane I found out that it received a bad rep because it was then used as the Seminole is now .. and during training, way back when, multi students had to do VMC demos at 500 AGL or something *ridiculous* like that. Many PA-30's crashed and now the PA-30 has stall strips on the leading edges and the FAA had redline moved higher by 5-10mph .. which CLEARLY isn't true if you fly the plane because the plane wants to DESPERATELY fly below redline.

What I do is just hold it in ground effect (don't want to allow the nose wheel to over-stress and break) and then once I'm past redline, resume climb. Many PA-30 pilots hold it onto the runway and the mx bills for that nose gear must be brutal.

Lastly, yes, the PA-30 used up a lot of altitude to recover and you *can* put it into a flat spin. In icing, the tail stalls FIRST ..

Its a great airplane though .. no one makes a twin that nice anymore.

As I remember the Twin Commanche had VMC speed changed from 80IMPH to 90IMPH and that was before I go my multi-engine rating in the pa-30 in 1970

CarjCapt's picture reminds me of the days when all of the CONUS NOTAMS were posted on a large vertical obelisk in Base Ops.

What's going on in that picture?

...What's going on in that picture?

All the mx squawks from my flight school?

That is CMR's management TA piled in front of the Chief Pilot's office prior to our strike.

A beautiful picture indeed.

a question.. why is a multi so much more difficult to deal with in stalls, spins? My instructor never let us get anywhere near a full stall or spin in our geronimo, but never really explained why a spin was so much more dangerous in twin..? Does retarding the throttles, level wings, and forward elevator not work as well for some reason? Or does it just take a lot more altitude?

Correct me if I a wrong but from what I remember the Vmc for a PA-23 is hihger than stall speed.

Don't see the problem with the full stall. But spins are prohibited in most twin engine aircraft.

You also need to realize that you are most likely learning how to fly a machine that your instructor can barely fly himself. Do you really want to test his VMC skills if an engine is lost during recovery from a full power off stall?
