Anyone see the new video on Avweb???

I wonder if you can log multi-time in that...


I can't think of any reason you wouldn't be able to. You would be able to
log single engine time comparable aircraft that only had one engine.

I agree, but think about it, if one engine fails, you can't control the
thing at all (AFAIK), so even though it has two power plants, for all
intents and purposes, I would not consider it a "real" twin.

Now, I know if you look up in the regs, I'm sure it'll say simply "a
multi engine plane is one with more than one engine", but IMO this kind
of thing should be made an exception; kind of like how they have an
"exception" for centerline thrust planes. You don't need any kind of
special multi-engine training to be able to fly it, so why would you
need a multi-rating?

Why not? Considering the kind of aerobatics it did in the video, I'd
guess there's plenty of rudder authority.

BECAUSE of its design, the Cri-Cri flies quite well (control wise) on one
engine.

The Cri-Cri ...IS A REAL TWIN!+!

OK then I stand corrected.

But the question still remains: if there was a twin that happened to
have 2 engine, but absolutely could not be controlled with one engine,
should it be considered a twin?

Come to think of it, I don't think it would even matter. Any plane a
company wants to bring to market need to be certified and tested by the
FAA. I don't think the FAA would allow a twin to be sold in the US if
it couldn't be flown with one engine inoperative. An ultralight could
exist with this condition, but the FAA doesn't certify them (AFAIK),
but you don't need a certificate either. Are there any planes out
there that have two engine, but can't be flown on one?

Really? CAN'T? Even at partial throttle?

I didn't know that.

Corky Meyer:

"Where the aircraft really came into its own was in performing stalls. The
counter-rotating propellers kept the aircraft pointing straight ahead, so
there was no torque effect to require rudder input as the speed decreased.
Stalls demonstrated a good, early buffet warning, and no wing dropping
occurred at the stall, even with small, pilot-applied aileron and rudder
inputs to try to irritate its lateral and/or directional attitudes near
the stall. It was even more impressive to me when I performed single-
engine stalls with one engine either windmilling or feathered. With one of
the P-38's dual fins and rudders always in the slipstream of a live
engine, a stall could be performed with little or no wing drop. It was a
pilot's dream under the trying conditions of a single-engine approach and
landing."

"The 5,000th Lightning built, a P-38J, was painted fire-engine red, and had
the name 'YIPPEE' painted on the underside of the wings in big letters.
This aircraft was used by Lockheed test pilots Milo Burcham and Tony
LeVier in remarkable flight demonstrations, performing such stunts as slow
rolls at treetop level with one prop feathered to show that the P-38 was
not the unmanageable beast of legend. Their exploits did much to reassure
pilots that the Lightning might be a handful, but it was no 'widow maker.'"

The "Critical Engine" problem ...(x)2 ...was mainly an issue on takeoffs. My
bad. I've been set straight, so to speak.

http://www.fighter-planes.com/info/p38_lightning.htm
[That would not be until later, however, and the new P-38 had other defects.
The most dangerous problem was that both engines were "critical"
engines-losing one on takeoff, which happened often, created "critical
torque," rolling the plane towards the live engine's wingtip, rather than
the dead engine's. Normal reflex in pilots flying twin engine aircraft would
be to push the remaining engine to full throttle when they lost an engine on
takeoff, but in the P-38, the resulting critical torque would produce such
an uncontrollable level of asymmetric roll that the aircraft would flip over
and slam upside-down into the ground. Eventually, procedures were devised to
allow a pilot to deal with the situation by reducing power on the running
engine, feathering the prop on the dead engine, and then increasing power
gradually until the aircraft was in stable flight.]

Are you under the assumption that you don't need a MI rating to fly a
Skymaster?
