King Air's are not light twins.

Er, King Airs.

Don't you hate it when the spell check adds punctuation you
don't want?

Yes, they are, they do not require two pilots. They do
weight more than 6,000 pounds, but that just means the FAA
requires an ability to climb at 5,000 feet.

You call those light twins? I call them turboprops. To me a light twin is one
where you can't walk down an aisle inside... ie, smaller than cabin class. That
means airplanes such as the Duchess, Seminole, Aztec, Seneca, C-310, etc.

Compared to airliners, sure, I can see where you might consider a King Air a
light twin. But very few of us get to start in one and yet I do have a bit of
twin time, mostly in light twins and maybe a third of it in cabin class. I
doubt any of them could get out of their own way on takeoff with only one fan
turning.

I consider a high performance airplane as one that has
cruise speed above Va, because it requires a deft touch in a
spiral recovery since you are always above the speed where
you can break the airplane. You are trimmed for, let's say
175 and get into a spiral. By the time you discover the
error and begin recovery you are 25-50 knots above Va. You
do the recovery the way you were taught and pull power,
level the wings and pull the nose up. You also die.
The trim is going to do the pull up as you get the bank
angle into the 30 degree or less range since you are very
much above trim speed. The proper recovery in such a plane
is pull the power, hold the wheel forward and level the
wings, controlling the rate at which the nose comes up to
control the G loads. That is my definition. But the FAA
says that it is just anything with an engine over 200 hp.

FAA Part 1.1
Large aircraft means aircraft of more than 12,500 pounds,
maximum certificated takeoff weight.



§ 23.66 Takeoff climb: One-engine inoperative.
For normal, utility, and acrobatic category reciprocating
engine-powered airplanes of more than 6,000 pounds maximum
weight, and turbine engine-powered airplanes in the normal,
utility, and acrobatic category, the steady gradient of
climb or descent must be determined at each weight,
altitude, and ambient temperature within the operational
limits established by the applicant with-

(a) The critical engine inoperative and its propeller in the
position it rapidly and automatically assumes;

(b) The remaining engine(s) at takeoff power;

(c) The landing gear extended, except that if the landing
gear can be retracted in not more than seven seconds, the
test may be conducted with the gear retracted;

(d) The wing flaps in the takeoff position(s):

(e) The wings level; and

(f) A climb speed equal to that achieved at 50 feet in the
demonstration of §23.53.

King Airs probably could, if you could get them going straight in the
beginning. But no, it's a LIGHT TWIN, with conventional Lycoming 180HP
engines. It's NOT a Piper.

The 300/350 has to do it once past V1. And by definition you have to be past
Vmcg, which might take Edwards AFB for the required runway length. King Air
doesn't taxi well on one engine, BTDT.

I have witnessed this airplane do it in relative safety.

Somebody tried to do this once on purpose in a Lear Jet out of KPDX about 25
years ago. He didn't make it.

The Twin Commander 690/695 series with the Dash-10 conversion is another
series. Single engine ceiling with that series is over 20,000 feet.
