Luc you need to add to that comment with

I'm getting a twin rating and a twin Beech........

Charles, you need two things, good MX and sim training. Turbines are better at SL but look at the SE climb performance for a C90 on a hot summer day at higher elevation airports.

Sim training is great, but if I lose an engine at rotation departing HKS at 7450lbs and 95F it's game over. (Which is why I'd be at 7000lbs or at JAN)

Every TO should be planned with good risk management. Sometimes I use longer runways or reduce weight.

Sim training helps here, too, as it sharpens your response time so you make the right decision, even if it is to land off airport.

It isn't the off airport landing, it is the Vmc roll over you have to avoid.

If a pilot has never been in a sim, they have NEVER had a realistic engine failure on takeoff. Why do we expect them to handle the first one they ever get?

When a pilot who has never been in the sim experiences the first one, it is an eye opening thing. When they experience their 10th one, it is almost boring, they are so much more proficient.

Twin is still beneficial in this scenario.

In a twin, you climb much faster to an altitude you can glide back to the airport. This is due to climbing faster and due to having a more shallow glide with one engine still operating.

In a single, the "can't return to the airport" time period is much longer.


Agreed, but the flight plan is predicated on the pilot being able to execute per the book. If he can't, you can't flight plan around that.

Singles handle off airport landings much better than twins (assuming typical speeds)

I agree the sim is a superb training tool. I was just surprised how easy it was to get in dicey situations with a legally operated 421.

This is true for any piston twin legal or not.

Not really true. Yes, an A36 would do better than a 421 in an off-field (no engines running) scenario, but only because it's a lot lighter and also has a slower stall speed.

While there will never be any data to back it up, I suspect twins of similar weight and similar stall speeds would handle an off airport landing just as well as a comparable single.

Other than the PC12, there simply isn't a single that's anywhere near comparable to a 421, so I think it's unfair to make it a single/twin issue.

That being said, you'll be in the weeds in any piston powered twin if you lose an engine at rotation, before the wheels come up, if you're at gross on a hot day. You'd end up there in a single as well.

That is even the case for many turbo-props.

I am doing 3 days initial in a full motion sim and then an additional 2 days by same instructor in the plane. Then another 25 plus hours of mentoring by our on-staff pilot....

So..... You bought one then?

Ummmm... this is a what if scenario [/quote]

Sure....
Right....
