Question for any ATR pilots out there...

[abaile]

I need to know what the single-engine approach procedures are for the ATR for one of my classes. I can't find it anywhere so I figured I'd ask on here and hope an ATR pilot stumbles upon. I really just need to know flap setting, approach speed, and any immerdiate action items. If anyone could tell me I'd appreciate it. Thanks.

Not a big deal at all. Do everything like normal. You have MCT on the operating engine and max rpm as well. The only difference is on approach the operative bleed goes off and there is a note.......minimum sigle engine approach speed is 89 knots . Thats it. Otherwise same same.

Thanks alot for the repsonse. One other thing, what flap setting would you use? And do you always fly the minimum single engine approach speed or does it usually end up higher then 89 knots?

MCT on the operating engine

That stands for "Must Commute Today" doesn't it?

Landing would be at flaps 30. I don't think I've ever seen the ATR at 89 knots. It'll do it but it's real sluggish. Landing weights at 36K ( I think max is 36160) would be V0-133 V15-114 Vref-103.....in any case our target was always 120 in non-icing and no wind additive. The book says to be over the numbers at ref(ish) but most guys flew 110-120 until the flare and it set down real nice. Since our speeds were pushed up so much higher than what it really needed for aerodynamics the single engine approach and landing was no big deal. These are based on CALEX procedures and my memory from 2+ years ago.

Or my connections tight!!!!

On the -72 our single engine ILS procedure is exactly the same as dual engine, except minimum approach speed is 112 kts. Flaps 30, same as normal. On non precision the speeds are the same, but we don't go from flaps 15 to flaps 30 until landing is assured. The 112 speed usually won't even become a factor until you are really light, and at most speed cards (37,000-45,000) you are going to be about 120 or so until over the fence.
