Atr 72/ Atr 42

I would be most gratefull if someone who flys on the ATR 72 and ATR 42, who has a type rating could answer the following questions.

Does ATR 72 land with power on? what is the Torque/ ITT/N1 meant to be at touchdown.

Does ATR 42 land with power on? what is the Torque/ ITT/N1 meant to be at touchdown.

I would be most gratefull if someone could answer this question for me please.

About 20-30% torque and you can land with this power or just retard the throttle 20 fts. AGL. It is up to you.

Is there any specific information relating to ITT/ engine torque/ n1 in the POH relating to these aircraft this under 20ft RA or 5ft RA.

I would be most gratefull if someone could answer this for both ATR 72 & ATR 42.

It's written in the FCOM that you cut the power at 20 ft and flare. Same for both the 42 and 72.
But, in practice, as pamudiro said, you may want to keep some power until touchdown. It depends on the landing weight, the wind, normal/icing speeds...
You'll probably get more answers if you ask in the "tech log" section.

You have indication of torque-ITT-Nh-Nl but you usually only check during the approach your torque. If there is a lot of wind or you land over 21500 Kgs. you will have to set up to 35% torque. You can check it on procedures and technics.
I do not about the ATR42 because I only fly the 72-500.

Hey, on the subject of ATR, i assume some of you guys are flight crew on the aircraft. I am recently qualified on the ATR 42/72 and i am looking for my first airline job. Any ideas?

Most aircraft have a section in the SOPM that states something like "At nn feet Radio Altitude, reduce power to Idle." Certainly, the five aircraft I have on my licence all insist power is brought to idle; the height varying from 50' to 30'. But be very wary of hot shots telling you to leave power on if the manual states otherwise. I've flown with some of these plonkers and gobbled up runway like it's going out of fashion. As ever though, your manual will state the appropriate technique.

I do not know if you actually fly the ATR. I have more than 6000 hours on it and in my company there are many pilots that land with at least 20% torque. I know that the SOP of the ATR say you have to set idle at 20 fts. but if you land very heavy or with a lot of head wind it is better to land with some power on you enginees.
It is just my opinion.

Dude, 20 ft power idle. no other techniques allowed.
And don't flare too much, coz it'll become very unstable on directional control, and the idle gate gate won't pop. Be solid on your landings and be decisive with ailerons twd the wind. (ATR 42MP xprience.)
write me if u have more questions.

The most important is to have the correct IAS and rate of descent. Beforehand pilots have to feel their aircraft, really. You may just gently reduce PLs to Flight Idle until you touchdown. Bear in mind that the flight manuals are just theory, they are a guide, but there is often a little gap between theory and practice, especially when we talk about flying.

aaron wilmott, are you still looking for a job? Best of luck if you do so.

Thanks for the kind words HotelModeMetar.Still looking im sorry to say.
What you said is correct, like landing any aircraft, factors change e.g wind gusts, runway slopes, glide path angle. But nail the IAS and ROD and usually the published method wont leave your passengers in too much discomfort,

4 blades vs 6 blades

i think the best answer come from hotelmodemetar at 20 fts you should gently decrease your pl's to flight idle .
In fact the big difference is not between 42 and 72 but between 300 (4 blades) and 500 ( 6 blades)
if you move too fast pl's to flight idle with 4 blades you ll not decelerate too much but with 6 blades youll feel a strong deceleration when your Tq will go under 15%
then if you flare a little bit high with your exact Vref you have 99% risk to perform a nice boom landing with 500 series.
it depends also on how long is your runway

About ATR 72 500. Very important to keep the correct speed. Torque depends on weight. It ranges between 16 to 21 psi. Better to land with some power, otherwise quite hard touch down. Very little flare, just to keep the nose wheel out of the ground. I land this way even on short runways, about 1400 m long. Careful during ground roll: very nervous.
Happy landings
