Standing TRTs- Do Civilian Airlines Practice It?

Sat Feb 27, 2010 11:02 pm

In the C-5, we practice standing trt takeoffs when we are heavyweight, but have never seen or heard of airlines doing them. Do they?

I haven't seen a civilian airliner doing them exactly like in Fred; I'm pretty sure the controllers at JFK would be a little ticked by someone spending an extra 25 sec on the runway with engines at TRT. Although on really short runways like LGA, I've seen various implementations of the 'standing' technique in civilian airplanes (although I don't think the power is all the way up at brake release). When I was flying Part 121, we only had a "reduced" or "Max" thrust takeoff options, with flaps at either 10 or 20. They were both performed in the same way--you'd hold the brakes while running the EPRs up to about 1.1 and then release the brakes as you push the thrust levers up.

Anyone using Burbank Runway 33 on a cloudy day, when you can't see the mountans. They know the mountans are there and want as much speed and allttude as soon as they can get it. I've seem them make left hand turns as soon as the wheels clear the runway.

The only time we do a static run up is when there is a potential for fan icing. Otherwise we prefer to either keep rolling around the corner or release the brakes and then stand the power up.

Not very often. KSNA is the only place I do one regularly.

Let's not forget the fuel waste as well as the potential for airflow disruption when you're not moving and there's a bit of a crosswind.
