Why Use Reverse Thrust To Push Back?

Tue Jul 23, 2002 7:35 am

Hi!

I was just browsing for aircrafts that uses their reverse thrusters to slow themselves down after landing.

Halfway through my search, I found this:

Why in the world do some airports allow this instead of the push-back tractor, and in what factors allow a/craft pushback using reverse thrusters??

Confused...

Only aircraft with rear-mounted engines push themselves back for safety reasons. If a tug isn't available a plane can push itself back, if there's room of course.

The main reason for "Power Backs" is money. Why pay for 3 men to push a plane back when you can just use 1 man as a lookout and back the plane up using reverse thrust! Anyways, I know US Airways has Union rules against this practice but AirTran has obviously done something right! Think about it! 3 Workers to 1, plus the operating cost of the Tug. Anyways thats the main reason.

Some airlines do powerbacks (the term for using the thrust reversers in this manner) in order to speed up turnaround times, and also so they do not have to spend the time and money buying as many pushback units and training ramp personnel to pushback aircraft. Not all airports allow powerbacks, ATL does because there is enough space on the ramp areas between the concourses to do this proceedure safely. AirTran is not the only airline that does it @ ATL. I have seen Northwest do it with their DC-9s and 727s, United with their 727s and American with their 727s. Some airlines don't do powerbacks because it does put extra strain on the engines, and in turn, increases the MX costs. Nearly every jet aircraft can be powerbacked, even those with wing mounted engines, but most airlines wouldn't dare to with a wing mounted engine, because of the increased FOD risk.

AA MD-80s do it ALL the time at DFW. It is a more exciting way of starting off a trip I think!

AA used to do it with their 727s as well.

ATCT, actually AirTran does use three people when they do a powerback. A marshaller and two wingwalkers. I did my share of powerbacks in my days @ AirTran, and the only airline I saw that didn't use two wingwalkers on a powerback was NW.
