Powerpush

(1/3) > >>

EHM-1001 Robert:
Hi mates,

I red it somewhere that there is not only Pushback, but also Powerpush. Here, a tractor pushes one of the main gears, while the crew is steering the aircraft. Although I cant imagine why is it better than pushback...

Any ideas ?

EHM-1651 Christian:
You won't have to remove the pin or struts to the nose wheel steering on the nose landinggear, that way saving some time on pushback connecting and reconecting that system to the nose gear. That is the only advantage I can think of.

EHM-1001 Robert:
I thought maybe because of noise restrictions. Also it may depend on where the aircraft nose is pointing. Although I still do not know an airport where it was used...

EHM-1651 Christian:
The powerpush term is also used when aircraft perfrom pushback using their own enginepower, the DC-9's adn MD-80's were certifed for that aswell as ATR's.

EHM-1001 Robert:
Well, by push I really meant a push forward :) So I seen a picture where the push tractor pushes the main gear strut from behind, and the stupid guys up in the cockpit were playing with the nosewheel to keep the baby in direction :P

I heard (maybe here) some powerful turboprops can make a pushback from the gate with "reversed thrust" setting of feathers. That could be strange though, I would like to see one ;D
