View Full Version : Backing an aircraft
Read recently that an aircraft can be backed out of a loading bay using its own engines. How is this done?

Some aircraft are certificated for use of reversers at low speed for self push-back etc.
Generally to be avoided because of exhaust gas re-circulation, debris ingestion etc..
Same applies for using beta control on propellers.

If you want to have real fun the power back is the perfect moment to hit the brakes.
I saw a Northwest DC-9 do this at MSP a few months back. It just didn't seem right and prior to this I thought it was more or less confined to operations in some rather less well regulated parts of the world.
I do seem to recall hearing of an Aeroflot IL-62 damaging equipment/buildings using this technique. Can anyone fill in the details?

Jetstreams (both 31 and 41) and ATP's are very easy to reverse out. British Regional do it all the time @ BHD.
The ATR can also power-back, but it's less recommended. My company's Ops Manual doesn't permit it at all.

Hugmonster,
That must've been a fairly recent additionto the ops manual as in the past we did it quite frequently.
I often see an American Airlines 727 reversing off stand in Washington. Lots of smoke, dust, debris etc. Looks quite impressive.

Did a 'three point turn' in a VC10 at Blantyre, Malawi, in 1968. The runway was only 100ft wide and we misjudged the turn.

The C-17 Globemaster is certified to do this: quote: "The unique thrust reverser design allows the BC-17X to back up a 2% slope fully loaded, making parking and operating at small, austere or congested airports easy. Tugs and tow bars are not required."
