OBIO, an other (more thrilling) way to perform this manoeuvre is to set the reversers (DASH7, Hercules, Twin Otter) and then apply differential braking (F11, F12 keys).
I once saw this 'power-pushback' IRL with an ATR at Fuerteventura - looks frightening!
You just have to be careful applying full brakes when switching back from reverse to idle...![]()

Yep - it saw this once with a USAF C-17 at Berlin ILA. Very impressive aerobatics performance, this monster sure can take some G's! When clearing the runway, she just took the next taxiway creeping backwards into it.As for real life I have seen the Reverse Prop operation done many times..and a couple with jets when a tug was not available.
Here's a 'Pushback' gauge that can be installed with L & R turning.

[SIZE=-1] FS2004 Gauges--Pushback, Taxispeed Control, etc. This archive contains v4.0 of the "ground handling" gauges, like automated pushback with conversation sounds, a taxi speed controller using throttle and brake settings, an arming switch that activates taxispeed after a landing (including setting flaps, spoilers, autobrakes off), brakes sound, etc., and can be added to any FS2004 aircraft panel. New in v4.0: 1. Better sound mechanism (using Doug Dawsons XMLsound gauge), with advantages: individually adjustable sound volumes; no more "mis-use" of the ADF1 frequency, so no more sound on/off function needed. 2. Reworked bitmaps and code. 3. State-dependant tooltips. 4. Straight pushback before turn is now in meters instead of seconds. By Rob Barendregt. (Previous version had 5749 downloads.)![]()
