Guys , 737s and ATPs reversing around the a/d approved , only proviso feet under the rudder pedals / brakes . Stop using forward thrust . Off a pier /stand with marshaller , around the a/d not necessary . 75's I honestly cannot remember any prohibitations . Reversed ATPs down runways to avoid ground manoeuvring tailwind limits .
3rd world ..E.Med , Africa , India have used rev. to get out of trouble on a Tristar.
In Amsterdam down some of the bridges in Icy conditions , even a Trident can be steered and braked with reverse ; when the brakes [ inc. Maxaret anti-skid ] and steering were useless .
Have used rev. on 744 on one side to tighten a turn on limiting width rwys . Cannot remember limitations 'tho ; well retired .
