Hello,
sorry, but you have allways a little error in your pushback sequence.
After the Truck is connected and the Pin is installed the Pushback Man has to wait until he Captain contacts him and say "Ready for Push". After that the Pushback Man says "release Brakes please" !!
Also after the pushback is finished, the Pushback man says "Set Brakes please", the thea lift down the airplane and wait until the Captain says "All ok, remove Towing system, handsignal on the right/left hand site please .. bye". after that signal from the Captain the Pushback Man is allowed to disconnect all not before.
Thats for the case one engine is not running correct and the airplane mus go back into the Position for a check.
And one last thing...with left and right direction of the pushback it means normaly the nose. So it is always better to say what you mean, nose or tail left/right, not only left or rigth. always we have to say "Nose right/left" or "Tail right/left".
It will be better to have this ( nose or tail ) in the litle window where i have to select left or right direction of the pushback.
