Sometimes, the six P's can be put to good use, when required.
A couple of months ago, the tug driver comes up and announces...'my headset doesn't work, do you have an objection?'
I mention to the guy...
'Hand signals work fine for me, I'll flash the taxi light, one for start, two for stop...and I think we have done this before, have we not?'
He says...'yes, we have, thanks Captain' and the resultant pushback works quite OK.
PS:
6 P's.
Prior Planning Prevents Pi** Poor Performance.
