We do not have a holding bay at the threshold of our dep RWY and from GMC we "try" and presquence acft on the pushback so that they will taxi in a semi decent departure order as once acft are in the lane the order they are pushed is the order that they will depart unless we use intersection departures (tell us on push if you can) so the call
"Ground, we have problem, will call you back again ready to push"
can really @*3! the plan you had but
RATHER DO THIS THAN NOT PUSH cause you will just back log the entire system. I can make a new plan if neccesary that is the whole idea why they train us. But a point to remember that this could have delayed someone on the same SID that was now told to stby for sequencing.
As far as having camera's I think that the time it would take to look at that having to select correct feed etc is probable about the same time as it takes to ask Confirm you are pushing. If they don't come back with an answer or say afirm and don't move within 15sec after that I'll cancel the push if I need the lane behind and then acft goes at back of start queue.
Unfortunetly especially during ATC delays due FLOW that often when you are now ready to push an acft that the Tug has dissapeared cause the handling agent thinks that another acft is going to get push. When there are delays like this (excess 30 min) ussually when I see that I will push an acft shortly I'll tell them expect push in 3min etc gives the crew time to check that the tugs still there and they can wake up the driver etc. (I'm not that good that 3min is exact its just a guess so that the ball gets rolling and we don't have a situation where the tugs on another acft)
