Outsiders comment: I can imagine that there is an agreement that a/c will only request 'push' when they are ready? It might be at the bottom of half a ton of paper contracts but it'll be there somewhere! If it does ...
If a/c requests push and does not move within ... 90 seconds?? then the details just get noted back to the carrier. No penalties or inquiries - just Name and a/c number.
If that happens too many times, then carrier bosses are going to know. As I say, don't make a fuss just report them as being out of order. If it happens to the point where a particular carrier is cropping up on the lists and still does nothing, then it might be time to talk money.
Given that we hear that all airports are being hurried and harried for greater efficiency, waiting four minutes for someone who is taking advantage of the rules, has to be stopped.
If no such agreement exists, then ATC bosses should be asked to invent one, so as to improve timely departure of all a/c.
Before flight crew tell me to bog off:
I can well understand that some crew get used to particular ways of handling at other fields in other countries. But LateLandingClearance is obviously talking about the UK. OK, now tell me that I know nothing about time-keeping and management checking the sheets every day to see if you dropped a minute and I'll tell you about 23 years in commerce with an increasing army of managers breathing down my neck. At times I have been that manager! We are not talking airmanship here, otherwise I would not speak in this manner.
