Recently Ive noticed this occurring more and more. An ATC controller will hop on Ground and Tower and get requests to push back and taxi and will hold everyone for at least 15-20 mins. Most people (like me) comply with the freeze, others leave out of frustration. The worst thing is that after all that waiting the ATC will say that they are changing controllers and they leave. This begins the frenzy as all pilots that were waiting, scramble to get moving before another controller hops on in fear that they will have to wait even longer.
A few days ago, Monday or Tuesday I believe…was the most recent time this happened while I was on. I understand the airport may be busy but I made sure to check that it wasnt. 3 inbound aircrafts, 5 grounded but by the time the controller left, we had 14 grounded, 7 inbound.
My reason for posting this is to find out why this happens and if it is something that is supposed to happen.
