I have another question.
Last time I operated out of HKG we requested our clearance from ATC, after switching to ground control we requested start and push and were advised to stand by. Not a problem at all and this happens at most other airports around the globe as well.
After a couple of minutes we called ground control again, stating that we were still standing by for start and push and we received the same response from the ground controller as before. After another couple of minutes we called ground again and asked again for start and push and received the same response as previously. We then asked the controlled to state the reason for the delay, we received the replay „due to traffic“. We then further querried from ground the estimated delay and received no definite answer.
To make it short our next request was „succesfull“ and we were instructed to push and start up. We also received our taxi instruction for the active runway. Approaching the holding position the tower controller informed us to expect 15 minutes delay due to airspace restictions. Here we go.
I ask myself why didn’t neither delivery nor ground informed us accordingly? This would have saved a lot of dicussion on the frequency as well a considerable amount of the more and more expensive liquid used to „flood“ our engines. By the way, we were perfectly on time according to our ATC flightplan.
