You haven’t lived until Teterboro clearance tells you don’t call me, I’ll call you to start engines. Which is the beginning of a great Charlie Foxtrot between crews trying to convince the controller to move them up in the line because they’ll run out of duty with an EDCT like that. Then the no GPU/ APU crowd chimes in and says they can’t keep the power on to listen for their clearance, so they’ll check back in a few minutes “Hey clearance, this is citation N123AB, I had the batteries off, did you call us?” The finale is when clearance calls for someone to start engines, then that airplane responds with “We haven’t been fueled yet.” and ATC tells them that they’ll go back to the bottom of the queue. Now that crew very angrily calls the FBO on the radio and asks where is the fuel truck?
