The excuse when something goes (hopefully not horribly) wrong while the new trainee is sitting in position, trying to vector airplanes around the skies of Munich or bargain with adjacent sectors about the best way to transfer airplanes.
It has been used only once during an actual radio transmission by my coach so far (when telling a pilot to disregard his descent instruction as another plane was relatively close and was – not known to me – released to another controller), though a few other situations would probably have provided enough justification.
That said, apologies to the Condor pilots who were put on a vector for a straight-in approach (i.e., without the usual weaving and turning to get into the normal traffic pattern), but were then not descended accordingly, as there was another airplane in the way.
It probably caused some puzzled reactions in the cockpit to have to level off, and then being told that “you are a little too high for straight-in, turn left heading 340”. You might have been wondering what my plan was, or if I even had one, and you would have been fully justified.
It was “one of those days” anyways, days I also had back in the Sim (thankfully not that often), but which appear much scarier in real life (hopefully not that often).
Turning a police helicopter while he was still in someone else’s control zone, scratching another sector with an inbound turned too early (“München Approach South apologizes”), handing an airplane over too the next controller while it was way too high, and too fast (of course) – the safety net built into the system works well enough to prevent chaos and mayhem, but it’s things which add up and make such a day one to be put into the category “learned a lot, achieved little”.
It’s indeed “training in progress” (and, in case of anyone wondering, still fun!)
