Parking position
Please make sure you choose an appropriate stand for your aircraft type.
Passenger flights use parking positions on the Northeastern apron (all A-, B-, C-, and D-stands).
Passenger aircraft with a wingspan of more than 36 m should only park at A- and B-stands. Parking at C- and D-stands with these aircraft will most likely result in additional delay during periods of high traffic as your pushback will cause a "traffic jam" for other pilots.
Cargo flights use parking positions on the central apron (all E-, F-, and W-stands).
General aviation aircraft use the GA apron at hangars I, II, and III.
Military traffic uses the military apron located East of runway 14R/32L.
Communication
Complex instructions
As space is at a premium on Köln/Bonn's apron and controllers have to find creative solutions to avoid delays, you may well encounter instructions that you are unable to comply with. This doesn't even have to be a lack of skill on your part: sometimes your simulator simply doesn't have the functionality required.
If you receive an instruction that you are unable to comply with for any reason, hold position and inform ATC immediately!
If you are unsure what the controller wants you to do, hold position and inform ATC immediately. Not doing so will most likely result in you doing something else than ATC expects, thus causing major problems and delays; on the other hand, controllers have no problem with you asking for an explanation or a different instruction.
Handoffs
When instructed to contact another controller, do so as soon as possible. This will avoid you having to stop moving or level off. Please do not hold your position to switch the frequency, keep moving on the ground!
Colored lines
Parts of the Northwestern apron utilize colored taxiway lines which allow for more efficient taxi operations with aircraft up to a wingspan of 36 meters.
If ATC instructs you to use one of these colored lines, but they are missing from your scenery, hold position and inform ATC immediately.
