As you know one of today’s focus airports on the expert server is HAAB. HAAB as 2 runways, however one of the runways is used as a taxiway. So for example right now at HAAB, you will be given taxi instructions to 07R as 07L is being used as a taxiway. So, when you are given taxi instructions to 07R, please hold short of 07L and contact Tower, Tower will then give you a “Back Taxi and contact ground when you exit” instructions. Then Back taxi 07L towards 07R. There may be a line on 07L and thats ok. Stay on Tower frequency the whole time and do not switch to ground. You will then be given permission to take off from 07R when you are cleared to do so.
