RW2 for aircraft parking
I would think parking aircraft on RW2 is more trouble than its worth, what happens if you have a closure of RW1 for whatever reason. It would take a long time to shift a row of aircraft. Also carrying out ongoing servicing of the runway surface would be impossible, also long term parking of heavy leaking aircraft may actually cause damage to the runway. And lastly carrying out storage service routines on the aircraft would be difficult as its part of the runway and taxiway system, very few people are permitted or qualified to drive there.
