What if we declare via NOTAM/ AIP that such aircraft as A321, A320, ATR-72 may cross the THR of the runway-in-use while there is a traffic approaching & landing on Dis.THR?
Jeeesus ! are you serious ? and are you Vietnam management ?
If you really intend to do that do not ask permission to do this on PPruNe, ask the ICAO Bangkok office.
