2-5 mins, both 90 and 94 got this frequency
But aft 1700, frequency was quite horrible... Otherthan ADDs, if
the entrance is at the taxiway, the bus stop opp AFM should only be
used for alighting and os AFM bus stop, 2 seperate queues should be
made for 90 and 94 to prevent what happened in 2003 to repeat
