As far as TCAS is concerned, a pilot is expected to comply with an RA
unless he has better information (i.e. visual on the intruder aircraft).
He is also allowed to deviate from his assigned altitude to the extent
necessary to comply with the RA ( ussually only several hundred feet if
performed properly).
