Flight Crew TrainingFlight Crew Training

T i i f fli ht t iTraining for flight crews current in B737-600/-700/-800/-900 aircraft is established at Level A..GLS approach procedures and techniques are identical to those of ILS (with 2 minor exceptions):of ILS (with 2 minor exceptions):

ILS uses a radio frequency whereas the GLS is a channel on the MMR. The navigation reference on the PFD say “GLS” instead of “ILS”.

Crew actions while flying a GLSCrew actions while flying a GLS approach are the same as those for an ILS approach.
