A MESSAGE TO FLIGHT CREWS FROM THE BOEING COMMERCIAL AIRPLANE GROUP
Aircraft Applicability: 737, 747, 757, 767, 777
Reference Number: 737-29, 747-29, 757-25, 767-25, 777-02
Options are available on all Boeing aircraft to inhibit early glideslope capture. Glideslope deviation and localiser deviation indications are always available on both pilot's flight displays for all FCC options.
Whether EFIS-equipped or not, there may be legitimate and valid reasons for an early glideslope capture capability to cope with ATC altitude clearances. Its use is safe and effective provided proper situational awareness is employed in the decision to exercise early glideslope capture. Specific situational awareness should be part of any decision to intentionally capture glideslope early. Pilots should be aware of the inherent risks associated with performing early glideslope capture if not properly aligned on the localiser course.
