G+B Failure
Extend the landing gear at 200 kt to revert
sooner in direct law. This provides, below 200 kt
, a better pitch control than in alternate law with
one elevator lost and all slats lost.
G+Y Failure
Being stabilized at VAPP, before
selecting the gear down, enables the aircraft to
be trimmed for approach.
Both notes are in the QRH and ABN PRO 29.
