SYSTEMS PARTICULARITIES
1. The stabilizer is lost. In alternate law, the auto trim function is provided through the elevators. At landing gear extension, switching to direct law, the auto trim function is lost. However, the mean
elevator position at that time is memorized, and becomes the reference for centered sidestick position. This is why, in order to ensure proper centered sidestick position for approach and landing, the procedure requires to wait for stabilization at VAPP, before landing gear extension.
If this procedure is missed, the flare and pitch control in case of go-around may be difficult. The PFD message USE MAN PITCH TRIM after landing gear extension should thus be disregarded.

2. High pitch during approach should be expected. Approach briefing should outline it for tail strike awareness and pitch attitude will be monitored during flare.

LDG WITH ABNORMAL L/G
Applicable to: ALL
This situation might occur following completion of a L/G GEAR NOT DOWNLOCKED procedure. It is always better to land with any available gear rather than carry out a landing without any gear.
In all cases, weight should be reduced as much as possible to provide the slowest possible touchdown speed. Although foaming of the runway is not a requirement, full advantage should be taken of any ATC offer to do so.
The passengers and cabin crew should be informed of the situation in good time. This will allow the cabin crew to prepare the cabin and perform their emergency landing and evacuation procedures. If one or both main landing gears in abnormal position, the ground spoilers will not be armed to keep as much roll authority as possible for maintaining the wings level. Ground spoiler extension would prevent spoilers from acting as roll surfaces.
The crew will not arm the autobrake as manual braking will enable better pitch and roll control. Furthermore, with at least one main landing gear in the abnormal position, the autobrake cannot be activated (ground spoilers not armed).
With one main landing gear not extended, the reference speed used by the anti-skid system is not correctly initialized. Consequently, the anti-skid must be switched off to prevent permanent brake release.
