Airbus direct law landing
Technique for direct law landings.
If you're in alternate law, lowering the gear puts you in direct law and auto trim is lost. So I think the technique is to fly the approach stabilised, landing flap, @Vapp (to get it all trimmed out nicely) and THEN lower the gear and no further trim changes should be necessary.
Is that the general technique? I notice the QRH for G+Y hydraulic specifically requests this for example, but struggling to find other examples.
