Try and keep it simple
1. Do not use autoland under NORMAL circumstances when overweight for NORMAL operations. Use down to 500' aal and then amaze youself with your advanced flying ability to land the aircraft MANUALLY.
2. In an ABNORMAL situation all bets are off. Use the aircraft systems to your advantage as you see fit to achieve a SAFE result using best CRM and crew technical knowledge.
3. Know which limits apply to the particular Airbus you fly. Comparing A330/340 FCOM with early FMS1 A320 is apples and oranges. Just because a brand new Renault Megane has active lane control and intelligent airbags doesnt mean a 25 year old one will have!!
