Re: Why not measure acceleration instead of using derated flat throttle percentage?

FBW Airbus do compute the gross weight, although only after the aircraft is in the air. If the difference between the entered GW in the FMS and the computed GW is higher than 7 tonnes, an amber ECAM alert „CHECK GW“ will show in the cockpit. This is calculated via the flight computers using data fro...
