Now that the 330 is the topic of discussion here can someone plz enlighten me as to why on the 330 are there 2 buttons namely the ALT Button (in place of EXPED) on the 320 and the Push to level off/ VS button on the FCU there for exactly the same function ,
and correct me if I'm wrong new airbus trg policy now teaches the crew to hit the push to level off and Not the alt button in the event of a need to level off ?
all thoughts welcome
