It's interesting to note that the performance chapter for the A320 bases all the figures on a MAC of 33%. Seems to me that if you start off with a MAC of34%, the fuel burn will cause the MAC to decrease during the flight towards a lower number, say about 30% depending on the length of the flight. This will keep the MAC close to the book value of 33%. Since the performance figures are based on 33%, wouldn't it make sense to load the airplane to reflect this value?
Seems not many ops people, chief pilots etc pay much attention to this area.
Any comments?
