Expedite mode
It was a very stupid feature. I did not like to use it. During "expedite" the rate of climb would take off and the speed would drop below what I consider a safe amount. It was also removed from the 330.
Speed is very important when climbing at high altitudes. Rate of climb should not be for climb as it causes the speed to slowly fall and as a result the wing looses lift. It's airflow that produces lift so airspeed is important. I thought that AB would have replaced the expedite mode on the 320 also but..............
