We had some problems with over rotation in my current company when we started to use mix fleet.Our flight data and analysis group sent some numbers of letters regarding over rotation during take off on the NEO planes particularly with maximum TOW and high OAT.
Some times later our flight department sent a letter with recommendations to carry out all take offs on the NEO fleet with F-2 only!
Since EFB calculations offers F-2/3 only
Safe flights
