When the Flight Compartment or Cabin Temperatures are in excess of 40°C, What is the ground operation
limitation of the DUs?
Operation of DUs for more than 30 minutes with Cabin Temperatures in excess of 40°C is prohibited.

400ft, then changes to FMS NAV/VNAV Modes (if transitioning from an ILS or FMS with VNAV approach). - Vertical: it maintains a pitch between 10°
and 20°up max in order to maintain target speed.
How is the TO Vertical Mode cleared?
By selecting another Vertical Mode.
