Mmo may be easily exceeded when descending
from high altitude. The pilot should frequently
cross check the airspeed and Mach limit indicators
to avoid exceeding Mmo. Exceeding Mmo could
result in structural failure and loss of airframe
1. CABIN CONTROLLER - Set.
2. ICE & RAIN switches - As required.
3. WINDSHIELD anti-ice - As required.
Set windshield anti-ice to NORMAL or HIGH as
required well before descent into icing conditions
or into warm moist air to aid in defogging. Turn off
windshield anti-ice when descent is completed to
lower altitudes and when heating is no longer
required. This will preclude possible wind screen

Altimeters - Set to current altimeter setting
