Flight Deck Door
The flight deck door must be kept closed at all times during flight, except to permit access and egress in accordance with the FOM and this CFM. Any time the flight deck door is opened during flight, a challenge and response closing and locking verification must be used to verify that the door is closed and locked. Any time one of the required Flight Crew leaves the flight deck, another Crewmember (Flight Attendant or Flight Observer) must be present in the flight deck to ensure the required Crewmember is not locked out.

Engine Cowl Anti-Ice, Ground Ops
The Cowl Anti-Ice system must be ON when:
-The OAT is 10°C or below and visible moisture is present in any form.
-The OAT is 10°C or below when operating on runways, ramps, or taxiways where surface snow, ice, standing water, or slush is present.
NOTE: The WING ANTI-ICE shall be selected ON prior to the COWL ANTI-ICE to prevent possible pressure spikes requiring maintenance action to reset the Cowl Anti-ice Pressure Relief Valve. If the WING ANTI-ICE is not needed, it can be selected OFF.  
Wing Anti-Ice, Ground Ops
The WING ANTI-ICE system must be on for takeoff when icing conditions exist on the ground, the OAT is 5oC or below, and:
-Visible moisture in any form (such as fog with visibility of 1 mile or less, rain, snow, sleet, and ice crystals) is present, or
-the runway is wet or contaminated with surface snow, slush or standing water.

-ICE is annuciated by the ice detection system
NOTE: The WING ANTI-ICE shall be selected ON prior to the COWL ANTI-ICE to prevent possible pressure spikes requiring maintenance action to reset the Cowl Anti-ice Pressure Relief Valve. If the WING ANTI-ICE is not needed, it can be selected OFF. Wing Anti-Ice The WING ANTI-ICE system must be on when:
-ICE is annunciated by the ice detection system
-in icing conditions and the airspeed is less than 230 KIAS.
Do not hold in icing conditions with the flaps/slats extended.
WARNING
-Delaying the use of cowl anti-ice may result in engine ice ingestion, resulting in possible severe engine damage and/or flameout.
-Delaying the use of wing anti-ice may result in small accumulations of ice on the wing leading edge. Even small accumulations on the wing leading edge can change stall characteristics, the stall speed, and the stall margin provided by the stall protection system.
Visible Moisture Definition:
Visible moisture includes clouds, fog with visibility of 1 mile (ground operations)[1,500 meters] or less, rain, snow, sleet, or ice crystals.

2. It is permitted to fly at Vy (best rate of climb) when specifically asked by ATC to maintain the best rate of climb, except in icing conditions above 15,000 ft.
3. If restrictd by an MEL, maintain the highest speed allowed by the MEL, but it is not permitted to fly slower than Vx.
