When are reduced NP landings prohibited?
•Reduced NP landings are prohibited when:
- Landings are accomplished at the Solid Bug – VREF (ICE).
- Performance requires Bleeds OFF.
- Tailwind component exceeds ten knots.
- Windshear is reported or suspected.
- Runway is contaminated or braking action is less than good.
- Landing performance is derived from the Emergency and Abnormal Checklist manual section 15, Adjusted Landing Speed and Distance Tables.

FSM 1.4.6
What is the definition of Icing conditions?
Definition of Icing Conditions:
Icing conditions exist when:
• On the ground (taxi and takeoff roll to the point of lift-off): SAT is 10°C or below when precipitation in any form is present, or fog with visibility of one mile or less; also when operating on ramps, taxiways, or runways where surface snow, ice, slush, or standing water may be ingested by the engines or freeze on engines, nacelles, or engine sensor probes. M
• In flight (after lift-off to landing): SAT is 5°C or below and visible moisture is present in any form. Ice accretion on aerodynamic surfaces is not considered to exist at temperatures of -40°C or below. M
FSM1.5.1
Below what temperature is ice accretion not considered to exist?
-40 degrees C
After exiting icing conditions, when is the aircraft considered aerodynamically clean?
The aircraft can only be considered aerodynamically clean when all ice is removed from the visible leading edges and wingtips.
FSM 8.5.2
What is the minimum speed in severe icing conditions?
200 KIAS
FSM 1.3.1
What is the maximum crosswind component for takeoff or landing?
32 Knots
What is the maximum tailwind component for takeoff or landing?
20 Knots
When are the tank aux pumps required to be on?
Take off and landing
When is the autopilot prohibited from being used?
Autopilot Engagement After takeoff or go-around, the minimum height for autopilot engagement is 1,000 feet AFE.
• Autopilot shall be disengaged at or above 1,000 feet AFE for the following approaches:
- HGS flown in AIII mode
- inoperative engine
- Flap 0°
• For coupled approaches, the autopilot shall be disengaged at or above 200 feet AFE.
• Autopilot shall be disengaged in severe icing.
• Autopilot shall be disengaged in severe or extreme atmospheric conditions.
