  13. Engine Anti-Ice Use

    Icing conditions
    • Engine anti-ice must be on during all ground and flight operations when icing
    • conditions exist or are anticipated,

    Except during climb and cruise when the temperature is below - 40°C SAT.

    • Engine anti-ice must be on prior to and during descent in icing conditions, including
    • temperatures below - 40°C SAT.

    Engine ignition must be on when operating in icing conditions.

  14. Alternate Flaps
    Alternate Flap Duty Cycle

    When extending or retracting with the ALTERNATE FLAPS position switch, allow 15 SECONDS after releasing the ALTERNATE FLAPS position switch before moving the switch again to avoid damage to the alternate flap motor clutch.

    • After a complete extend/retract cycle. e.g., 0 to 15 and back to 0, allow 5 MINUTES
    • cooling before attempting another extension.
  15. Speed brakes limits
    • Do not deploy the speed brakes in flight at radio altitudes less than 1000 AFL

  17. Fuel Loading

    Ballast Fuel
    Main tanks 1 and 2 must be full if center tank contains more than 1000 lbs.

    Ballast fuel is not authorized.
  18. Fuel Imbalance
    Lateral imbalance between main tanks 1 and 2 must be scheduled to be zero.

    Random or transient fuel imbalance must not exceed 1000 lbs for taxi, takeoff, flight or landing
