System Impacts

  • Auto mode of WAI is prohibited.

  • Maximum Airspeed for wing anti-ice operations is 0.85M.

  • Maximum Altitude for Wing Anti-Ice is 32,000 feet.

  • Maximum Altitude for Single Pack Operations is 48,000 feet.

  • Wing anti-ice operation is restricted to single ECS pack operations.

Corrective Action

  1. In Flight

    1. ENG BLEED AIR (Affected Engine) . . . OFF

    2. WAI . . . Deselect Auto

    3. If dual ECS pack operations are desired:

    4. (1) Isolation Valve . . . Open (Depressed)

      NOTE

      If the operating BAS displays abnormal indications, consider operation in a single ECS pack configuration to stabilize the BAS system.

      (2) Two ECS Pack Operation . . . Monitor

    5. If Wing Anti-Ice is required:

    6. (1) Altitude . . . Descend below 32,000 feet

      (2) Airspeed . . . 0.85M maximum

      (3) ECS Pack (Affected Engine) . . . OFF

      (4) Isolation Valve . . . Closed (Out)

      CAUTION

      WAI MUST BE ACTIVATED AND REACH AN OPERATING TEMPERATURE GREATER THAN 100°F PRIOR TO ENTRY INTO ICING CONDITIONS.

      (5) WAI . . . ON

      (6) ECS System . . . Monitor

  2. On Ground

    1. Dispatch . . . Reference MMEL
