Engine Anti-Ice Valve

30-21-01BEngine Anti-Ice Valve
Applicable to: -
- General information
An higher idle speed is set on both engines when an engine anti-ice valve is inoperative in the open position.
- Flight preparation/limitations
Note:
  1. The following decrements may be used for takeoff performance determination only for dry runways if no takeoff data (predetermined by using OCTOPUS program or other equivalent program with present failure case taken into account) is available.
  2. Performance penalties apply whatever one or both valves are inoperative.
Takeoff performance:
Perform the takeoff using full thrust.
Apply the following reductions on the MTOW and the speeds :
OAT (°C)
≤ ISA +10 °C
> ISA +10 °C
