Ice protection system
Content
Icing conditions
Hot air anti-icing
Electrical anti-icing
Performance impacts

Icing conditions
•Generally from OAT - 40 °C to slightly positive °C (rarely below -12°C)
•In terms of altitude : icing conditions à Around FL100 down to the ground
•Icing conditions also depends on aircraft speed  

Two anti-ice protections•For anti-icing, critical areas protected by :
– Hot air from engines
– Or electrical heating

Hydraulic system

Content  
Description
Controls & monitoring
Abnormal operations
  
Purpose and use
•Fly by wire : Pilot orders à Electric
Controls actuation à The power is always hydraulic.
•The hydraulic system is designed to provide the power to actuate the :
–Flight controls (flaps, slats, rudder…),
–Landing gear,
–Brakes.

•Fully automatic during normal operations
à No action is required during all flight’s phases
•   3 hydraulic systems : green, yellow and blue systems
  Description : Green and Yellow systems

•Each system has its own reservoir.
•GREEN & YELLOW hydraulic systems :
Each pressurized by an engine driven pump.   
•Hydraulic fluid cannot be transferred from one system to another :
The systems are fully independent to isolate a leak of one system.
