ICE AND RAIN PROTECTION - DESCRIPTION AND OPERATION
___________________________________________________
1. Ice Protection______________
A. General
(1) The anti-icing system ensures operation and control of airplane systems under ice conditions. The anti-icing system is made up of five subsystems: wing thermal anti-icing, engine inlet thermal anti-icing, probe anti-icing, flight compartment window anti-icing, and water and drain line heaters.
B. Component Details
(1)
Wing Thermal Anti-Icing (30-11-00)
(a) The wing thermal anti-icing system uses engine bleed air to prevent ice formation on the leading edge slats. System components include thermal anti-ice (TAI) valves, telescoping ducts, flexible couplings, spray tubes, wing and engine anti-ice control panel, and test panel.
(2)
Engine Inlet Thermal Anti-Icing (30-21-00)
(a) The engine inlet thermal anti-icing system uses engine bleed air to prevent ice formation on the engine inlet cowls. Engine P1 probes are electrically heated. System components include engine inlet thermal anti-ice (TAI) valves, engine inlet TAI pressure switches, engine inlet cowl ducts, engine P1 probes, and wing and engine anti-ice control panel.
(3)
Probe Anti-Icing:
(a)
Pitot Probe Anti-Icing (30-31-00)
1) Pitot probes are electrically heated to prevent erroneous readings due to ice formation. System components are pitot probes, the test panel, and the annunciator panel.
(b)
Angle of Attack Probe Heat (30-32-00)
1) Angle of attack probes are electrically heated to prevent erroneous readings due to ice formation. System components are angle of attack probes, the test panel, and the annunciator panel. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：757 AMM 飞机维护手册 防冰和排雨 CHAPTER 30 - ICE AND RAIN PROTECTION(5)
