- Chapter 7: Aircraft Systems › Anti-Ice and Deice Systems › Airfoil Anti-Ice and Deice
Proper maintenance and care of deicing boots are important for continued operation of this system. They need to be carefully inspected during preflight. Another type of leading edge protection is the thermal anti-ice system. Heat provides ... most effective methods for preventing ice accumulation on an airfoil. High performance turbine aircraft often direct hot air from the compressor section of the engine to the leading edge surfaces. The hot air heats the leading edge surfaces sufficiently…
- Chapter 18: Emergency Procedures › System Malfunctions › Pitot-Static System
Pitot-Static System The source of the pressure for operating the airspeed indicator, the vertical speed indicator (VSI), and the altimeter is the pitot-static system. The major components of the pitot-static system are the impact pressure chamber ... lines and the static pressure chamber and lines, each of which are subject to total or partial blockage by ice, dirt, and/or other foreign matter. Blockage of the pitot-static system adversely affects instrument operation. [Figure 18-10] Partial static…
- Chapter 7: Aircraft Systems › Chapter Summary
Other Anti-Ice and Deice Systems Pitot and static ports, fuel vents, stall-warning sensors, and other optional equipment may be heated by electrical elements. Operational checks of the electrically heated systems are to be checked in accordance with ... /POH. Operation of aircraft anti-icing and deicing systems should be checked prior to encountering icing conditions. Encounters with structural ice require immediate action. Anti-icing and deicing equipment are not intended to sustain long-term flight in icing conditions…
- Chapter 7: Aircraft Systems › Anti-Ice and Deice Systems › Propeller Anti-Ice
Propeller Anti-Ice Propellers are protected from icing by the use of alcohol or electrically heated elements. Some propellers are equipped with a discharge nozzle that is pointed toward the root of the blade. Alcohol is discharged from the nozzles ... leading edge of the blade. The boots are also grooved to help direct the flow of alcohol. This prevents ice from forming on the leading edge of the propeller. Propellers can also be fitted with propeller anti-ice boots…
- Chapter 8: Flight Instruments › Blocked Static System
Blocked Static System If the static system becomes blocked but the pitot tube remains clear, the ASI continues to operate; however, it is inaccurate. The airspeed indicates lower than the actual airspeed when the aircraft is operated above the altitude ... where the static ports became blocked because the trapped static pressure is higher than normal for that altitude. When operating at a lower altitude, a faster than actual airspeed is displayed due to the relatively low static pressure trapped…
- Chapter 3: Induction & Exhaust Systems › Basic Carburetor Induction System › Induction System Icing
Induction System Icing A short discussion concerning the formation and location of induction system ice is helpful, even though a technician is not normally concerned with operations that occur when the aircraft is in flight. [Figure 3-7] Technicians should ... know something about induction system icing because of its effect on engine performance and troubleshooting. Even when an inspection shows that everything is in proper working order and the engine performs perfectly on the ground, induction system ice can cause…
