Chapter 15: Ice & Rain Protection › Rain Control Systems › Windshield Wiper Systems
Rain Control Systems There are several different ways to remove the rain from the windshields. Most aircraft use one or a combination of the following systems: windshield wipers, chemical rain repellent, pneumatic rain removal (jet blast), or windshields treated with ... hydrophobic surface seal coating. Windshield Wiper Systems In an electrical windshield wiper system, the wiper blades are driven by an electric motor(s) that receive (s) power from the aircraft’s electrical system. On some aircraft, the pilot…

Whether resistance wires or a laminated conductive film is used, aircraft window heat systems have transformers to supply power and feedback mechanisms, such as thermistors, to provide a window heat control ... unit with information used to keep operating temperature within acceptable limits. Some systems are automatic while others are controlled by flight deck switches. Separate circuits for pilot and co-pilot are common to ensure visibility in case of a malfunction…

modern aircraft, many of these systems are automatically controlled by the ice detection system and onboard computers. Figure 15-3. Ice and rain protection systems. Figure 15-4. An ice detector alerts the flight crew of icing conditions ... some aircraft, automatically activates ice protection systems. One or more detectors are located on the forward fuselage. Ice Detector System Ice can be detected visually, but most modern aircraft have one or more ice detector sensors that warn the flight…

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…
