Chapter 3. ICING EFFECTS, PROTECTION, AND DETECTION › 3-1. FORMS OF ICING › a. Structural Icing
Chapter 3. ICING EFFECTS, PROTECTION, AND DETECTION 3-1. FORMS OF ICING. Aircraft icing in flight is usually classified as being either structural icing or induction icing. Structural icing refers to the ice that forms on aircraft surfaces and components ... induction icing refers to ice in the engine’s induction system. a. Structural Icing. Ice forms on aircraft structures and surfaces when supercooled droplets adhere to them and freeze. Small and/or narrow objects are the best collectors of drops…

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 6: Flight Controls › Flight Control Systems › Primary Flight Controls
Flight Control Systems Flight Controls Aircraft flight control systems consist of primary and secondary systems. The ailerons, elevator (or stabilator), and rudder constitute the primary control system and are required to control an aircraft safely during flight. Wing flaps, leading ... edge devices, spoilers, and trim systems constitute the secondary control system and improve the performance characteristics of the airplane or relieve the pilot of excessive control forces. Primary Flight Controls Aircraft control systems are carefully designed to provide adequate responsiveness…

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 ... 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…
