sleeve after drilling can be removed using a pointed tool and applying an adhesive solvent to the sealant. Control Cables & Terminals Cables are the most widely used linkage in primary flight control systems. Cable-type linkage is also used ... cable has a high mechanical efficiency and can be set up without backlash, which is very important for precise control. Cable linkage also has some disadvantages. Tension must be adjusted frequently due to stretching and temperature changes. Aircraft control cables…

manufacturer to measure control surface travel. Markings on the fixture or template indicate desired control surface travel. Figure 2-75. Tensiometer. Tension Regulators Cable tension regulators are used in some ... flight control systems because there is considerable difference in temperature expansion of the aluminum aircraft structure and the steel control cables. Some large aircraft incorporate tension regulators in the control cable systems to maintain a given cable tension automatically…

boost systems assist the pilot in overcoming high control forces, but the pilot still actuates the flight controls by cable or push rod. Many modern aircraft use a power supply system and fly-by wire flight control. The pilot input is electronically sent to the flight control servos. Cables or push rods are not used. Small power packs are the latest evolution of the hydraulic system. They reduce weight by eliminating hydraulic lines and large…

autopilot servos must allow unimpeded control surface movement when the autopilot is not operating. Aircraft with cable actuated control surfaces use two basic types of electric motor-operated servos. In one, a motor is connected to the servo ... shaft in the opposite direction. [Figure 10-109] Electro-pneumatic servos can also be used to drive cable flight controls in some autopilot systems. They are controlled by electrical signals from the autopilot amplifier and actuated…
