Turbine-powered aircraft operate at high altitudes where temperatures can be extremely low. Under these conditions, water present in the aircraft fuel can freeze and form ice crystals. These ice crystals may restrict fuel flow, particularly when they accumulate on fuel filter elements. Fuel heaters are therefore used in turbine-powered aircraft to prevent ice formation and … Read more
Aircraft nose wheel steering systems provide directional control during ground operations such as taxiing, takeoff, and landing. This article explains mechanical and hydraulic nose wheel steering systems, steering damping, and the different types of shimmy dampers used to control unwanted nose wheel oscillations. The nose wheel on most aircraft is steerable from the flight deck … Read more
The moving parts and dirty environment of the landing gear make this an area of regular maintenance. Because of the stresses and pressures acting on the landing gear, inspection, servicing, and other maintenance are continuous requirements. The most important aspect of aircraft landing gear system maintenance is conducting thorough and accurate inspections. To properly perform … Read more
Aircraft landing gear must be properly aligned, securely supported, and reliably retracted and extended to ensure safe ground operations and flight. This article explains landing gear alignment, structural support, retraction systems, emergency extension systems, safety devices, position indicators, and nose wheel centering. Retractable landing gear consist of several components that enable it to function. Typically, … Read more
Aircraft landing gear supports the entire weight of an aircraft during landing and ground operations. They are attached to primary structural members of the aircraft. The type of gear depends on the aircraft design and its intended use. Most landing gear have wheels to facilitate operation to and from hard surfaces, such as airport runways. … Read more
Smaller aircraft have relatively low flight control surface loads, allowing the pilot to operate the flight controls directly by hand. Early hydraulic systems were first used only for aircraft brake systems. As aircraft became larger and faster, however, the aerodynamic loads on the control surfaces increased to the point where manual operation was no longer … Read more
Aircraft fire protection systems are designed to detect, warn, and extinguish fires before they can threaten the safety of the aircraft and its occupants. Because aircraft contain fuel, electrical systems, hydraulic fluids, and high-temperature components, the risk of fire is always present. Fire protection equipment must therefore operate quickly and reliably in both normal and … Read more
Wood was one of the earliest materials used in aircraft construction. During the pioneering years of aviation, aircraft structures were commonly built using wood frameworks covered with fabric. Wood offered several advantages, including light weight, good strength-to-weight ratio, and the ability to be shaped into structural components using relatively simple tools and techniques. Early aircraft … Read more
Without modern metalworking tools and machines, the job of the airframe technician would be more difficult and tiresome, and the time required to finish a task would be much greater. These specialized tools and machines help the airframe technician construct or repair sheet metal in a faster, simpler, and better manner than possible in the … Read more
Fabric covering has been a critical component of aircraft construction since the earliest days of aviation. It provides a lightweight, durable skin that protects the internal structure, maintains aerodynamic shape, and contributes to overall structural integrity. Understanding the history and development of fabric covering is essential for anyone involved in aircraft maintenance or restoration. This … Read more
