The C check is performed approximately every 20–24 months, or a specific number of actual flight hours (FH), or as defined by the manufacturer. This maintenance check is much more extensive than the B check, requiring a large majority of the aircraft's components to be inspected. This check puts the aircraft out of service for 1–4 weeks.
Operational loads monitoring (OLM) is a term given to act of investigating the characteristics of a structure in its normal operating environment. This term is often used to describe programs involving aircraft to extending their in-service life in a manner that does not compromise flight safety. [1] A typical program would involve the ...
These codes are used to describe technical delay reasons. 41 (TD): Aircraft defects. 42 (TM): Scheduled maintenance, late release. 43 (TN): Non-scheduled maintenance, special checks and / or additional works beyond normal maintenance. 44 (TS): Spares and maintenance equipment, lack of or breakdown.
Load factor (aeronautics) In aeronautics, the load factor is the ratio of the lift of an aircraft to its weight [1][2]: § 5.22 and represents a global measure of the stress ("load") to which the structure of the aircraft is subjected: where. is the weight. Since the load factor is the ratio of two forces, it is dimensionless.
DO-160, Environmental Conditions and Test Procedures for Airborne Equipment is a standard for the environmental testing of avionics hardware. It is published by the Radio Technical Commission for Aeronautics (RTCA) and supersedes DO-138.
Aircraft flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude. Development of an effective set of flight control surfaces was a critical advance in the development of aircraft. Early efforts at fixed-wing aircraft design succeeded in generating sufficient lift to get the aircraft ...
The control loading systems are designed to allow situating the actuators closer to the pilot. This is necessary for mission training systems [1] that can be easily deployed and moved around the world. Control Loading Systems are similar in design to active sidesticks. These provide cues to pilots during the flight via actuation systems.
ETOPS approval is a two-step process. First, the airframe and engine combination must satisfy the basic ETOPS requirements during its type certification. This is called "ETOPS type approval". Such tests may include shutting down an engine and flying the remaining engine during the complete diversion time.
