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 ...
Previously, every airline had its own system, which made the sharing and aggregation of flight delay information difficult. IATA standardised the flight delay reporting format by using codes that attribute cause and responsibility for the delay; this supports aviation administration and logistics and helps to define any penalties arising.
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.
The first flight of an SR-71 took place on 22 December 1964, at USAF Plant 42 in Palmdale, California, piloted by Bob Gilliland. [113] [114] The SR-71 reached a top speed of Mach 3.4 during flight testing, [115] [116] with pilot Major Brian Shul reporting a speed in excess of Mach 3.5 on an operational sortie while evading a missile over Libya ...
FAA Practical Test. A practical test, more commonly known as a checkride, is the Federal Aviation Administration examination which one must undergo in the United States to receive an aircraft pilot's certification, or a rating for additional flight privileges. The name refers to the portion of the examination in which the candidate being ...
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.
In aerodynamics, the flight envelope, service envelope, or performance envelope of an aircraft or spacecraft refers to the capabilities of a design in terms of airspeed and load factor or atmospheric density, often simplified to altitude. [1][2] The term is somewhat loosely applied, and can also refer to other measurements such as maneuverability.
