China Airlines Flight 006 damaged by going outside its flight envelope to gain control after a drop of 3,000 m in 20 seconds. Flight envelope protection is a human machine interface extension of an aircraft's control system that prevents the pilot of an aircraft from making control commands that would force the aircraft to exceed its structural and aerodynamic operating limits.
The Airbus A320 family was the first airliner to feature a full glass cockpit and digital fly-by-wire flight control system. The only analogue instruments were the radio magnetic indicator, brake pressure indicator, standby altimeter and artificial horizon, the latter two being replaced by a digital integrated standby instrument system in later production models.
Anti-stall (aeroplane controls), a flight envelope protection system designed to prevent an aircraft for stalling, for example by pushing the nose down; Anti-stall strakes, leading-edge slots or extensions, and stall strips; in fluid and aerodynamics, extensions that generates a vortex on a wing surface to postpone aerodynamic stall
The E2 features a closed loop fly-by-wire flight control system which reduces weight, increases fuel efficiency, enhances control and increases safety by full envelope protection in all flight phases compared to the first E-Jet. [52]
By September 2017, the prototype had flown 10,000 mi (16,093 km) in a series of flights of at least 30 mi (48 km) each. The first pre-production aircraft was flown in October 2017. [1] [5] The design is intended for the FAR 103 Ultralight Vehicles category in the United States and the Basic Ultralight Aeroplane category in Canada. The American ...
The fly-by-wire electronic flight control system of the Boeing 777 differs from the Airbus EFCS. The design principle is to provide a system that responds similarly to a mechanically controlled system. [10] Because the system is controlled electronically, the flight control system can provide flight envelope protection.
Avidyne was first to certify big glass for light GA with the 2003 launch of Entegra in Cirrus aircraft. This is considered a "first generation" big-glass system that integrates the six 3-inch instruments (6-pack) into a more usable package, along with an exceptionally reliable Air Data and Heading Reference System (ADAHRS) that replaces the "spinning mass" attitude and directional gyros.
Flight envelope is one of a number of related terms that are used in a similar fashion. It is perhaps the most common term because it is the oldest, first being used in the early days of test flight. It is closely related to more modern terms known as extra power and a doghouse plot which are different ways of describing the flight envelope of ...
