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 ...
One example of such a flight envelope protection device is an anti-stall system which is designed to prevent an aircraft from stalling, [7] for example in the form of a stick pusher that pushes the aircraft nose downward based on an input signal from a stall warning system, [8] or by means of other fly-by-wire actions.
Flight at the absolute ceiling is also not economically advantageous due to the low indicated airspeed which can be sustained: although the true airspeed at an altitude is typically greater than indicated airspeed (IAS), the difference is not enough to compensate for the fact that IAS at which minimum drag is achieved is usually low, so a ...
Normal flight parameters are defined as: Pitch attitude between 25° nose-up and 10° nose-down. Bank angle less than 45°. Airspeed versus maneuver loading within the normal flight envelope. This expanded definition is intended to more fully capture the maneuvers, events, conditions, and circumstances that the record has shown lead to LOC. [11]

In aerophilately, a branch of philately, a first flight cover, also known by the acronym FFC, is mail that has been carried on an inaugural flight of an airline, route, or aircraft, [1] normally postmarked with the date of the flight [2] often of the arrival destination proving it was actually carried on the aircraft [3] and may have a special ...
