This intersection is the coffin corner, or more formally the Q corner. [3] The above explanation is based on level, constant speed, flight with a given gross weight and load factor of 1.0 G. The specific altitudes and speeds of the coffin corner will differ depending on weight, and the load factor increases caused by banking and pitching maneuvers.
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 ...
A flight envelope diagram showing V S (Stall speed at 1G), V C (Corner/Maneuvering speed) and V D (Dive speed) Vg diagram. Note the 1g stall speed, and the Maneuvering Speed (Corner Speed) for both positive and negative g. The maximum “never-exceed” placard dive speeds are determined for smooth air only.
A sample CG-moment envelope chart, showing that a loaded plane weighing 2,367 lb (1,074 kg) with a moment of 105,200 lb⋅in (11886 N⋅m) is within the "normal category" envelope. Center of gravity (CG) is calculated as follows: Determine weights and arms for all mass within the aircraft. Multiply weights by arms for all mass to calculate moments.
Because the federal government has funded the development of FalconView, it is a nonproprietary "government off-the-shelf" (GOTS) application and is free of any license fees for government use. This includes the use of the Software Developers Kit (SDK) which documents the interfaces for use by government developers and contractors working on ...

The term "corner case" comes about by physical analogy with "edge case" as an extension of the "flight envelope" metaphor to a set of testing conditions whose boundaries are determined by the 2 n combinations of extreme (minimum and maximum) values for the number n of variables being tested, i.e., the total parameter space for those
