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 ...
V A is the design maneuvering speed and is a calibrated airspeed.Maneuvering speed cannot be slower than and need not be greater than V c. [4]If is chosen by the manufacturer to be exactly the aircraft will stall in a nose-up pitching maneuver before the structure is subjected to its limiting aerodynamic load.
The software ran on MS-DOS, with a version for Windows 3.1 released not long after. [ 1 ] The initial versions of FalconView were simply a set of routines to display scanned raster maps such as CADRG (compressed arc digital raster graphics) with simple stick routes drawn on top, but the easy to use software was popular with the end users and ...
Another factor that makes it impossible for some aircraft to reach their absolute ceiling, even with temporary increases in thrust, is the aircraft reaching the "coffin corner". 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 ...

The low speed region of flight is known as the "back of the power curve" or "behind the power curve" [7] [8] (sometimes "back of the drag curve") where more thrust is required to sustain flight at lower speeds. It is an inefficient region of flight because a decrease in speed requires increased thrust and a resultant increase in fuel consumption.
