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. The term is somewhat loosely applied, and can also refer to other … See more Extra power, or specific excess power, is a very basic method of determining an aircraft's flight envelope. It is easily calculated, but as a downside does not tell very much about the actual performance of the aircraft at … See more A doghouse plot generally shows the relation between speed at level flight and altitude, although other variables are also possible. It takes more effort to make than an extra power calculation, but in turn provides much more information such as ideal flight altitude. … See more This phrase is used to refer to an aircraft being taken to or beyond its designated altitude and speed limits. By extension, this phrase may be used to mean testing other limits, either … See more A chart of velocity versus load factor (or V-n diagram) is another way of showing limits of aircraft performance. It shows how much load factor … See more Although it is easy to compare aircraft on simple numbers such as maximum speed or service ceiling, an examination of the flight envelope will reveal far more information. … See more • Coffin corner (aviation) • Helicopter height–velocity diagram • Küssner effect • Maneuvring speed • Corner case See more WebJan 23, 2014 · When we were flight instructing, the explanation usually involved lots of white-board diagrams - with lots of bad dry-erase art. So, to help rid the world of bad CFI art, we've released our first CFI tool - which interactively shows you how CG location affects performance. ... However, you need to keep the CG within your aircraft's envelope. If ...
