Flight Envelope


In aerodynamics, the flight envelope defines operational limits for an aerial platform with respect to maximum speed and load factor given a particular atmospheric density. The flight envelope is the region within which an aircraft can operate safely.

1.   The navigation function forms part of the Guidance, Navigation and Control (GNC) system and consists of calculating a platform's location and velocity (also known as the state vector), as well as its orientation (or attitude). Navigation relies on input from a variety of sensors and subsystems.

In the very early stages of aviation, control of an aircraft was based purely on visual feedback and sensorial perception: flying ‘by the seat of the pants’. Such instruments as were available in the cockpit were very basic and limited in their capacity. As aircraft complexity has increased, more information and more complex instruments have become available.
