Airplane Status System

A flight deck display that represents the overall health of the airplane by combining energy state, system state and configuration state into one integrated representation that is triggered by the on-board engine indication and crew alerting system. The computer system for controlling the display unit is configured to display an airplane status indicator in the form of a symbolic representation of the airplane that persists across displays. The status indicator shows the energy state of the airplane and how energy is being added or subtracted from it in terms of altitude, airspeed, thrust, wind, etc. As the airplane gains energy, there is a projection of excess energy shown in front of the airplane. As the airplane loses energy, an alerting indicator will appear around the airplane symbol if the performance of the airplane becomes is too low.
