System and method for displaying runway approach information

摘要

A system and method are disclosed for indicating to an aircrew of an aircraft an unstable approach to a desired landing. When the energy state of the aircraft exceeds a threshold, a suggested airspeed in consideration of the energy state is displayed. Additionally, a landing spots on a displayed runway are shown indicating where the aircraft would land in view of the energy state and where the aircraft is recommended to land in view of the current aircraft type and weight. A text message may also be displayed that conveys the ability of the aircraft to land.

主权项

1. A system for assisting a pilot of an aircraft to fly a stable approach to a landing, the system comprising:
a processor configured to:
determine an aircraft energy state of the aircraft; andcompare the aircraft energy state of the aircraft with a desired stable approach energy state, a display configured to:
display a first symbol indicating a speed change rate required to obtain a stable approach based on the comparison;display a runway representation symbol;display a second symbol on the runway symbol indicating where the aircraft would touch down at the aircraft energy state determined by the processor;display a third symbol on the runway symbol indicating where the aircraft would touch down at the desired stable approach energy state,wherein the second symbol overlies the third symbol when the comparison is within a threshold.
