Systems and methods for selectively altering a ground proximity message

Abstract

Systems and methods for selectively altering a ground proximity warning message. In an embodiment, a ground proximity warning system for a flight vehicle includes a processor that is configured to generate a look-ahead envelope that defines a region extending outwardly from the flight vehicle and to generate a terrain proximity message when the defined region intersects a terrain feature. An interface device is coupled to the processor that is operable to configure the system in a first operating mode wherein the generated terrain proximity message is selectively suppressed, and a second operating mode wherein the terrain proximity message is not suppressed.

Description

BACKGROUND OF THE INVENTION[0001]Terrain Awareness and Warning Systems (TAWS) for aircraft such as fixed wing and rotary wing vehicles have significantly contributed to the safety of flight. Briefly, and in general terms, the TAWS is operable to acquire selected flight-related information from various aircraft systems and to obtain terrain information for topological features surrounding the aircraft. The TAWS is configured to process the flight-related information and the terrain information to determine if a potential safety condition due to terrain proximity is present. If a terrain proximity hazard is determined to exist, the TAWS provides a flight crew with a suitable audible and / or visual warning that timely alerts the flight crew regarding the detected terrain hazard.[0002]Although TAWS are generally effective in enhancing the safety of flight, drawbacks nevertheless exist. For example, in certain geographical locations, the aircraft may be intentionally operated relatively c...

AI Technical Summary

Benefits of technology

The present invention is about a system and method for changing a ground proximity warning message for a flight vehicle. The system generates a look-ahead envelope that defines a region around the vehicle and a terrain proximity message when the envelope intersects a terrain feature. The system can be configured to either suppress or not suppress the terrain proximity message based on the pilot's needs. The technical effect of this invention is to provide a more flexible and customizable ground proximity warning system for flight vehicles.

Problems solved by technology

Although TAWS are generally effective in enhancing the safety of flight, drawbacks nevertheless exist.

Accordingly, the numerous terrain proximity messages may constitute a nuisance that may distract the flight crew from other important flight-related tasks.
