Aircraft boundary transition warnings and auto alerting
First Claim
1. A method of providing information indicating the relative proximity of an aircraft to restricted airspace, comprising the steps of:
- determining position of the aircraft, determining boundaries of restricted airspace local to the aircraft position, generating at least one aircraft alert zone representing a region surrounding the aircraft, determining whether the aircraft alert zone intersects boundaries of the restricted airspace, and indicating whether an aircraft alert zone has intersected boundaries of the restricted airspace.

Abstract
In combination with a Geographic Information System (GIS), 3-dimensional shapes may be used to designate or identify blocks of airspace. These shapes may be defined in many ways including lat/long, local coordinates, or FAA transmitted directions for TFRs and ADIZs. These restricted areas and zones may be modeled using suitably modified AirScene™ software from Rannoch Corporation. AirScene™ software can locate various aircraft in the vicinity of restricted airspace, determine whether the aircraft is about to enter restricted airspace, and issue a warning to the pilot of such aircraft that restricted airspace is about to be violated. Such a warning can be audible (e.g., radio communication message) or visual (e.g., graphic display or even a flashing light or text message) and is much less distracting than having a laser shining in the cockpit. Since the AirScene™ system is ground-based, ground personnel can also be advised if restricted airspace is being violated, or even about to be violated.
