First Claim
Patent Images
1. A method for alerting a flight crew of an aircraft when the aircraft is flying an approach to a taxiway, the method comprising:
- determining altitude of the aircraft;
determining whether the aircraft is within an envelope surrounding a predetermined runway based on a position of the aircraft, wherein the envelope has at least a first dimension associated with a first dimension of the runway and at least a second dimension with a second dimension of the runway; and
issuing an indication that the aircraft is approaching a taxiway if the aircraft is not within the runway envelope and the determined altitude is below a predefined threshold.

Abstract
A taxiway approach advisory system. The system may include a computer-readable memory containing runway information and a processor in data communication with the memory. The processor may include a component for ascertaining the altitude of an aircraft, a component for ascertaining the location of the aircraft, a component for accessing runway information from the memory and determining if the aircraft is within a pre-determined runway envelope based on the altitude and location, and a component for issuing an indication if the aircraft is not within the pre-determined runway envelope.
