Abstract
Present novel and non-trivial systems and methods for altitude data from a radar system and employing such data to verify altitude data from another source. A processor receives reflection point data generated by an aircraft radar system and reference point data from an applicable data source. Based upon the reflection point data and reference point data, first altitude data representative of a first measurement of aircraft altitude is generated. Then, the processor receives second altitude data representative of a second measurement of aircraft altitude from another source. Validity of the second altitude data may be determined by comparing it with the first data, after which validity advisory data may be generated that, is responsive to the validity determination. Then, the processor may provide the validity advisory data to a presentation system, whereby validity information of the second altitude data is presented to the pilot.
