Systems and methods for updating a scale of a barometric altimeter on aircraft

摘要

Systems and methods for updating a scale of a barometric altimeter on aircraft are provided. The method, for example, may include, but is not limited to, receiving, by an aircraft communication system, barometric altimeter scale data corresponding to an atmospheric pressure at an airport, determining, by the processor, if the altitude of the aircraft is below a transition level for the airport, and adjusting, by the processor, the scale of the barometric altimeter based upon the received barometric altimeter scale data when the altitude of the aircraft is below the transition level for the airport.

主权项

1. A method for automatically adjusting a scale of a barometric altimeter on an aircraft having a processor communicatively coupled to the barometric altimeter, the method comprising:
receiving, by an aircraft communication system, a digital message including barometric altimeter scale data corresponding to an atmospheric pressure at an airport; determining, by the processor, when an altitude of the aircraft is below a transition level for the airport; comparing, by the processor, the received barometric altimeter scale data with a current scale setting of the barometric altimeter; indicating, on an aircraft display, the received barometric altimeter scale data when the received barometric altimeter scale data is different from the current scale setting of the barometric altimeter; and adjusting, by the processor, the scale of the barometric altimeter based upon the received barometric altimeter scale data when the altitude of the aircraft is below the transition level for the airport.
