METHOD AND DEVICE FOR MEASURING ALTITUDE ON AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2021/057361
Kind Code:
A1
Abstract:
A method for measuring the altitude on an aircraft. Generally, an electronic device (100, 200) displays an altitude acquired according to a first detection manner. When a first switching condition is satisfied, the electronic device (100, 200) displays an altitude acquired according to a second detection manner. In this way, generally, the electronic device (100, 200) displays an altitude detected according to an air pressure sensor; when the air pressure value of an environment where the electronic device (100, 200) is located is inconsistent with an atmospheric pressure value, data of the air pressure sensor is invalid; and the electronic device (100, 200) displays an altitude acquired by means of another detection manner. According to the present invention, in the case where a user takes an aircraft, an electronic device (100, 200) can display an accurate altitude.
