Abstract: A system and a method include a control unit configured to compare first QNH data received from a first QNH data source, second QNH data received from a second QNH data source that differs from the first QNH data source, and a QNH input entered into an avionics system of an aircraft. The control unit is further configured to output an alert signal in response to the QNH input differing from one or both of the first QNH data or the second QNH data.
