Abstract
A method and system for detecting errors in indicated air speed of an aircraft. The method may include receiving current measured data values indicative of one or more of a pressure altitude, vertical speed, pitch attitude, and engine power of the aircraft by a computer, accessing a table having values of indicated air speed (IAS) corresponding to the current measured data values, and computing from the table and the current measured data values a current expected IAS, receiving current data values indicative of measured IAS of the aircraft, comparing the expected IAS data values to the measured IAS data values, and generating an alert signal when the expected IAS data values and measured IAS data values differ by a pre-set amount. The computer may include a software module that utilizes output from pre-existing on-board sensors, and may generate a signal to a crew alerting system.
