Abstract
An automatic landing system (ALS) includes an automatic landing module. The automatic landing module receives a radio altitude from a radio altimeter and any other sensor inputs for use by the automatic landing module and generates an ALS elevator command. The ALS also includes a runway slope compensation (RSC) module. The runway slope compensation module receives the ALS elevator command, the radio altitude and an inertial vertical speed from an inertial reference unit and generates an aircraft elevator command and at least one symmetric wing surface command. The aircraft elevator command and the at least one symmetric wing surface command are useable by an aircraft for runway slope compensation.
