Description
While the primary function of secondary surveillance radar (SSR) is to detect and identify aircraft, the radar response from the aircraft may also be encoded to indicate the aircraft altitude. This capability is known as Mode C and will indicate the aircraft pressure altitude at intervals of the closest 100ft.
