Abstract
The present invention is a method for obtaining a localizer deviation and a glide slope deviation for an aircraft. The method may include directing electromagnetic signals from a weather radar system of an aircraft towards a runway. The method may further include receiving return signals in response to the directed signals. The method may further include, based on the received return signals, determining an azimuth angle for the aircraft relative to the runway, determining an elevation angle for the aircraft relative to the runway, and determining a range for the aircraft relative to the runway. The method may further include based on the azimuth angle, the elevation angle, and the range, calculating the localizer deviation and the glide slope deviation for the aircraft.
