instrument landing system (ILS)Landing aid for aircraft that uses radio beacons on the ground and instruments on the flight deck. One beacon (localizer) sends out a vertical radio beam along the centre line of the runway. Another beacon (glide slope) transmits a beam in the plane at right angles to the localizer beam at the ideal approach-path angle. The pilot can tell from the instruments how to manoeuvre to attain the correct approach path. How to thank TFD for its existence?

Upon intercepting the red/amber interface on the stabilized glide slope indicator (SGSI) at .

The project included construction of a new 75-foot-wide concrete taxiway with asphalt shoulder, taxiway edge and centerline lighting, lighting vault modifications, and the relocation of a Federal Aviation Administration's glide slope facility and a security airfield vehicle checkpoint. |
