- Definition
- A component of an Instrument Landing System (ILS) consisting of an Ultra High Frequency (UHF) transmitter radiating signals and providing a straight-line descent path in the vertical plane containing the centre line of the runway served by the ILS, and thereby furnishing descent information down to the surface of the runway.
- Description
- The descent information is that locus of points in the vertical plane containing the runway centre line at which the receiver indicator deflection is zero.
