REQUIREMENT DESCRIPTION WITH SALIENT CHARACTERISTICS

In detail, please describe those physical, functional, performance, or material element qualities of an item that are essential to ensure that the intended use of the item can be satisfactorily realized.

ILS Glideslope

ILS (Instrument Landing System) cable assemblies, installation kits, and antenna arrays are critical items necessary for Andersen Air Force Base's continued operation of its two runways. This equipment will allow continued operations in inclement weather, providing Instrument Flight Rules arrivals and departures. All glideslope sites must have maintainer adjustable output levels to interface with existing ATC (Air Traffic Control) equipment. All standards established herein are required for two independent Glideslope sites. The end goal is to have the MAWAR destroyed tower, rebuilt to sustain continued and safe operations of Andersen's main primary runway. This glideslope site will need to be re-established, this requires 7 total component orders, with some that include itemized parts within.

Required Specs:

Frequency Range 328 MHz to 336 MHz UHF +/- 0.002% Type of Radiation - Horizontally polarized, amplitude-modulated radiation front to back ratio of 16dB Horizontal Coverage and Vertical Coverage covered in Figure 5-21 and Figure 5-22 of

31R4-2GRN31-2

Power Requirements 120VAC 50/60-Hz

The RMC (Regional Maintenance Center) and local RAWS work centers routinely maintain a standard set of ILS Glideslopes. These ILS Parts are ordered on a as-needed basis, from Non-DOD contractors due to their use for commercial applications, and lack of sufficient inventory in the Air Force supply system for complete rebuilds.
