TRACALS Evaluation Report. Solid State Instrument Landing System, AN/GRN-29(V). Special Evaluation Report, Tinker AFB, Oklahoma, 8-12 December 1980.
Abstract
The 1866th Facility Checking Squadron was tasked to perform a special evaluation of the Solid State Instrument Landing System (SSILS) at Tinker AFB, Oklahoma, and produce an amendment to the TRACALS Evaluation Report 80/66S-244. Authority for this action was HQ AFCC/FFNM (now ATTE) letter dated 27 September 1982 referencing CCD/LGM message 232110Z September 1982. The purpose of the evaluation was to update the last TRACALS Evaluation Report after a frequency change of the SSILS and to look at a localizer scalloping problem. The results of the ground equipment checks indicated the localizer was operating within technical order (TO) specifications. The phasing of the course and clearance systems of both transmitters was optimized prior to the flight evaluation. Analysis of the localizer facility siting reconfirmed that line fo sight coverage of the runway threshold was limited. The hump in the ground elevation immediately in front of the antenna array reduces the signal strength in the area of the restriction.
