APQ-153 Fire Control Radar Antenna, Receiver-Transmitter, and Control Test Set

This test set was built for an avionics repair/overhaul shop to repair and overhaul the antenna, receiver-transmitter, and control for the APQ-153 and APQ-159 Fire Control Radar on the F-5E aircraft. It is identical to the test set part number 633175-303 that was manufactured by Emerson Electric Corp. This test set complements the Indicator and Processor Test Set part number 633176-307 also manufactured by Emerson Electric Corp.

329B-8J Flight Director Indicator Test Set

This test set was designed to exercise all the pointers, displays, and flags simultaneously. The customer’s requirements were stated as such because the manufacturer’s (Collins) test set (980L-1) only tested each function individually. An electronic circuit was designed to produce a slow and varying voltage that is adjustable in the upper and lower limit. Each function has their own circuit. One circuit to move the runway symbol in altitude, one to move it back and forth simulating the localizer deviation, another circuit drives the glideslope pointer up and down, another drives the speed command pointer up and down, another drives the rate-of-turn pointer, another drives the yellow command bar (V-Bar) in pitch, another circuit drives it in roll, and another drops the speed, glideslope, and rate-of-turn flags on and off at intervals of several seconds. A motor drive module was designed and built to move control transformers simulating the pitch and roll inputs from the vertical gyro. The circuit boards were designed, made, built, and assembled with components. The front panel was designed to the customer’s requirement. The chassis box was assembled with the circuit boards, power supplies, and motor drive module. It was then wired to the 329B-8J indicator. It has a scorsby table mounted on top of it to meet customer’s requirements to simulate the aircraft pitch and roll rocking motion.

Thales Vertical Speed Indicator Test Set

This test set was designed and manufactured to operate the Thales Vertical Speed Indicators part number series 457400. This test set has ARINC 565 vertical speed outputs: 26Vac REF and phase selected Vertical Speed output to indicator, ARINC 575 DC vertical speed outputs: + / – 12vdc REF and polarity selected DC output, lighting output voltage, remote light sensor outputs, and  ARINC 429 inputs/outputs. The first photo shows the test set in operation with the indicator showing intruder targets in the ARINC 429 High Speed TCAS test.

Collins 514M-2 Interface Test Panel

This test set was built per Rockwell Collins drawings. This test panel is an interface between the 972V-1 Test Set and the 374D-3 Collins ARN-139 TACAN Receiver-Transmitter part number 622-5146-001 used on the KC-10 aircraft. Printed circuit board and the front panel were designed and manufactured per the Component Maintenance Manual. Components installed in circuit board. Circuit board then installed in panel and chassis assembly with associated hardware and other electronic components. Cables manufactured to interface to the 374D-3.  The first photo shows the completed test set, the second shows the rear of the test set with circuit board, and the third shows it in operation with the 972V-1 and a 374D-3 Receiver-Transmitter under test.
