HDG and OBS Track Select Panel
TA-260
-
Universal Heading and Track Selector Panel This panel provides a synchro transmitter for Heading and a synchro resolver for Nav converter alignment. The synchros are mounted on industry standard 18:1 dual speed drives for maximum accuracy and repeatability. This unit can be used to calibrate both manual and automatic converters. This panel provides a rear mounted interface connector as well as front mounted tip jacks for independent breakout if so desired. The TA-260 also provides two discrete switches associated with the resolver configuration. The 30Hz/400Hz switch is provided to allow the resolver to be properly compensated for the type of Nav converter to be aligned. The second switch allows you to open or short the resolver rotor lead as may be required by some newer GPS equipment. This panel is lightweight enough for portable use or may be rack mounted.

AC Fuel Flow Signal Generator
TA-100
-
The TA-100 signal generator was designed to facilitate testing of aircraft fuel flow indicators that require two input signals designated as “Drum” and “Impeller”. This generator provides both signals so as to provide a direct interface to the fuel flow indicator under test. The generator also provides switched power out to the unit under test as well as a 5v source for testing the bezel lighting. The original design was built around the requirements for the AMETEK series indicators (pn: 10171 series). This generator simulates a reference and a time delayed signal of appropriate amplitude for an indication of up to 1200pph for the indicator under test. The “PPH Select” switch provides fixed signal delays representing 0, 200, 400, 800, 1000 and 1200pph flow rates respectively, this provides the mechanic with an expedient check of the indicators accuracy. The “PPH Adjust” control allows the mechanic to vary the signal delay throughout the full range and serves as a good method for checking of pointer smoothness from stop to stop. The unit’s front panel also provides test jacks to monitor the “FDR Output” as well as the drum and impeller signals. The TA-100 requires only 28Vdc to operate. This generator provides a very economical approach to any repair facility or flight department as it becomes an alternative to purchasing two bench top signal generators. The TA-100 generator at the very least can provide a simple functional test and eliminate the high cost of exchanging an indicator as a function of troubleshooting the aircraft system.

Serial Distance Display
TA903-03
-
This panel mounted or portable display will read Bendix/King serial distance as generated by their DME systems or GPS products. This long standing three wire format of CLK, DATA and REQ can now easily be displayed without the expense of a KTS143 test fixture. This product is ideal for shop and aircraft troubleshooting. The extruded aluminum enclosure is a standard DIN size(1/8) and the unit interfaces through a 25 pin D connector.

ARINC HSI / ADI Test Fixture
TA-2000
-
The TA-2000 test fixture is a combination panel that incorporates all the standard capabilities of the legacy CTS-11(ADI) and CTS-12(HSI) panels and much more. This panel is married to our model TA-1001 dual synchro transmitter/API panel thus allowing for local stimulus and alignment of the instruments synchros and resolvers. The panel provides for testing of both superflag(28v) and low level meters through a matrix of switching that will allow testing of all meters simultaneously or just individually. The low level meter drive circuit also incorporates an automatic mode that will continuously oscillate the L/R and Up/Dn pointers.

ADI Test Fixture
TA-6500
-
The TA-6500 test fixture combines the features of the OEM's Instrument Servo Tester(T307962), the Pointer/Flag Test Fixture(T307951) and the AD-650/600 Test Panel(T334043) all into one panel to facilitate testing of these Attitude Director Indicator's. The panel switches and adjustment pots are labeled to match the test procedure numbers and the duplicity in marking makes it easier for the technician to understand each function. The UUT interface is through a 96 pin zero insertion force(ZIF) type connector to minimize contact wear. The expanded localizer and nav input pins J2-34/35 are exposed on the panel to facilitate the insertion of a 200 ohm shunt when required. The fixtures rear panel has connectors for the required dual API/Synchro transmitter interface while the panel switches provide the correct routing of each.
