KMD540 Series and RDR2000/2100 Panel
TA-3C
-
The TA-3C test fixture is a combination of the KMD540 testing requirements and the RDR-2000/2100 weather radar interface requirements. This panel allows the technician to test the KMD540 MFD as a stand alone item (with external simulators) or together with a radar sensor for a dynamic real time test. The panel includes the required switching for sensor alignment and KMD testing along with input jacks for the required data inputs. Also built into the fixture is an analog gyro simulator for checking the stabilization functions of the sensor. The full enclosure comes in standard panel width.

Test Fixture with API
TA-14VG
-
The TA-14VG test fixture is based on the requirements for the Integrated Test Procedure for the VG-14A assembly as shown in the OEM maintenance manual. The panel also contains a test point breakout for the units main connector as well as one for the VG-401 base. The VG-401 breakouts provide an in series connection that will allow easy access to the gyro's signals and also provides a way to monitor rotor current. The panel also contains a variac to allow for line voltage adjustment.

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.

Customer Acceptance Test Panel
TA-65
-
DGS-65 Customer Acceptance Panel for both testing and trouble- shooting. We have added an option to the panel that allows you to select an analog slaving meter or the LED monitor lights as shown in the maintenance manual Fig. 5-14. The addition of the meter provides the technician with a more visible means to monitor the slaving "trend". The 50 pin DG connector is broken out on the panel to assist in monitoring or isolating unit signals.

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.

Mach Airspeed Test Fixture
TA-6055A
-
The TA-6055A is a Mach Airspeed Test Fixture built to support the testing and repair of the 2082 and 2083 series of Servoed Mach Airspeed Indicators (SMASI) used in some Boeing aircraft. These mach airspeeds are synchro driven and require a coarse and fine input for altitude and a third input for airspeed. This test fixture was designed around the test procedure and is interfaced with our TA-1001 panel which provides for two of the synchro sources and two Angle Position Indicators (API).
