Installation Checkout Using
an Alternate Display
E.1 INTRODUCTION
This section contains installation checkout procedures for the SKY497 that is interfaced to an alternate
display (e.g., BFGoodrich Avionics Systems RGC250).
NOTES
1. This section provides checkout information for the BFGoodrich Avionics
Systems SKY497 interfaced to an Alternate Display. When interfacing to an
alternate display the TRC497 must have software version 1.4 or above.
2. This procedure assumes familiarity with the set up and operation of the TT391
Flightline Tester and RS-232 terminal device (see Appendix D). If using
another approved tester refer to the appropriate appendices for test procedure.
3. All test equipment used in completing these tests shall be calibrated in
accordance with the manufacturer's recommendations.
This procedure will validate the installation and return to service of the BFGoodrich Avionics Systems
SKY497.
E.2 CONTROLS
Operating instructions for each alternate display are provided with the display manufacturers
documentation.
NOTE
When using an alternate display all SKY497 functions are controlled through
the alternate display. Each alternate display will show information consistent
with the capabilities of that particular display. Therefore, the text displayed
may be different from what is called out in this procedure. Reference the
alternate display documentation for appropriate screen text.
E.3 CHECKOUT PROCEDURE
The TT391 Flightline Tester simulates both a ground based secondary surveillance radar (SSR) and an
airborne transponder. With the SKY497 set to GROUND TEST (i.e., the barometric altimeter is simulated
to 50,000 ft, heading simulated to 0 degrees, and the radar altimeter simulated to 2,500 ft) the TT391 will
simulate two targets; a Traffic Advisory (i.e., a solid circle) at ΒΌ nm and Other Traffic (i.e., open diamond)
at 4.5 nm. Both targets will be displayed in level flight at own aircraft altitude (i.e., "00" displayed above
the traffic symbol).
If the indications given in the following procedure, except for the Flightline Tester, are not obtained, refer
to the troubleshooting procedures in Chapter 4. If indications given for the Flightline Tester are not
obtained, refer to the maintenance section of the TT391 Instruction Manual.
1. Connect the RS-232 terminal device to J7 TEST port on the TRC497. Setup and turn on the terminal
device. (See Appendix D for terminal device commands, setup, and operating instructions.)
2. Make sure the aircraft's transponder is in the STBY mode and the DME is turned OFF. At the
aircraft's instruments, verify all compass/HSI flags are valid.
