SECTION 3 FDL-978 SERIES CONFIGURATION AND CHECKOUT
3.1

General

This section contains installation configuration, checkout, and basic operating procedures.
Detailed operating procedures are contained in the Pilot Guide/User Manual.

3.1.1 Continued Airworthiness Requirements

The FDL-978 Series and FDL-978 Lite Series systems require no periodic maintenance or
calibration. Maintenance is performed on an on-condition basis only. These units perform a
power-on self-test (POST) and is continually tested using a Periodic Built-In Test (PBIT) when
the system is in operation. This method of testing will notify the operator of a failure. System
software updates are accomplished using the MPI.
Continued airworthiness can also be accomplished by determining the FDL-978 Series and
FDL-978 Lite Series installed system performance using the FFS FT-9000 Ramp Tester (see
Section 1.7.2 for more information).

3.1.2 TC978 Controller Operation

The FDL-978 Lite Series and FDL-978-XVR can interface to a TC978 Controller used in-flight by
the pilot to control output of ADS-B messages. The TC978 receives its power from these units
and communicates to them through an RS-485 serial port. The TC978 Controller receives its
power from and communicates with the FDL-978-XVR Transceiver. The TC978 Controller
consists of the following components:
 Monochrome Liquid Crystal Display (LCD)
VFR button

FN button (Function)

CODE knob

ENT button (Enter)

Mode Selection knob

IDT button (Ident)

For instructions on using the TC978, refer to the FDL-978 ADS-B Equipment Pilot Guide/User
Manual, document number 87351.
