Which systems are selected by the EEC?

• A. A/P (Electronic Flight System), IFF, TCN (TACAN System), ILS, Data Link (D/L), BCN (RADAR beacon subsystem), COMM (UHF/VHF volume, channel display, and channel selector controls), ADF (Automatic direction finding subsystem)
• B. A/P only
• C. ILS and D/L
• D. IFF and ADF

Answer: (A)

The EEC acts as the central selector and integrator for the aircraft’s avionics, determining which major systems are available and actively coordinated for flight operations. The best choice lists the full spread of subsystems the EEC must manage: Autopilot (flight control), IFF (identification Friend or Foe), TACAN (navigation), Instrument Landing System (landing guidance), Data Link (data exchange), radar beacon subsystem, communications, and Automatic Direction Finding. Together, these represent the broad set of functions the crew relies on and the EEC must prepare for, from automated flight control and precise navigation to airspace identification, beacon/radar cues, and robust comms and data capabilities. Narrow options that pick only one or a small subset don’t reflect the integrated role of the EEC in handling the full avionics suite.
