Which system gates signals to avoid interference between avionics?

• A. The MX-9965/A Interface Blanker System
• B. The RT-1022/ARN-99
• C. The AS-3422/ARN-99
• D. The TACAN Display Console

Answer: (A)

Gating signals to avoid interference between avionics means selectively blocking or allowing signal paths so one system’s activity doesn’t disrupt another. The MX-9965/A Interface Blanker System is built for this purpose: it blanks or gates signal interfaces between avionics, preventing cross-talk and EMI when systems switch or transmit. This keeps radar, navigation, and communications hardware from interfering with each other. The other items are general radios or displays, not dedicated to gating interfaces to prevent cross-system interference, so they don’t provide the same protection as an interface blanker.
