FR NO COM describes which failure scenario?

• A. FR NO COM
• B. NOT ARMD
• C. VALVFAIL
• D. CALCE FAILURE

Answer: (A)

FR NO COM describes a scenario where radio communications are lost. The phrase NO COM explicitly denotes no communication, so this failure right away points to a loss of radio contact with ATC or other required channels. The other options refer to different failure types (not armed, a valve failure, calibration-related issue), which do not describe a loss of communications. In this kind of situation, the appropriate response is to follow lost-communications procedures (squawk 7600, continue the last assigned route/altitude, and proceed as cleared or as filed).
