How many comsets can reside on the A/C at any given moment?

• A. 8 comsets
• B. 10 comsets
• C. 12 comsets
• D. 15 comsets

Answer: (B)

The number is limited by the aircraft’s radio equipment rack and certification. The standard installation is configured to hold ten comsets, so at most ten transceiver modules can be present on the aircraft at any moment. This reflects how the system is designed to provide enough channels, redundancy, and spare capacity without overloading the hardware. Even though you might only actively use a subset at once, the physical slots available determine how many comsets can reside aboard. Choices smaller than ten would underutilize the rack, while larger numbers like twelve or fifteen would require a bigger, differently certified installation.
