The A/C's storage for comsets at once is what maximum count?

• A. 2 comsets
• B. 10 comsets
• C. 9 comsets
• D. 11 comsets

Answer: (B)

The main idea is how many preset communication configurations (comsets) an aircraft's radio can store at one time. A comset is a saved set of parameters—typically the receive/transmit frequencies and related settings for a particular channel—that lets you switch to that channel instantly without manually entering frequencies.

Ten comsets is the design limit for this radio system, so you can preload a bank of frequently used frequencies (for example, several ATC channels, a company channel, and a backup). This fixed memory capacity keeps the cockpit workflow efficient while avoiding the need to type in frequencies repeatedly. Other numbers aren’t the stated maximum for this setup, which is why ten is the best choice.
