• A. False
• B. Not Applicable
• C. Unknown
• D. True

Answer: (D)

The main concept here is how ATC handoffs and frequency changes work. When ATC tells you to switch to another frequency or contact a different controller on a new frequency, that directive itself serves as your authorization to switch. You should tune to the new frequency and establish communication immediately, rather than waiting for a separate clearance. This ensures continuous contact and smooth transitions during procedures like handoffs and during busy phases of flight.

So, switching is done in response to ATC instruction, and no additional clearance is needed beyond that instruction. If you waited for a separate clearance before switching, you could risk losing contact or creating a delay during critical phases.
