Is there a requirement to inform the Radar Controller about KJAN or KMLU departures?

There is no requirement to inform the Radar Controller about KJAN or KMLU departures because these airports generally fall under procedures that do not necessitate such notifications unless specific circumstances arise. The communication protocols between pilots and radar controllers are designed to ensure effective management of air traffic, and typically, departures from certain airports may not require direct communication unless flight safety or specific operational needs dictate otherwise. This streamlined approach helps maintain efficient operations and allows pilots to focus on their flight management without overloading the radar controllers with unnecessary reports.

Other options suggest varying levels of communication error that could hinder operational efficiency in standard traffic conditions where no alerts or notifications are required.
