With rotor brake applied, which interlock allows you to move the PCLs from idle to fly?

Explanation:
With the rotor brake applied, the system uses an idle interlock to require a deliberate action before moving from idle toward flight. The idle interlock lever overrides the normal PCL interlock when the rotor brake is engaged, allowing you to move the Power Control Levers from idle to the flight range. This keeps you from inadvertently advancing the PCLs and potentially causing an unintended rotor response while the rotor is held by the brake. The gust lock simply locks the rotor when parked, and the PCL interlock switch or throttle lock don’t provide this specific override needed to go from idle to fly with the rotor brake on.
