Flying

Shutdown

From the ground run back to a cold aircraft.

PLT

Land, collective fully down, and hold the aircraft still.
Weapons: de-action everything and set the armament panel to SAFE.
NVS mode: OFF.
Power levers: IDLE. Let the engines run at idle for a minute or two so TGT comes down. A hot engine restarted too soon starts hot.
Power levers: OFF. Ng and Nr run down.
Rotor brake: BRK once Nr is below 50%. The brake does nothing above that. It stops the rotor in well under a minute; set LOCK to hold it.
APU: off, if it is running.
MSTR IGN: OFF. The displays go dark.
HDU: stow the monocle.

The ROTOR BRAKE ON advisory with both levers off is normal. The RTR BRK ON/LK caution means a power lever is off its OFF stop with the brake set.
