All right, so now we're going to go ahead and run through our shut down procedure. We just got it back down on the ground. Our RPMs are still about 100 percent. Before we pull out our checklist or anything like that, we want to go ahead and roll our RPMs all the way down. You're just going to override the governor and just manually roll them down to 75.

Now at that point, the governor is no longer active, so it's not going to roll them up. We want to get that governor off, just so if we forget to pay attention to the RPMs, that governor doesn't roll on those RPMs when we don't want it to. Our RPMs are at 75 percent. Our governor's on.

We want to get our frictions back on, make sure that those aren't going anywhere, so our second friction is on. Come back to our collective friction and that's on and then we can go ahead and just put one foot on the pedal and make sure that our cyclic center is there, that way we free up one hand to do everything else. All right, so everything, all the frictions are on, cylinder head temperature dropped. What we're looking there is that our temperature has come down below 300 degrees. You can see there already we're at 300 degrees, because we didn't do a long flight. Now that we've confirmed our cylinder head temperature has dropped, we go ahead and close the throttle.

I just like to go ahead and put my hand all around the throttle again and just roll that throttle all the way to idle. Now we've confirmed it's all the way to idle. Once we do that, we'll get a clutch switch to start disengaging, so that way the belts start losing some of that tension, so we'll let that disengage for 30 seconds now, so I'll look at the clock and wait until we hit about 30 seconds. Just let that clutch get that time to disengage. Now we've got our clutch disengaged, we waited 30 seconds. Once we hit 30 seconds, we'll go ahead and pull our mixture guard off of our mixture and push down the button and just pull up our mixture all the way until you hear the engine shut off.

Once you get that off, you want to go ahead and grab our alternator and our [inaudible 00:02:01] to confirm that those are off.

Now we're going to go ahead and leave our master on, that way our strobe's still running because our blades are still turning. We want people to still see that the helicopter is still running. Go ahead and make sure to get our, leave our radio on so we can hear but we'll go ahead and get our transponder off. Then at this point, if you have a rotor brake, you're going to wait another 30 seconds and then you're going to start gradually pulling that rotor brake to slow down. We don't have a rotor brake, so we're just going to let those blades slow down and we're just going to wait in the helicopter until they quit spinning.
