Thanks for sharing. I'm about to buy a B2. I love it's simple and cheaper. Thanks for your videos buddy

I’m so sorry I didn’t see your comment until now. Thank you so much for watching!

Bill Burr talks about it with so much passion, I had to check it out.

You really don’t want to run the engine at ground idle for 2 minutes like this guy did. The flight manual doesn’t recommend or specify a warm up time at ground idle, it says to go straight to flight idle after starting. The cool down time at ground idle is only 30 seconds when shutting down. Engine oil flow is poor at ground idle and you run the risk of coking up the front bearing oil feed in the turbine module if you run the engine at ground idle for longer than is necessary.

Oh that’s really interesting. Thank you for commenting.

Need time to do hyd checks.

i have Fleet of 8 choppers an i never knew Dat....LOL

Russell A is 100% correct on this. It’s refered to sometimes as the “critical bearing” and it sits aft of the gas producing turbine and forward of the free wheeling unit. It’s the hottest portion of the engine and where the T4 (turbine temperature) is measured. At ground flight idle, there is not enough cooling on that bearing because oil pressure is not sufficient to sustain enough oil flow on that bearing. As a result, the oil feed line to that bearing begins to coke and that is akin to getting a clogged artery of ones heart. Imagine that failing in flight. That bearing alone has its own dedicated chip detector and usually (not always) is why the Turbomecca 1D1 engine gets a “chip” light in flight. That’s the first place mechanics go when tracking down the cause of that caution-warning light illuminating on the panel. So lesson learned, avoid ground flight idle except for the 30 second cool down when possible. Turbomecca says no more than “5 minutes” at 67-70%. Actually the oil pressure gauge hits “yellow” closer to 70% and less. I’ve found that keeping it at around 71% is better, because it tends to keep the oil pressure “out of the yellow.” But…. If Ng is too high at ground idle (around 74-75% or more), then another issue arises with the Nr (rotor rpm) rising between 300-320 rpm and that’s another bad thing. Per the manual, that too is a “not good” situation as it causes a serious and cumulative damaging vibrating effect on the horizontal tail stabilizer over time. Recap: 30 second cool down at 70% Ng is what you want and then shut down the engine after flight. Or after start-up, move FFCL to 70% Ng, conduct hydraulic accumulator tests and autopilot servo test (if equipped), then immediately move the FFCL all the way into the flight gate. That way you keep engine coking to a minimum.

[@DiveSamCarib]

Wondering why you didn’t turn on the generator at the same time as the fuel pumps. You want to see your GEN light go out before 50% Ng

Ah. I don’t know. Lol I was just along for the ride as a cameraman. I just have limited astar knowledge.

What about the hydraulic checks??
