Engine Monitors

[@pritchettaviation1120]

This has to be the most useful video on all of KZbin, thanks for posting!

[@mdickinson]

Excellent information - this video should be required viewing for every GA owner who has an engine monitor!

Thank you sir for posting this video lesson!

i dont mean to be off topic but does any of you know a method to get back into an Instagram account? I stupidly lost the account password. I appreciate any help you can give me!

[@mitchellroger1924]

@Gunner Brennan I really appreciate your reply. I found the site thru google and Im trying it out atm. Takes a while so I will reply here later when my account password hopefully is recovered.

Can somebody point me to the Lycoming service bulletin that talks about leaning during the runup? Mike mentions it at 18:25.

[@DIYPackraft]

I cannot, but Mike has done at least two webinars specifically focused on leaning and I recall him mentioning it in them, so check those out if you haven’t already found the SB.

[@Echo.Yankee]

See page two of this article. It is mentioned there. SB No.1132B resources.savvyaviation.com/wp-content/uploads/articles_eaa/EAA_2010-12_the-mag-check.pdf

Fantastic information.

Mike: What causes the preignition or thermal runaway that occurs suddenly reaching 500 degrees or more and within two minutes?

[@5128goldenrod]

Hey mike, the BPPP recurrent engine training encourages us to not ru. The IO520 below 2300 rpm due to harmonic stress on the engine.....if my 3 blade prop that is well balanced..... is this a concern to you? (Reference highest mo/ lowest rpm strategy).....if i am just goofing around locally doing a sunrise cruise, i do 21-2200 rpm with 21 inches LOP, to get 10.5 gph LOP and 260degree CHTs.....is this bad practice for the engine?

As someone who does dynamic prop balancing with a background in engine vibration research, you raise an interesting topic. I won't presume to encroach on Mike's tutorial here, but I will say that in an age where we have digital monitors, I believe that for advanced GA aircraft I'd love to see onboard _vibration_ monitors. If you ever see a stiff, low mass composite airframe with instruments so blurred by vibration at certain resonant RPM bands and with control pushrods vibrating like bass guitar strings, you'd blanche. Dangerous? You betcha. Most airplanes don't have such high risk occurrences, but they are becoming more common, and even less aggressive vibration should be tuned out because it _is_ damaging over time. With a monitor, you can catch such things early. Even if it's just a data logger that the accelerometers report to so they can be examined later (no panel space taken up), it's a lot of peace of mind for the bucks.

@@craigwall9536 Insight makes such a monitor. I have one installed in my plane. It’s called G3 and has x y z acceleration logged. The accelerometer is mounted on top of engine case. As to Andy’s question ops below 2300 with that prop should be avoided as there is indeed a harmonic issue at around 2100-2200 so the 2300 limit was placed.

Sorry...big snoozer. But I have say, you know your craft!
