Safest, most redundant oxygen setup for single pilot or dual occupant in the FL's?

It happens. I limit myself to FL180 unless there is a compelling reason to go higher.

I was actually behind the plane enroute to ACY it was a somber weekend after that occurrence. I believe he was. Dentist and his plane was fresh out of annual and lost contact with ATC shortly after leaving Michigan I believe

On the topic of steep idle descents, shock cooling is a myth but ring flutter is not! This is why both engine manufacturers talk about never doing a closed throttle descents but maintain a minimum amount of power of at least 15” to prevent the air from turning the prop rather than the engine turning the prop. Having the prop turn the engine reverses the stress on the rings and can damage them on a prolonged descent. The immediate symptom right after such damage will be much elevated oil consumption. Recall one pilot that did an emergency descent from flight levels to an airport below him with closed throttle and opted to overhaul soon thereafter. Of course depending on the nature of the emergency, the engine may be the least of your concerns.

Above though @Will.iam talks about the proper safe way to do an emergency descent without risking damage to the engine above.
But the other concern for engine management is don’t go to full power immediately if you go around, just use enough power to maintain level flight as oil temp and CHT comes back as you fly over the runway and by the departure end temps will be good off to go to high power.

Will admit I hadn’t come across ring flutter yet. Did some googling and found a few high level paragraphs from Lycoming and a handful of forum threads, but didn’t turn up anything more in depth (was dreaming of something akin to the Pelicans Perch articles on LOP, etc). Any chance you have any articles on this?

 

Apologies for thread drift

This timely video popped up from one of my favorite EXP guys. He gives a nice walkthrough on the issues and does a little flight test of one of the portable generators. Worth the watch and I am impressed at the results he got with a relatively cheap device and just using a cannula.

My point was, such mishaps would not go un-noticed or not detected.

VFR flights in the teens might, but your TOC is much longer below 18,000

Sure!   I remember!  The EMT has a switchable regulator so you can turn it on and off.  The PrO2's have an activation key that starts the flow and continues until empty in the event of a decompression event.  The PrO2 also comes with more options on cylidner size and number of users....

Coming back to FL any time soon?

Thanks for the info.

I will be there for Mooney Summit.   Will you be there?
