Very true. My point was that dive shops are accustomed to selling pure oxygen, not necessarily blended with air or air+helium.

Deco tanks are 50/50 or pure oxygen. 100% is also used in diving rebreathers.

Vent lever pulled, window open (unless you are in a screaming descent; limitation is 150 mph), roof air scoop open. Frozen water bottles. Not much else you can do..

That's all good and fine until your A&P calls you saying that your J-bar has just snapped in half..

The only time is does matter is when ATC requests "120 knots or greater"

Yeah, same here, although I am paying with a 0.4 gph ff increase for those 2-3 knots. Essentially, a torn boot in an E/F is an equivalent of a permanently not-quite-fully-open, not-quite-ram air, plus the obvious consequences of rubber chunks entering the induction system.

No. By design, the boot is downstream of the point where ram air joins filtered air. You could potentially delete ram air functionality by welding shut the ram air door and/or removing the ram air door cable, but the intake boot will still be needed. @cliffy is correct about the rotational movement and vibration of the engine, especially during start and shutdown, being the reason behind the boot design as it is.

Do tell, do tell!!

I passionately despise "flowing lines" of any kind. Your Exhibit 1 has a lot of potential though. Lose the curls and add a splash of bright color somewhere. Either orange or cold/lemon yellow would look pretty good with those grays.

Curious. My celebratory gunfire invariably hits my hangar buddy's Cirrus...

I am really enjoying GP so far. Love having secondary on-screen engine monitor capability. Hate the tiny (i) button to pull up complete airport info

Wowzers!! The only missing redundancy is a backup autopilot!

One of the Commissioners requested info on G100UL alternatives. KRHV supervisor did talk about Swift 100R and the VP Racing Fuels developments, but unfortunately omitted that 100R has been in 172R fuel tanks for >8 months now at KSQL.
