I would recommend getting the MH oxygen mask with a mike – about $400. It makes you sound like Darth Vader but it means you don’t need to think about breathing, which at FL200+ is pretty critical.
Your SR22 is probably 310 hp, my IO-520 is 285 hp but I’m guessing I’m running at a higher power setting.
You got me confused there Chris. Yours is an A36, which should have an IO-550 (albeit rated at 300hp)..
No, it’s a 1980 A36 with an IO-520BB.
Got the Alps-M mask, thanks Peter!
1500 cu ft O2 bottle being installed now.
Ah sorry, got it. That modern paint scheme was deveiving. But yeah, the panel shows it’s pre ’84…
