John Hurst told me that his cruising altitude on his way to Seattle in the 914 motorglider was 17500 C to stay below 18 for VFR.
I wonder if he used oxygen.

Hi Ira
Thx. for the reply.
As far as altitude ceiling I was thinking there may be some limit on something that may perhaps expand and give problems with airframe?? Extra dosage of UV that paint may not be able to effectively block? Something unique to long wings that is not happy at very high altitude? For certain the bags of potato chips in the cockpit will expire before the airframe does from lower pressure at altitude. Perhaps with 914 that still has the ability to make some BTUs at altitude compared to a richer running normally aspirated 912S C something under the cowl over temps due to the lesser amount of air molecules in the same volumetric flow?
I have a stock 914 except for intercooler and ability to lean C I would imagine with long wings C Airmaster and leaned C FL210 is attainable? If wave assisted much higher.

Hi Ira,
I was wondering if your 14k estimate was based on the engines ceiling
or Vx=Vy. I can offer a couple of data points. I typically fly long
cross county flights at 12k to 16k, depending on winds and what ATC
makes me do. I have taken it to 18k once, but I didn't go higher
because I don't have an intercooler or temperature monitoring on the
carburetor inlets. I will be doing this as one of my many winter
projects.
I can share some anecdotal information which I haven't confirmed. I
did hear that Jimmy Thursby took the demonstrator up to 23k, and there
was a guy out in California (can't remember his name, Dennis ??) that
claimed to cruise in the low 20's. From memory both of these
aircraft have Whirlwind propellers on them which have significantly
better airfoils than the Warp drive blades.

after 12k, due to the Warp drive propeller, and after about 14k, I
|
start using oxygen at faster rate, so unless "wind gods" entice me
higher I don't go there!
Cheers, Paul

guess the service ceiling for my plane is around 14k DA
