P-ceiling vs. T-ceiling

Ken,
The FL200 limit is an operating limitation, so it is not approved or legal to fly higher. The cabin altitude in a P337 is 10,000ft at FL200. I am not sure why they limited the P337 this way. The P210N has the same pressurization setup, but can fly to FL230 where the cabin altitude is 12,100ft or so. The R model P210 is approved to FL250, but you must wear oxygen above FL230. It also shares the same 3.35psi pressurization setup.

Thanks for the info. I presently have 3 airplanes for 3 different missions and a P337 would replace all 3 if it could legally go to FL250. That would save a lot in insurance, hangaring, maintenance, etc. (I already know about 337 maintenance with my T337C.)

Is FL200 in the limitations section of the POH? Also, I haven't seen anywhere an FAA definition of "certified ceiling". Where is that found?

Thanks.

Ken

Ken, the limitation is in the Limitations Section of the POH.

I've seen 210 with no problem.
