I thought the cabin pressure relationship, 8,000' cabin at FL280 was
the emphasis in the manuals. Of course, that presents an interesting
question: "What will be the airframe limit for N540TF?" It has 600
hp, and is supposed to be able to maintain sea level power to FL220.
Hmmm

believe the service ceiling is FL280. I have had my ES-P up
that high twice. While it was a slow climb above FL250, it
was still well over 100 ft/min at FL280. You IV guys should
have no problem getting that high. I think only RVSM limits
you from going higher.

Someone told me that the "service
ceiling" is defined as point at which the aircraft, at
full power, cannot maintain
Another someone mentioned that the IV-P
was limited in altitude by engine parameters. If that is
correct, then each
aircraft would probably vary in max
altitude by builders skill and technique in building.
Finally, he who builds the lightest
plane with the minimum accessary drag and the tightest
cowling, might be the winner.
..........sounds like it might be an
interesting competition.
