Brian: I have had a 172 to 12,500 more than once and a 182 to more than 15,000 ft traversing the San Gabrial mountains over Mt. Baldy in So. Calif. On my trips back to CA from the midwest I would routinely go up to 12,500 traversing the ridge between Las Vegas and Santa Fe NM. I also have made many trips to Prescott AZ from So. CA that required altitudes above 10,000 ft to give comfortable terrain clearance in the often turbulent air between Prescott & the Colorado River at Parker and Lake Havesau City AZ. I have personally determined the service cieling of a 172 to be between 14,000 & 14,500 ft so at 12,500 I would be crowding its capability pretty good
I know that the Sport Plane regs say 10,000 ft but that in high country can get you in a lot of trouble if you are held to it. Perhaps the whole idea is to keep Sport Pilots out of high country. Personally I never had a problem up to the 12,000 altitude for a sustained period but I am not a smoker and do not have a breating problem and 10,000 ft has always been the recomended cieling for smokers.
