I 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. Pete From: William A. Hogarty [mailto:billhogarty@gmail.com]

Subject: Re: [LML] FL270 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. |
