Purpose for Asking??
212, good point. The 15K altitude limit in the original manual is not a service ceiling, but is the enroute altitude limit which was certified. Thus, as I mentioned, SA performed all of the flight loads, handling qualities, power train etc testing prescribed in AC 29.2b ( I think rev c came afterward ). Just as aside, in preparation for a Portuguese Coast Guard program that never happened, we in fact did a flight loads survey at 31k+ lbs up to 9000ft.
Perhaps the poster of the original question could explain what he is looking for and why. There are no clues from what has been posted. The first post says that the 92 has a service ceiling of 15K, which is not what the flight manual says, and his subsequent posts include various sources defining service ceiling, so he apparently is familiar with the term.So, what is this about? Writing a spec for a new machine? Writing test requirements for a government entity? Trying to write a requirements document for a competitive source selection group so that it disqualifies one candidate in favor of another? Generating info for a school paper? Haven’t a clue.
