As a matter of gratuitous curiosity, is this thread some sort of record for PPRuNe at 110 pages ( not counting the many deleted threads at the beginning) or have we done other subjects even more to death.
BTW, I don't include the good info such as that by justme69 in the " done to death" tag, I think you have done a sterling job, and even if it is not your field, you have grasped the subject matter of this far better than some who would believe themselves in some way "knowledgable".
