The 5 limits discussed are computed
John,
The 5 limits are computed and the most restrictive is applied is the point I am making. Probably very few of us have heard about these things let alone understand them or how to calculate them. The point is to raise awareness and understanding. You don't have to be a surgeon to put a band aid on a wound. But you should also be smart enough to realize a band aid will not cure a gaping gun shot wound. As pilots we have a lot of knowledge but that doesn't mean we know everything. The FARs are a mess! Very few are truly stand alone consequently we have a tangled mess. Think about fuel requirements, alternates, and who can fly with whom. 30 or 45 minutes, better than 2,000 &3 plus or minus 1 don't need one, and anybody can fly with anybody! Not quite so fast!
