Lessee here Shawn.....if I creep the thing up to the edge of the deck...or scoot off over the edge...if my memory is anywhere near correct....I am unfortunately in the shaded part of the WAT Chart no matter what I do...and if the aircraft has more than nine pax...or seats for more than nine....and even if I use Cat A as you suggest....me thinks we still have a problem....am I correct in assuming that? Now does the WAT chart only apply to takeoffs over firm, smooth, surfaces....which oceans are not....gosh...maybe there is no legal way to make an offshore takeoff.
Can you enlighten me just a bit more here , Shawn? But of course we must never violate the limitations section of the flight manual while aviating....got any suggestions, flight profiles, weights, airspeeds, or something that will advance this thread, Shawn?
