Bloop What are examples of software that may be seriously affected by a time jump? I was surprised to discover recently that if you put some aircraft designers in a room, or in my case on an internet forum, and ask them: What wing planform is best for a typical ultralight? you will kick off quite a lively and passionate discussion with the burning issue being the compromise between lift distribution, ease of construction and stall behavior. Aviation Stack Exchange is a question and answer site for aircraft pilots, mechanics, and enthusiasts. Before I can answer that question some basic aerodynamic theory required lets talk wing lift coefficients.
