When I first flew the 737-200 back in 1976 Boeing supplied the runway analysis charts at our company request. We operated from coral strips in the Central and SW Pacific region. The take off settings available were flaps 1,2,5,10, 15 and 25. Boeing recommended at the time we use Flap 10 for all take off's using Improved Climb (V2 Overspeed) for heavier weights runway length permitting. Their point was it would be all too easy to inadvertently select the wrong flap setting when the choice was six of them. Anyway, a choice of six runway analyses for one runway was going overboard.
