Where did the use of L/D (the ratio of lift to drag) to describe a ground referenced flight path angle originate? *I know it has been perpetuated by SeeYou, but did they start it? That goes back to the 50s, very likely. Certainly, it was used on circular slide rule calculators of the 60s (referenced in Sunship Game and articles of the era). L/D *is* a little easier to say than "the inverse of the tangent of the flight path angle", even if it *is* extremely sloppy shorthand. -T8 |
