Glide distance
In a different life, I had experience in engine out operations both in military jets and civilian prop aircraft. Those CAFE results are very interesting, but rather than discuss glide ratios, it might be easier in the heat of the moment to visualize it all as miles/1000ft. The only time that this knowledge is particularly useful of course, is when the engine quits. This is when the adrenalin may be a little higher than usual, so it is best to have an easy number to aim at. What we are looking for then, is the best lift over drag speed, theoretically for a specific weight, but from a practical standpoint figure out a good glide speed which will be about VY or a touch less, and STOP the prop. The CAFE charts mention TAS but what we are interested in is IAS. It is always better to err on the plus side of speed rather than being slow, because induced drag builds up very quickly. Many folks have got themselves in a pickle by trying to STRETCH the glide. This cannot work!
As a matter of interest since someone mentioned it, all of the conventional swept wing jets that I tested have a glide ratio of a touch under 3 miles/1000 ft. At about 230kts. Strange but true....ish. That held true from the 707 and others, to single seat fighters.
