Smilies Legend
[i]His career included work at Lockheed Aircraft in California and Marietta, Georgia, LTV in Grand Prairie, Texas, McDonnell Douglas in Houston, Rockwell and United Space Alliance in Webster, Texas. He received the Manned Flight Awareness Honoree Award from NASA and the Silver Snoopy Award from the Astronauts for his work on the approach and landing phase of Shuttle Flights.[/i]
[i]At our Flight Techniques meetings, Alan was a frequent presenter showing what had been learned, advising of the best techniques. At one period we experienced a number of landings that were shorter than desirable - still on the runway, but consistently closer to the threshold than comfortable. Alan analyzed hundreds of combinations of factors over a several dozen landings looking for correlations. Nothing seemed to correlate, except one: "If you cross the threshold low, you are likely to touch down short." Now that may seem obvious in retrospect. If a glider comes in low, any pilot would intuitively expect a short touchdown. But it was only obvious in retrospect. And any number of other correlations that common sense might have suggested were simply not borne out by the data. So we called this "Hockstein's Law": If you cross the threshold low, you will touch down short. The entire community worked very hard with the pilots to improve techniques to be higher at threshold crossing and thereby the incidence of short touchdowns was significantly reduced.[/i]
