<p>BillWilson: /* Remembering Bob Steward */</p> <hr /> <div>== Remembering Bob Steward ==<br /> <br /> Bob passed away April 23, 2014, after a brief illness. Your memories of Bob Steward are welcome here.<br /> <br /> == Remembering Bob Steward ==<br /> Bob is my older brother, and he taught me both the automotive trade, as well as a love of aviation. He shared his time, talents, interests and helped mold and shape my career path into where I am today. If not for him, I would not be the man I am today! His love of flying, working with all things mechanical, and more importantly his devotion to providing service to others in their time of need is a great example that I hope to be able to live up to one day. Bob, you will be missed! - Dave Steward<br /> <br /> The value that Bob Steward brought to the aviation - and specifically, Grumman - communities was vast and wide-reaching. The void left by his passing will likely never be filled.<br /> <br /> Bob was a damn fine man, one of the finest I'll ever met. - Greg Amy<br /> <br /> One of the finest men I've ever met. I feel the loss already. - Joe Campbell<br /> <br /> Bob taught me the real difference between mechanic theory and real practice. I will miss being able to have discussions with him on some of the finer points. <br /> <br /> I remember with great fondness the call I got right after an event in 2001 at Blue Ash, when Bob called and asked if I could go and retrieve Gwen's portable rocker. Bob and I tried 5 different times to both make flyins where I could return the chair. I started logging the flight and stops on the chair with a Sharpie. It was not until Cody in 2002 that I could return it with many frequent flyer miles. I have many such stories of Bob and the times he stayed after to help planes get home. My heart is just refusing to believe what my mind has accepted. To live a life like his would never be a wasted life. Blue Skies - Roscoe<br /> <br /> Bob was a valued friend, a Master Craftsman, fellow aviator and enthusiast. He was the fastest sheet metal craftsman I have ever seen and when he was in the zone, there was never a move wasted. I had talked to him earlier in the year about some problems, and he was quick with both advice and offers of help. His passing makes the world a lesser place. - Scott Jernigan<br /> <br /> Bob was a wonderful human being, having the best traits of knowledge, wisdom, passion and generosity. He would spend countless amounts of time sending detailed e-mails to help the Grumman owners and pilots out. Thank you, Bob. -Bill Wilson</div>

<p>BillWilson: /* Use of Partial Flaps For Takeoff */</p> <hr /> <div>== Factors Influencing Ground Roll ==<br /> <br /> For propeller-driven aircraft, takeoff distance has been shown to be nearly proportional to wing loading (aircraft weight divided by wing area) and inversely proportional to the density ratio (actual density divided by sea level density), power-to-weight ratio, and the maximum takeoff lift coefficient.<br /> <br /> == Effect of the High Compression STC, PowerFlow Exhaust, and Sensenich Propeller ==<br /> <br /> As stated in [[Basic Engine and Propeller Performance]], the improvement in thrust power from the [[High Compression STC]] at speeds consistent with the takeoff roll is about 10%. Since takeoff distance is inversely proportional to power, takeoff distance will be reduced by about 10%. To determine the effect of exhaust and propeller improvements, those increments would have to be added to the engine curves as discussed in [[Basic Engine and Propeller Performance]] and new RPM equilibrium points found. But like the [[High Compression STC]], the result is more thrust power than the increase in brake power would indicate.<br /> <br /> == Use of Partial Flaps For Takeoff ==<br /> <br /> Discussion about the use of partial flaps for takeoff can be found in [[Normal Procedures]]. While some claim that takeoff performance improves, measured takeoff distance performance actually varies per conditions. There is definitely a pitch attitude change beyond 1/3 flap deflection in an AA5x, that may feel more comfortable for some, and the use of flaps may improve angle-of-climb performance. There are only Ron Levy's and Bill Wilson's flight test flights that have been published in the AYA Star.</div>
