Posted by cortelyounext on Tue Jul 9 12:55:01 2013, in response to Re: Investigation focuses on possible pilot error in crash landing of South Korean plane, posted by Dave on Mon Jul 8 17:29:50 2013. Good discussion. The only thing I respectfully take umbrage or hubris whichever one of those words means issues with is with respect to airspeed and attitude control . The pitch controls airspeed, power controls descent rate is more related to propeller aircraft. Airspeed as a function of power and descent of pitch is a more accurate aerodynamic model when related to turbine powered aircraft. Without getting into detail, the reasons have to do with prop wash, inertia, and other factors. As an aside, the 737NGs fly faster on final than most if not all airliners to include the wide bodies. The landing technique in terms of power reduction sounds similar to 777 particularly with crosswinds. There are a couple three techniques to land in crosswinds but the one I prefer is to kill the drift or crab on final and align the aircraft down the centerline once "over the numbers" entering ground effect. At that point, the flight spoilers are actuated so lift as well as airspeed, albeit to a lesser extent, are destroyed so if you retard the throttles at the "normal" point you are going to hit hard. To better illustrate my point, here is a picture of a crab, and thanks. |
