More on AF 447 LOC: Stability, Vg/Vn Diagram and Recovery

There is another very important aerodynamic engineering issue that needs to be discussed when Loss of Control is the subject, and that is Stability, as it relates to high angle of attack flight. Transport category aircraft may not have the same “forgiving” stability as training aircraft, when it comes to bringing the aircraft back intoContinue reading “More on AF 447 LOC: Stability, Vg/Vn Diagram and Recovery”

AF 447: High Altitude Stall or Swept Wing Stall? Did the Mishap Investigation Boards Make a Fundamental Aerodynamic Error?

The mishap investigation boards have given a less than aerodynamically correct presentation of “high altitude stalls” in the 2009 Loss of Control LOC mishap investigation of AF 447 and theĀ  2005 Loss of Control LOC mishap in Venezuela of a West Caribbean Colombian MD82. The result is that these mishap investigation reports are not puttingContinue reading “AF 447: High Altitude Stall or Swept Wing Stall?
