  • Method and system for detecting forces on aircraft
    Patent number: 9327842
    Abstract: A method for sensing a takeoff of an aircraft includes receiving a rate of change in vertical motion of the aircraft, determining whether the rate of change in vertical motion of the aircraft exceeds a first threshold, integrating the rate of change in vertical motion of the aircraft and outputting a virtual altitude signal, responsive to receiving the indication that a portion of the aircraft is contacting a surface, delaying the virtual altitude signal through a discrete low pass filter and outputting a delayed virtual altitude signal, subtracting the delayed virtual altitude signal from the virtual altitude signal to output an altitude perturbation signal, determining whether the altitude perturbation signal exceeds a second threshold value, and outputting an indication that the portion of the aircraft is not contacting the surface responsive to the rate of change in the vertical motion of the aircraft and the altitude perturbation signal.

  • Method and system for detecting forces on aircraft
    Patent number: 9026377
    Abstract: A method for sensing a force applied to an aircraft includes receiving a derivative of the acceleration of a motion of a portion of the aircraft, determining whether the derivative of the acceleration of the motion of the portion of the aircraft exceeds a threshold, and outputting an indication that a force has been applied to the portion of the aircraft responsive to determining that the derivative of the acceleration of motion of the portion of the aircraft exceeds the threshold.
