  • Apparatus and method for determining information for aircraft
    Patent number: 6940425
    Abstract: The present invention provides a method for determining information for an air vehicle including the steps of providing a first coefficient of pressure data point, providing a situation involving the air vehicle, deriving pressures during the situation and deriving a second coefficient of pressure data point from the pressures derived during the situation, and defining a line passing through the first and second coefficient of pressure data points, whereby a selected coefficient of pressure data point on the line corresponds to the information. The invention encompasses apparatus for accomplishing the method. In some embodiments, the information relates to angles from zero lift and/or zero yaw.

  • Apparatus and method for measuring and displaying angular deviations from angle of zero lift for air vehicles
    Patent number: 6271769
    Abstract: The present invention provides a flight instrument apparatus and method for its use in air vehicles having an indicator visibly displaying angles from zero lift and having a data port for electrically exporting angles from zero lift wherein pressures from wing ports and pressures from the pitot and static ports of air vehicles are sensed, converted to digital data and mathematically divided one into the other to give a coefficient of pressure which varies uniquely with angles from zero lift of the air vehicle and which is used to calculate the angular deviation from angle of zero lift using a known relationship between the coefficient of pressure and the angular deviation from angle of zero lift.
