  • Aircraft flight command and display system
    Patent number: 4763266
    Abstract: A system particularly adapted for guiding aircraft through wind shear conditions includes: a thrust command control (10) for maintaining airspeed and groundspeed within a defined range; a detection system (12) for detecting and annunciating the presence of moderate and severe wind shear; and a pitch command system (14) which provides pitch command signals for optimum climb out from a wind shear condition.
    Type: Grant
    Filed: December 27, 1982
    Date of Patent: August 9, 1988
    Assignee: The Boeing Company
    Inventors: Larry R. Schultz, Peter J. Super, Francis J. van Leynseele
  • Apparatus for determining the groundspeed rate of an aircraft
    Patent number: 4646243
    Abstract: Aircraft gyro (20, 22) signals .theta. and .phi., representative of pitch and roll attitude, respectively, and accelerometer (24, 26, 28) signals a.sub.x, a.sub.y, a.sub.z, representative of longitudinal, lateral, and normal acceleration, respectively, are processed (30, 32, 34, 36, 38, 40) to produce signals a.sub.GSLO, a.sub.GSLA, and a.sub.GSN, representative of the longitudinal, lateral, and normal groundspeed rate components, respectively. The component signals are summed (50) to produce a signal representative of total aircraft groundspeed rate.
