    摘要: Disclosed is a method of and apparatus for determining the flare height at which the flare maneuver of an automatic landing procedure is initiated. The method includes the step of generating an adjusted approach sink rate signal, which depends on the ground speed of the aircraft during a landing approach and is compensated for short term deviations from the glideslope angle. The adjusted approach sink rate signal is filtered (first order lag), and the filtered signal is then used to establish: (a) a nominal flare height value when the aircraft sink rate is between two predetermined sink rate values (the aircraft landing approach speed is in a nominal range); (b) a flare height that is above the nominal flare height value and is linearly related to the adjusted approach sink rate of the aircraft when the adjusted approach sink rate exceeds the first predetermined value (relatively high ground speed approach); and (c) a flare height that is less than the nominal flare height value and is linearly related to the magnitude of the adjusted approach sink rate signal when the magnitude of the filtered adjusted approach sink rate signal is less than the second predetermined sink rate magnitude (relatively low ground speed approach). In the disclosed arrangements, provision is made to limit the flare height determined by the invention to maximum and minimum flare height values and provision is made for storing the flare height signal for use by the automatic landing system after the flare maneuver has been initiated.

    摘要: Disclosed is a method of and an arrangement for real time estimation of the location of the center of gravity of an aircraft. The center of gravity estimate is utilized in an aircraft flight control system for effecting flight control laws in which the center of gravity is a parameter that at least in part establishes open loop compensation or feedback gain. The disclosed method and arrangement are specifically adapted for establishing stabilizer mistrim during a landing procedure in which an aircraft flight control system is automatically controlling the aircraft. The method generally comprises the steps of generating a signal that represents the product of the aircraft stabilizer position and a multiplicative factor, A₁ and adding to that product an additive factor, A₂. The multiplicative factor, A₁, and the additive factor, A₂, both are determined on the basis of the angle of attack of the aircraft and the aircraft flap setting.

    摘要: A controller for generating a bank angle limit for an aircraft during takeoff with an nonoperational engine. The controller operates so that there are minimum and maximum bank angle limits. Between these minimum and maximums, there is a linear relationship between aircraft airspeed and bank angle limit. However, before there is a change in aircraft airspeed from an increasing mode to a decreasing mode or vice versa, the bank angle limit remains constant until the change in aircraft airspeed is greater than or equal to a predetermined airspeed differential.

    摘要: Disclosed is a method of and apparatus for generating a signal representative of aircraft gear altitude after the flare maneuver is initiated in an automatic landing procedure. In accordance with the invention, the gear altitude signal is produced by complementary filtering of the aircraft gear altitude signal and the aircraft inertial vertical acceleration signal, with the complementary filter frequency being varied so that the aircraft filtered gear altitude signal primarily is produced on the basis of the vertical inertial acceleration signals prior to the time at which the aircraft reaches the runway threshold and is primarily produced on the basis of the aircraft gear altitude signal after the aircraft crosses runway threshold. The result is the reduction of the filtered gear altitude signal variation that can be caused by irregular terrain along the landing approach path while maintaining signal sensitivity to runway slope and runway slope variation.
