Patent number: 6285926Abstract: A selected hover altitude deviation display and method for displaying the difference between the current altitude of an aircraft and a selected hover altitude on a multi-functional display unit that includes a compass rose and an aircraft symbol. An altitude sensor generates current altitude data, which is transmitted to a computer processing unit together with a selected hover altitude. The selected hover altitude is determined by the pilot of the aircraft. The selected hover altitude is displayed as a static, analog symbolic representation on the multi-functional display unit. The hover altitude deviation is displayed as a dynamic, analog symbolic representation of the difference between the current altitude of the aircraft and the selected hover altitude. With the selected hover altitude deviation display, the pilot can readily see if his aircraft is above or below a selected hover altitude without relying on external visual reference cues.Type: GrantFiled: April 28, 2000Date of Patent: September 4, 2001Assignee: Rockwell CollinsInventors: David J.

Patent number: 5982300Abstract: A device for indicating that an airplane has reached a safe speed in the presence of headwinds for initiating take-off rotation. The device senses the true ground speed of the airplane and converts the true ground speed into an "indicated ground speed" in accord with the relationship between true air speed and indicated air speed for the airplane. The device subtracts the indicated ground speed from the indicated air speed of the airplane to determine the amount of the headwind and, whenever the headwind exceeds a preselected margin, the device increases the value of the safe minimum indicated air speed for initiation of take-off by any excess of the headwind over the preselected margin. The device then directs the flight director to initiate take-off rotation when the indicated air speed of the airplane equals or exceeds the adjusted minimum indicated air speed.Type: GrantFiled: November 1, 1993Date of Patent: November 9, 1999Assignee: Safe Flight Instrument CorporationInventor: Leonard M.

Patent number: 5916297Abstract: An improvement to an aircraft flight management system automatically allows changes entered into one control display unit (CDU) to be transmitted to the remaining CDU's upon failure of the onboard flight management computers. Each CDU includes memory allowing it to store the initial flight plan as being implemented by the flight management computer. Upon failure of all onboard flight management computers, detection of the failures by the CDU's initiates an alternate navigation mode. In this mode, entries made by a flight crew in one CDU are automatically transmitted to the remaining CDU's and, correspondingly, to the navigation displays, to thereby avoid redundant data entries in the remaining CDU's of a new, modified flight plan. In addition, all navigation displays are automatically caused to display the new, desired flight plan.Type: GrantFiled: April 24, 1996Date of Patent: June 29, 1999Assignee: The Boeing CompanyInventors: John C.

Patent number: 5893040Abstract: An avionic system (102) in which engine thrust rating data is transmitted from electronic engine controllers (108a and 108b) to flight management computer/thrust management computers (120a and 120b) via digital data buses (110a, 110c, and 114) is disclosed. The flight management computer/thrust management computers (120a and 120b) select the proper data set for the specified engine thrust rating upon power-up. If the thrust rating changes, the flight management computer/thrust management computers (120a and 120b) select a new data set corresponding to the new thrust rating as received over the digital data bus (110a, 110c, and 114). This is accomplished without the need to change aircraft wiring. The flight management computer/thrust management computers (120a and 120b) store the thrust rating in nonvolatile memory (126), allowing the flight management computer/thrust management computers (120a and 120b) to use the stored value to initialize relevant settings according to current engine thrust rating.Type: GrantFiled: May 15, 1996Date of Patent: April 6, 1999Assignee: The Boeing CompanyInventors: Peter D.

Patent number: 5823479Abstract: A method modifying the landing pitch attitude of an airplane during landing approach and touchdown is disclosed. A reference value for a predetermined flight condition parameter is subtracted from a current value of the predetermined flight condition parameter, resulting in a difference value. Based upon the difference value, a schedule determines a corresponding deflection value for a movable surface capable of producing lift. The movable surface is automatically deflected to an amount equal to the deflection value.
