Claim 9

Apparatus for controlling an aircraft having multiple control surfaces, comprising: a control handle for supplying pilot-entered manual inputs to the control surfaces to initiate a change in aircraft attitude; an automatic control unit for receiving at least one of roll, pitch and yaw signals to establish a desired aircraft trajectory and for supplying at least one of roll, pitch and yaw signals to the control surfaces to maintain the aircraft on the desired trajectory; and a multi-position switch mounted on the control handle exclusively for generating commands in response to pilot input to selectively increase and decrease the at least one of roll, pitch and yaw signals supplied to the automatic control unit; thereby changing the desired trajectory.

Claim 10

Apparatus for controlling an aircraft having multiple control surfaces, comprising: a control handle for supplying pilot-entered manual inputs to the control surfaces to initiate a change in aircraft attitude; an automatic control unit for receiving at least one of roll, pitch and yaw signals to establish a desired aircraft trajectory and for supplying at least one of roll, pitch and yaw signals to the control surfaces to maintain the aircraft on the desired trajectory; and a multi-position switch mounted on the control handle exclusively for generating commands in response to pilot input to selectively increase and decrease the at least one of roll, pitch and yaw signals supplied to the automatic control unit; thereby changing the desired trajectory.

Claim 11

Apparatus as recited in claim 8, wherein the automatic control unit generates displays to communicate required manual control inputs to achieve a desired trajectory.

Claim 12

Apparatus for controlling an aircraft having multiple control surfaces, comprising: a control handle for supplying pilot-entered manual inputs to the control surfaces to initiate a change in aircraft attitude: an automatic control unit for receiving signals to establish a desired aircraft trajectory and for supplying signals to the control surfaces to maintain the aircraft on the desired trajectory; and a multi-position switch mounted on the control handle for generating commands in response to pilot input to selectively increase and decrease the signals supplied to the automatic control unit; thereby changing the desired trajectory, wherein the multi-position switch comprises a first momentary-contact activation axis having first and second switch contacts for respectively generating INCREASE and DECREASE commands, a second momentary-contact activation axis having first and second switch contacts for respectively generating INCREASE and DECREASE commands, and a third momentary-contact activation axis having a single switch contact; the first, second, and third axes being mutually perpendicular.

Claim 13

Apparatus for controlling an aircraft having multiple control surfaces, comprising: a control handle for supplying pilot-entered manual inputs to the control surfaces to initiate a change in aircraft attitude: an automatic control unit for receiving signals to establish a desired aircraft trajectory and for supplying signals to the control surfaces to maintain the aircraft on the desired trajectory; and a multi-position switch mounted on the control handle for generating commands in response to pilot input to selectively increase and decrease the signals supplied to the automatic control unit; thereby changing the desired trajectory, wherein the multi-position switch comprises a first momentary-contact activation axis having first and second switch contacts for respectively generating INCREASE and DECREASE commands, a second momentary-contact activation axis having first and second switch contacts for respectively generating INCREASE and DECREASE commands, and a third momentary-contact activation axis having a single switch contact; the first, second, and third axes being mutually perpendicular.

Claim 14

Apparatus for controlling an aircraft having multiple control surfaces, comprising: a control handle for supplying pilot-entered manual inputs to the control surfaces to initiate a change in aircraft attitude; an automatic control unit for receiving signals to establish a desired aircraft trajectory and for supplying signals to the control surfaces to maintain the aircraft on the desired trajectory; and a multi-position switch mounted on the control handle for generating commands in response to pilot input to selectively increase and decrease the signals supplied to the automatic control unit; thereby changing the desired trajectory; wherein the automatic control unit stores the commands generated by the switch without activating the entered change in desired trajectory; and wherein the switch comprises a switch position for receiving a pilot-entered ENABLE signal to activate the entered change in desired trajectory.

Claim 15

Apparatus for controlling an aircraft having multiple control surfaces, comprising: a control handle for supplying pilot-entered manual inputs to the control surfaces to initiate a change in aircraft attitude; an automatic control unit for receiving signals to establish a desired aircraft trajectory and for supplying signals to the control surfaces to maintain the aircraft on the desired trajectory; and a multi-position switch mounted on the control handle for generating commands in response to pilot input to selectively increase and decrease the signals supplied to the automatic control unit; thereby changing the desired trajectory; wherein the automatic control unit stores the commands generated by the switch without activating the entered change in desired trajectory; and wherein the switch comprises a switch position for receiving a pilot-entered ENABLE signal to activate the entered change in desired trajectory.

Claim 16

Apparatus as recited in claim 11, comprising a display unit connected to the storing means for graphically displaying a representation of the change in trajectory commanded by inputs to the switch.

Claim 17

Apparatus as recited in claim 12, wherein the display unit displays a first representation of the change in trajectory commanded by inputs to the switch prior to entry of an ENABLE signal and a second representation of the change in trajectory commanded by inputs to the switch after entry of an ENABLE signal.
