Pitch guidance system

A pitch guidance system for an aircraft, comprising:

• means for providing a pitch angle reference signal representative of the optimum pitch angle for maximum climb of the aircraft;
• means for providing a signal representative of the altitude of the aircraft;
• means for providing a signal representative of the vertical speed of the aircraft;
• means for providing a signal representative of the pitch angle of the aircraft;
• means responsive to said pitch angle signal and said pitch angle reference signal for providing a pitch angle guidance signal for maneuvering the aircraft;
• and
• means responsive to said itch angle reference signal, said altitude representative signal and said vertical speed representative signal for modifying said pitch angle reference signal in response to said pitch angle reference signal, said altitude signal and said vertical speed signal.

A pitch guidance system for an aircraft, comprising:

• means for providing a pitch angle reference signal representative of the optimum pitch angle for maximum climb of the aircraft;
• means for providing a signal representative of the altitude of the aircraft;
• means for providing a signal representative of the pitch angle of the aircraft;
• means responsive to said pitch angle signal and said pitch angle reference signal for providing a pitch angle guidance signal for use in maneuvering an aircraft;
• and
• means responsive to said altitude signal and said pitch angle reference signal for modifying said pitch angle reference signal in accordance with the altitude signal.

A guidance system for aircraft comprising:

• means for providing a pitch angle reference signal;
• means for providing a signal representative of the pitch angle of the aircraft;
• means for providing a stall warning signal;
• means responsive to said pitch angle signal and said pitch angle reference signal for providing a pitch guidance signal for manuevering an aircraft;
• and
• means responsive to said pitch angle reference signal and said stall warning signal for modifying said pitch guidance signal in accordance with said stall warning signal.

An aircraft guidance system comprising:

• means for providing a pitch angle reference signal representative of the optimum pitch angle for maximum climb of the aircraft during a wind shear;
• means for providing a stall warning signal;
• means for providing a signal representative of pitch angle of the aircraft;
• means responsive to said pitch angle reference signal and said pitch angle representative signal for providing a pitch guidance signal;
• means responsive to said stall warning signal for modifying the pitch angle reference signal to provide a modified stall warning signal upon the occurrence of a stall warning;
• and
• means responsive to the pitch angle signal and the modified pitch angle reference signal for providing pitch guidance information to the pilot during a wind shear.
