Abstract
An aircraft performance instrument which provides a first indicator which represents the line of level flight of the aircraft and a second indicator representative of the maximum permissible angle of attack of the aircraft.
Claims7
An aircraft instrument especially useful for providing guidance to the pilot of an aircraft when encountering windshear during a take-off or a go-around phase of flight, comprising:
- (a) a scale index, located on a circular dial face;
- (b) flight path angle signaling means for providing a signal representative of the aircraft flight path angle;
- (c) path means for displaying, relative to said scale index, the aircraft flight path angle, said path means comprising a pointer driven by said signal representative of the aircraft flight path angle, said pointer being pivoted about the center of said dial face;
- and
- (d) stall means for displaying, relative to said pointer, the aircraft stall margin.
2 more elements
An aircraft instrument for indicating the performance margin of the aircraft during take-off or a go-around phase of flight and for assisting the pilot of the aircraft in responding to a windshear encounter, comprising:
- (a) flight path angle means for displaying the flight path angle of the aircraft relative to a scale calibrated in degrees;
- and
- (b) maximum angle of attack means for displaying relative to said scale and said display of said flight path angle the margin to the maximum permissible angle of attack, said maximum angle of attack means being driven by a Stall Warning System which operates in response to aircraft flight parameters.
