1. An aircraft flight hazard avoidance system comprising:
- a plurality of flight hazard warning systems wherein each of said systems generates an alert signal indicating a potential flight hazard;
indicator means, responsive to said alert signals, for generating command indications corresponding to said alert signals for directing the operator of the aircraft to avoid said potential flight hazards; and
an alerting system, responsive to at least two of said alert signals generated concurrently, for selecting one of said concurrently generated alert signals for input to said indicator means wherein said selected alert signal represents the most critical flight hazard.

26. A method for providing a alert of a hazardous flight condition for an aircraft comprising the steps of:
-
monitoring sensor data; analyzing said sensor data for a plurality of potential flight hazards; outputting an alert signal according to a predetermined alert schedule when at least one potential flight hazard is detected, and wherein said alert schedule includes a procedure for arbitrating between a multiple of alert conditions as a function of aircraft altitude; and generating command indications based on the outputted alert signal.

29. A method for providing an alert of a hazardous flight condition for an aircraft comprising the steps of:
-
monitoring sensor data; analyzing said sensor data for a plurality of potential flight hazards; outputting an alert signal according to a predetermined alert schedule when at least one potential flight hazard is detected, and wherein said alert schedule includes a procedure for arbitrating between a multiple of alert conditions as a function of anticipated corrective responses to the hazardous flight conditions represented within said multiple alert condition; and generating command indications based on the outputted alert signal.

30. A method for providing an alert of a hazardous flight condition for an aircraft comprising the steps of:
-
(a) detecting if a first hazardous flight condition exits; (b) determining if a second hazardous flight condition exists; (c) comparing said first hazardous condition and said second hazardous condition according to a predefined criterion, wherein said step of comparing further comprises determining if corrective actions to said first and said second hazardous flight conditions are complementary; and (d) issuing an alert based on a result of step (c). - View Dependent Claims (31, 32)

33. A method for providing an alert of a hazardous flight condition for aircraft comprising the steps of:
-
detecting a hazardous condition; determining if a projected flight path associated with an alert of said hazardous condition increases a threat condition of the aircraft; and suppressing an alert of said hazardous flight condition if the flight path associated with said hazardous flight condition increases said threat condition.

34. A device for providing an alert within an aircraft of a hazardous flight condition, said device comprising:
-
an input for receiving sensor data; a plurality of hazard detecting functions, each of said functions coupled to receive a given set of said sensor data, for determining if a hazard condition exists; an alert generation device, having an input coupled to each of said plurality of hazard detecting functions, for evaluating an input signal indicative of the hazardous condition, and for outputting an alert signal based upon a predetermined alert schedule; and a command generating device for generating command indications based on the outputted alert signal. - View Dependent Claims (35)
