First Claim
Patent Images
1. A method for recommending whether a pilot should land an aircraft, the method comprising:
- acquiring by a processor current weather data from a flight management system, the weather data selected from at least one of the group consisting of outside temperature, pressure, cloud conditions, angle, wind shear, turbulence, storms, precipitation information, ice and snow condition, runway surface coefficient, and standing water on the runway;
comparing by the processor evaluated current weather data to a threshold; and
providing a risk assessment to the pilot of landing the aircraft in consideration of the weather conditions and the comparison of the current weather data to the threshold.

Abstract
A system and method are provided for advising a pilot if it is safe to continue an approach to landing in adverse weather conditions. The system considers flight parameters from the flight management system, stored runway situational parameters, and weather information. The weather information may include, for example, reports, forecasts, and data collected in real time. The advice may be display as one of a plurality of recommendations based on a comparison of the weather information to a threshold.

9. A method for recommending whether a pilot should land an aircraft, the method comprising:
-
acquiring current weather data and flight parameters from the flight management system, the weather data selected from at least one of the group consisting of outside temperature, pressure, cloud conditions, angle, wind shear, turbulence, storms, precipitation information, ice and snow condition, runway surface coefficient, and standing water on the runway; determining by a processor if current weather data exceeds a threshold for a landing to proceed in consideration of the flight parameters; alerting the pilot that a landing is recommended in view of the weather data not exceeding the threshold; determining landing parameters from the combination of the flight management system and weather reference model sources under adverse weather; selecting one of a plurality of graded recommendations for landing by the processor based on the weather data, flight parameters, and landing parameters; and providing the selected graded recommendation to the pilot. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A system for recommending whether a pilot should land an aircraft, comprising:
-
circuitry configured to receive weather data; a flight management system configured to monitor flight parameters; an inferencing engine comprising; a flight phase based inhibitor configured to allow the inferencing engine to proceed only when the aircraft is in a landing phase; an evidence handler configured to continuously seek for unsafe weather conditions; a correlator configured to seek connection between different weather parameters across multiple weather sources and formulate a pattern of continuously deteriorating weather conditions and formulate an evolving pattern, the weather parameters selected from at least one of the group consisting of outside temperature, pressure, cloud conditions, angle, wind shear, turbulence, storms, precipitation information, ice and snow condition, runway surface coefficient, and standing water on the runway; a hypothesis handler configured to form and evaluate a plurality of hypothesis based on the analyzed weather parameters and related flight parameters, and form a predictive trend for a safe landing evaluation based on the aircraft and different scenarios; a temporal filter configured to remove weather data demonstrating chattering or intermittency; and a landing impact decider configured to generate an advisory message indicating whether the pilot should proceed with a landing; a weather based landing advisory reference model configured to define a model considering a landing site, an airframe, and flight parameters; a learning loop configured to update the weather based landing advisory reference model based on previous landings on challenging weather conditions, previous flight conditions, and previous weather data; and a display configured to display the advisory message. - View Dependent Claims (18)
