Probabilistic Analysis of Aircraft Fuel Consumption Using Ensemble Weather Forecasts
نویسندگان
چکیده
The effects of wind uncertainty on aircraft fuel consumption are analyzed using a probabilistic trajectory predictor. The case of cruise flight subject to an average constant wind is considered. The average wind is modeled as a random variable; the wind uncertainty is obtained from ensemble weather forecasts. The probabilistic trajectory predictor is based on the Probability Transformation Method, which is a method that evolves the wind probability density function; the output of the probabilistic trajectory predictor is the probability density function of the fuel consumption. A general analysis is performed for arbitrary winds distributed uniformly, with a twofold objective: 1) present the capabilities of the probabilistic trajectory predictor, and 2) understand how the wind uncertainty affects the fuel consumption.

Consensus Probabilistic Forecasting
To make optimal decisions, end-users of decision support systems require information accurately describing the uncertainty of the underlying weather forecasts. Air temperature, dew point temperature, and wind speed are critical surface weather variables in many economic sectors. The generation of sharp and calibrated probabilistic forecasts and their effective presentation to decision makers ar...
متن کاملPerformance of Trajectory Models with Wind Uncertainty
Typical aircraft trajectory predictors use wind forecasts but do not account for the forecast uncertainty. A method for generating estimates of wind prediction uncertainty is described and its effect on aircraft trajectory prediction uncertainty is investigated. The procedure for estimating the wind prediction uncertainty relies uses a time-lagged ensemble of weather model forecasts from the ho...

Probabilistic forecasts of wind vectors are becoming critical as interest grows in wind as a clean and renewable source of energy, in addition to a wide range of other uses, from aviation to recreational boating. Unlike other common forecasting problems, which deal with univariate quantities, statistical approaches to wind vector forecasting must be based on bivariate distributions. The prevail...

Probabilistic forecasts of wind speed are becoming critical as interest grows in wind as a clean and renewable source of energy, in addition to a wide range of other uses, from aviation to recreational boating. Statistical approaches to wind forecasting offer two particular challenges: the distribution of wind speeds is highly skewed, and wind observations are reported to the nearest whole knot...
متن کاملA new method for robust route optimization in ensemble weather forecasts
This paper presents a new dynamic programming method for multi-objective route optimization of ships. The method, which is an extension of the known Dijkstra's algorithm, uses the concept of Pareto e ciency to handle multi-objective optimization and can be used with both deterministic and ensemble weather forecasts. The advantage of the presented method in combination with deterministic weather...
