A rare engineering doctoral dissertation, not listed in OCLC.

Maximum payload range remains less than maximum range. When an aircraft is operated on a route that may exceed its maximum payload range capability, environmental conditions can vary the payload capability by as much as 20%. Current forecasting approaches, using monthly average performance, often result in sellable seats remaining empty. Trip fuel requirements are nearly exclusively predictable by the average wind component for a given route. This study discusses a forecasting model which models average wind components through a sinusoidal function, reflecting the annual repetitiveness of weather patterns. Long term changes in weather patterns were also considered. Monte Carlo simulation was used to model the variance around the mean predicted by the sinusoidal function, as well as to model expected payload demand. The resulting forecasting model thus combines supply with demand, allowing the risk of demand exceeding supply to be assessed on a daily basis.
