Paper Abstract

It has been apparent for more than a decade that the weather-forecast wind speed reaching flight crews in commercial aircraft differs by an average of +/- 15 knots from the wind speed actually experienced during the flight at cruise altitude. We recently analyzed wind-versus-altitude forecasts and found that the forecast altitude of maximum wind is also in error, by an average of +/- 4800 feet. In this era of increasing free-flight operations, we propose the use of airborne laser radar to measure winds above and below the aircraft in real time, so that a pilot can optimize the flight altitude with respect to prevailing winds. Analysis shows that such a lidar system would generate fuel savings of $LR100,000 to $LR200,000 per aircraft per year, especially for transoceanic routes. THis saving would pay for the instrument in one to two years.
