1fa. Winter Storms and Air TravelWinter weather can play havoc with air travel in the United States. Naturally, some years are worse than others, and the winter of 2010–2011 was especially difficult. Between November and early February, snow and ice conditions associated with four major storms caused U.S. airlines to cancel some 86,000 flights, with thousands of other flights encountering major delays. These events amounted to a significant portion of all scheduled flights for an industry recovering from some economic difficulties, In December 2010, 3,7 percent of all U.S. flights were cancelled because of winter storms, in contrast to the 2.9 percent cancelled the previous December. Even airports not normally subject to crippling winter storms, such as Hartsfield-Jackson Atlanta International Airport, were subject to the cancellation of thousands of flights when a single January storm left behind 6 inches of snow in a city that usually receives half that much in an entire season (Figure 1–1–1).One of the problems associated with winter storms is that aircraft loaded to capacity with passengers can be forced to wait on taxiways between terminal gates and runways for extended periods. For example, the time aircraft must wait before being de-iced contributes to delays An outcry of consumer criticism led to a policy taking effect in April 2010 that allows the U.S. Department of Transportation to levy fines for air carriers of up to $27,500 per passenger when flights are forced to remain on the tarmac for more than three hours. Some believe this will motivate airlines to cancel flights more readily than in the past, causing greater inconvenience for passengers forced to wait hours or even days for another flight to get them to their destination On the other hand, passengers are now much less likely to spend half a day on a crowded aircraft just waiting to get to the runway.Often the disruption of air travel is due to what happens outside the airport during winter weather. Sometimes it is easier for airlines to fly crews in from other areas than it is to wait for scheduled personnel who are delayed by impassable highways on their way to the airport. And of course, flights scheduled to depart San Diego on a warm, sunny day may be unable to do so because the aircraft needed for the flight is stranded at an East Coast airport.Weather in other seasons also poses different hazards to commercial aviation, as will be discussed in later chapters of this bookFIGURE 1-1-1 Snowbound Airplanes in Atlanta, January 2011....In the depths of winter, what are the approximate chances of your plane being grounded because of weather in the United States?
