The higher and faster the aircraft is flying, the further away from the field the descent must be started. The weight of the aircraft also will affect the speed of descent. For example, it takes longer and further to descend a fast and heavy high altitude airliner than it does to descend a slow and light 2-seat private aviation aircraft. Descents can easily begin more than 100 miles (160 km) from the field. It must be ascertained in advance that that runway available is long enough to provide the incoming aircraft with enough roll out distance to come to a safe stop. Runways as short as 800 feet (245 m) long can be used for private aviation at smaller general aviation airports. Runways for larger passenger jets normally extend to about 18,000 feet (5,500 m) long.
