Pie chart. 1  Comparing pie charts of different sizes could be misleading as people cannot accurately read the comparative area of circles. 2  The usage of thin slices, which are hard to discern, may be difficult to interpret. 3  The usage of percentages as labels on a pie chart can be misleading when the sample size is small.
Hill Air Force Base. Hill Air Force Base (IATA: HIF, ICAO: KHIF, FAA LID: HIF) is a major U.S. Air Force base located in northern Utah, just south of the city of Ogden, and near the towns of Clearfield, Riverdale, Roy, Sunset, and Layton. It is about 30 miles (48 km) north of Salt Lake City.
It was closed by the Air Force in 1969, and the base was given to Wendover City in 1977. Tooele County, Utah, assumed ownership of the airport and base buildings in 1998, and the County continues to operate the airfield as a public airport.
