proach speeds. AC 150/5325-4B stipulates that runway length determination for business jets consider
a grouping of airplanes with similar operating characteristics. The AC provides two separate “family
groupings of airplanes,” each based upon their representative percentage of aircraft in the national
fleet. The first grouping is those business jets that make up 75 percent of the national fleet, and the
second group is those making up 100 percent of the national fleet. Table 3E presents a partial list of
common aircraft in each aircraft grouping. A third group considers business jets weighing more than
60,000 pounds. Runway length determination for these aircraft must be based on the performance
characteristics of the individual aircraft.

Table 3F presents the results of the runway length analysis for business jets developed following the
guidance provided in AC 150/5325-4B. To accommodate 75 percent of the business jet fleet at 60 per-
cent useful load, a runway length of 5,200 feet is recommended. This length is derived from a raw
length of 4,900 feet that is adjusted, as recommended, for runway gradient and consideration of land-
ing length needs on a contaminated runway (wet and slippery). To accommodate 100 percent of the
business jet fleet at 60 percent useful load, a runway length of 6,300 feet is recommended.
Utilization of the 90 percent category for runway length determination is generally not considered by
the FAA unless there is a demonstrated need at an airport. This could be documented activity by a
cargo carrier or by a business jet operator that flies out frequently with heavy loads. To accommodate
75 percent of the business jet fleet at 90 percent useful load, a runway length of 7,700 feet is recom-
mended. To accommodate 100 percent of business jets at 90 percent useful load, a runway length of
9,800 feet is recommended.
Another method to determine runway length requirements for business jet aircraft at Arlington Munic-
ipal Airport is to examine aircraft flight planning manuals under conditions specific to the airport. Sev-
eral business jet aircraft were analyzed for takeoff length required with a design temperature of 96.6
degrees F at a field elevation of 628 feet MSL.
