<br />within ARC D-II is "100 percent oflarge
<br />airplanes at 60 percent useful load".
<br />The performance requirements of the
<br />cri tical aircraft can further refine the
<br />runway length requirements. However,
<br />stage length requirements for typical
<br />business jet aircraft, up to ARC D-II,
<br />are considered to be the ultimate
<br />determining factor for runway length.
<br />The average maximum range of 2,846
<br />nm has been calculated from five of the
<br />most popular business jet aircraft,
<br />including the Canadair 601, Cessna Jet
<br />(Jl), Gulfstream IV, Learjet 45, and
<br />Hawker 125-800XP. From this a typical
<br />stage length of 1,000 miles has beeF.!.
<br />used to calculate the runway length
<br />requirement. As shown in the table, the
<br />FAA recommends a runway length of
<br />
<br />6,000 feet to serve this category of
<br />aircraft with a median stage length
<br />value of 1,000 miles. Runway 8-26 is
<br />currently the only runway at HYI
<br />providing at least 6,000 feet.
<br />
<br />Analysis specific to individual business
<br />jet aircraft has been completed to
<br />determine if the length of primary
<br />Runway 12-30 would be adequate for
<br />the range of business jets currently or
<br />forecast to operate at HYI. Table 3C
<br />presents this analysis. These business
<br />jets could typically be expected to stage,
<br />or refuel, at cities within a 1,000 mile
<br />radius of San Marcos, enabling aircraft
<br />to reach cities such as Denver, Phoenix,
<br />Tampa, and Miami.

<br />As indicated in the table, a range of
<br />runway lengths is required by business
<br />jet aircraft. Aircraft such as the Lear
<br />55 requires 7,300 feet for take-off at 95
<br />
<br />degrees. Other aircraft which operate
<br />at HYI, such as the G-IV require at
<br />least 7,000 feet.
