Joint Operational Support Airlift Center

Joint Operational Support Airlift Center (JOSAC) is the airlift branch of United States Transportation Command (USTRANSCOM). JOSAC specializes in the airlift of senior defense officials within the continental United States. JOSAC schedules aircraft from all four services – Air Force, Army, Marine Corps, and Navy – to meet airlift requests from DoD officials.

JOSAC is located at Scott Air Force Base in Illinois, about 20 miles from St. Louis, Missouri. JOSAC was stood up in July 1996 to efficently schedule to Operational Support Airlift assets of the Air Force, Navy, Marines and Army. Presently there are 80 units in the USA that provide aircraft for JOSAC to schedule; this yields a fleet of 130 aircraft assigned to those flying units, but only 20 of them are open for scheduling use. Aircraft utilized include the C-21A, C-12, C-26, UC-35, C-20, C-40, and C-9.

Schedulers receive requests from travel validators via the JALIS database (Joint Air Logistics System), which is an Oracle-based system developed by the US Navy. JOSAC's office is split into two major areas: "The Floor" (Day Schedulers) and "Execution Cell" (Same Day Flight Following). The Floor is further divided into three scheduling teams: Team 1 schedules requests for Saturday, Sunday, Monday,Team 2 schedules requests for Tuesday and Wednesday, Team 3 schedules Thursday, and Friday. Requests to JOSAC are prioritized by a PUJC Code of Pri 1, Pri 2, or Pri 3. DoD four-Star generals are mandatory users of the OSA fleet and will get first priority along with any Priority 2 request.

The average weekday has about 35 airlift requests. Several requests are put on the same aircraft for scheduling efficiency. Airlift requests for only one or two non-dv, non-Pri 2 are rarely scheduled. JOSAC is manned by Civil Service personnel and Military personnel from the Army, Navy, and Marines. The Current Director of JOSAC is Colonel Douglas Pavek (USA).
