4 NATIONAL & STATE OVERVIEW OF AIR MEDICAL COVERAGE IN 2011
Figure 1 is a map of the United States showing main and satellite base locations of all the Rotor Wing and
Fixed Wing Air Medical Services in the US in 2011. The gold stars indicate main office locations and the orange
circles indicate 10 minute fly circles around each base where a RW is stationed 1 . The size of the 10 minute fly
circle varies with the cruise speed of the particular RW make and model resident at that base. The white blocks
show bases (airports) where Fixed Wing aircraft are based. Summary statistics on numbers of services, bases and
aircraft are provided at the bottom of the figure.

Table 1 lists the number of air medical services headquartered in each state as well as the number of out-ofstate
services with bases in that state. This is followed by the number of bases with RW, the number with FW and the
total number of bases in the state. Note that if a single air medical service has a base with both RW and FW, the base is
included in the RW base inventory and in the FW base inventory, but included once in the total base inventory. For
this reason, the sum of ‘Bases with RW’ and ‘Bases with FW’ may or may not equal ‘Total Bases’ in the state.
In addition to an inventory of bases, Table 1 also includes data on the number of RW and FW aircraft in each
state. To place all these figures in context, state populations and geographic area are provided for reference. National
totals for each category are provided at the bottom of the table.
Figures 2 and 3 are bar charts which graphically display the information in Table 1. Finally, Table 2 lists the
number of each type of service (RW only, RW/FW, FW only) headquartered in each state.
1 Note that a 10-minute fly circle actually translates into a ~20 minute response time since 7 to 12 minutes are usually required for initial preflight
and launch.
