required to support their intended operational capability. Each equipage class shall
(242AR3.7) meet the required information broadcast and receiving capability at the
indicated range to support the capability indicated in Table 3.4.3.2a and Table 3.4.3.2b.
The rationale for the requirements in Table 3.4.3.2a is as follows. Column 1 of Table
3.4.3.2a combines the equipage classes (which are based on user operational interests)
from Table 3.1.1.3.2a with the required ranges given in Table 3.4.3.1a. Information
exchange requirements by application were taken from Table 2-7 to determine the
broadcast and receive data required for each equipage class (column 2 of Table 3.4.3.2a
and Table 3.4.3.2b). A correlation between the equipage class and the ability of that class
to support and perform that application was done next. (The determination of the
information exchange ability of an equipage class to support a specific application is
determined by the information transmitted by that equipage class, while the ability to
perform a specific application is determined by the ability of that equipage class to
receive and process the indicated information.)
