Note.— It is expected that this feature will become
even more important as traffic increases.
d) automated systems shall be capable of assigning codes
with reference to the category of a flight, i.e. transit codes
shall be assigned to international transit flights and
domestic codes to flights confined within the smaller area
of use reserved for such codes;
e) automated systems shall permit the addition of a sophisticated
capability of assigning codes with reference to the
routing or special code protection required for specific
AFI FASID
flights, especially when this will permit economies in the
number of codes required;
f) the code assignment logic of an automated system shall
not impose any restrictions on the free choice of any
specific additional codes if this is required to satisfy new
requirements; and
g) automated code assignment systems shall aim at
international cooperation. National solutions should be
considered only as interim ones.
