remain within the ETOPS authorized
diversion time from an Adequate Airport that has RFFS equivalent to that
specified by ICAO Category 7, or higher.
(b) If the equipment and personnel required in paragraph (a) of this section
are not immediately available at an
airport, the certificate holder may still
list the airport on the dispatch or
flight release if the airport-s RFFS can
be augmented to meet paragraph (a) of
this section from local fire fighting assets. A 30-minute response time for
augmentation is adequate if the local
assets can be notified while the diverting airplane is en route. The augmenting equipment and personnel must
be available on arrival of the diverting

the diverting airplane needs RFFS.

airspace if the certificate holder conducting supplemental operations shows
the route is safe for operations and the
Administrator finds that traffic density is such that an adequate level of
safety can be assured. The certificate
holder may not use such a route unless
it is approved by the Administrator
and is listed in the certificate holder-s
operations specifications.

(2) Minimum en route altitudes.
(3) Ground and airborne navigation
aids.
(4) Air traffic density.
(5) ATC procedures.
(b) Any route widths of other routes
determined by the Administrator are
specified in the certificate holder-s operations specifications.
