higher. In addition, the aircraft must 
remain within the ETOPS authorized 
diversion time from an Adequate Air-
port that has RFFS equivalent to that 
specified by ICAO Category 7, or high-
er. 

(b) If the equipment and personnel re-

quired 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 as-
sets. A 30-minute response time for 
augmentation is adequate if the local 
assets can be notified while the divert-
ing airplane is en route. The aug-
menting equipment and personnel must 
be available on arrival of the diverting 
airplane and must remain as long as 
the diverting airplane needs RFFS.
