Section 139.315 Aircraft rescue and firefighting: Index determination.
(a) An index is required by paragraph
(c) of this section for each certificate
holder. The Index is determined by a
combination of - 
(1) The length of air carrier aircraft
and
(2) Average daily departures of air
carrier aircraft.
(b) For the purpose of Index determination, air carrier aircraft lengths
are grouped as follows:
(1) Index A includes aircraft less than
90 feet in length.
(2) Index B includes aircraft at least
90 feet but less than 126 feet in length.
(3) Index C includes aircraft at least
126 feet but less than 159 feet in length.
(4) Index D includes aircraft at least
159 feet but less than 200 feet in length.
(5) Index E includes aircraft at least
200 feet in length.
(c) Except as provided in Section 139.319(c),
if there are five or more average daily
departures of air carrier aircraft in a
single Index group serving that airport,
the longest aircraft with an average of
five or more daily departures determines the Index required for the airport. When there are fewer than five
average daily departures of the longest
air carrier aircraft serving the airport,
the Index required for the airport will
be the next lower Index group than the
Index group prescribed for the longest
aircraft.
(d) The minimum designated index
shall be Index A.
(e) A holder of a Class III Airport Operating Certificate may comply with
this section by providing a level of
safety comparable to Index A that is
approved by the Administrator. Such
alternate compliance must be described in the ACM and must include:
(1) Pre-arranged firefighting and
emergency medical response procedures, including agreements with responding services.
(2) Means for alerting firefighting
and emergency medical response personnel.
(3) Type of rescue and firefighting
equipment to be provided.

(4) Training of responding firefighting and emergency medical personnel on airport familiarization and
communications.

chemical, halon 1211, or clean agent; or
(2) 450 pounds of potassium-based dry
chemical and water with a commensurate quantity of AFFF to total 100 gallons for simultaneous dry chemical and
AFFF application.
(b) Index B. Either of the following:
(1) One vehicle carrying at least 500
pounds of sodium-based dry chemical,
halon 1211, or clean agent and 1,500 gallons of water and the commensurate
quantity of AFFF for foam production.
(2) Two vehicles - 
(i) One vehicle carrying the extinguishing agents as specified in paragraphs (a)(1) or (a)(2) of this section;
and
(ii) One vehicle carrying an amount
of water and the commensurate quantity of AFFF so the total quantity of
water for foam production carried by
both vehicles is at least 1,500 gallons.
(c) Index C. Either of the following:
(1) Three vehicles - 
(i) One vehicle carrying the extinguishing agents as specified in paragraph (a)(1) or (a)(2) of this section; and
(ii) Two vehicles carrying an amount
of water and the commensurate quantity of AFFF so the total quantity of
water for foam production carried by
all three vehicles is at least 3,000 gallons.
(2) Two vehicles - 
(i) One vehicle carrying the extinguishing agents as specified in paragraph (b)(1) of this section; and
(ii) One vehicle carrying water and
the commensurate quantity of AFFF
so the total quantity of water for foam
