Pt. 135, App. G

14 CFR Ch. I (1-1-19 Edition)

(3) All ETOPS Alternate Airports within
the authorized ETOPS maximum diversion
time are reviewed for any changes in conditions that have occurred since dispatch.
(b) In the event that an operator cannot
comply with paragraph G135.2.5(a)(1) of this
appendix for a specific airport, another
ETOPS Alternate Airport must be substituted within the maximum ETOPS diversion time that could be authorized for that
flight with weather conditions at or above
operating minima.
(c) Pilots must plan and conduct ETOPS
under instrument flight rules.
(d) Time-Limited Systems. (1) Except as provided in paragraph G135.2.5(d)(3) of this appendix, the time required to fly the distance
to each ETOPS Alternate Airport (at the allengines-operating cruise speed, corrected for
wind and temperature) may not exceed the
time specified in the Airplane Flight Manual
for the airplane-s most limiting fire suppression system time required by regulation for
any cargo or baggage compartments (if installed), minus 15 minutes.
(2) Except as provided in G135.2.5(d)(3) of
this appendix, the time required to fly the
distance to each ETOPS Alternate Airport
(at the approved one-engine-inoperative
cruise speed, corrected for wind and temperature) may not exceed the time specified
in the Airplane Flight Manual for the airplane-s most time limited system time
(other than the airplane-s most limiting fire
suppression system time required by regulation for any cargo or baggage compartments), minus 15 minutes.
(3) A certificate holder operating an airplane without the Airplane Flight Manual
information needed to comply with paragraphs G135.2.5(d)(1) and (d)(2) of this appendix, may continue ETOPS with that airplane
until February 17, 2015.
G135.2.6 Communications Requirements.
(a) No person may conduct an ETOPS
flight unless the following communications
equipment, appropriate to the route to be
flown, is installed and operational:
(1) Two independent communication transmitters, at least one of which allows voice
communication.
(2) Two independent communication receivers, at least one of which allows voice
communication.
(3) Two headsets, or one headset and one
speaker.
(b) In areas where voice communication facilities are not available, or are of such poor
quality that voice communication is not possible, communication using an alternative
system must be substituted.
G135.2.7 Fuel Requirements. No person may
dispatch or release for flight an ETOPS
flight unless, considering wind and other
weather conditions expected, it has the fuel
otherwise required by this part and enough

fuel to satisfy each of the following requirements:
(a) Fuel to fly to an ETOPS Alternate Airport.
(1) Fuel to account for rapid decompression
and engine failure. The airplane must carry
the greater of the following amounts of fuel:
(i) Fuel sufficient to fly to an ETOPS Alternate Airport assuming a rapid decompression at the most critical point followed by
descent to a safe altitude in compliance with
the oxygen supply requirements of Section 135.157;
(ii) Fuel sufficient to fly to an ETOPS Alternate Airport (at the one-engine-inoperative cruise speed under standard conditions
in still air) assuming a rapid decompression
and a simultaneous engine failure at the
most critical point followed by descent to a
safe altitude in compliance with the oxygen
requirements of Section 135.157; or
(iii) Fuel sufficient to fly to an ETOPS Alternate Airport (at the one-engine-inoperative cruise speed under standard conditions
in still air) assuming an engine failure at the
most critical point followed by descent to
the one engine inoperative cruise altitude.
(2) Fuel to account for errors in wind forecasting. In calculating the amount of fuel required by paragraph G135.2.7(a)(1) of this appendix, the certificate holder must increase
the actual forecast wind speed by 5% (resulting in an increase in headwind or a decrease
in tailwind) to account for any potential errors in wind forecasting. If a certificate holder is not using the actual forecast wind based
on a wind model accepted by the FAA, the
airplane must carry additional fuel equal to
5% of the fuel required by paragraph
G135.2.7(a) of this appendix, as reserve fuel to
allow for errors in wind data.
(3) Fuel to account for icing. In calculating
the amount of fuel required by paragraph
G135.2.7(a)(1) of this appendix, (after completing the wind calculation in G135.2.7(a)(2)
of this appendix), the certificate holder must
ensure that the airplane carries the greater
of the following amounts of fuel in anticipation of possible icing during the diversion:
(i) Fuel that would be burned as a result of
airframe icing during 10 percent of the time
icing is forecast (including the fuel used by
engine and wing anti-ice during this period).
(ii) Fuel that would be used for engine
anti-ice, and if appropriate wing anti-ice, for
the entire time during which icing is forecast.
(4) Fuel to account for engine deterioration. In calculating the amount of fuel required by paragraph G135.2.7(a)(1) of this appendix (after completing the wind calculation in paragraph G135.2.7(a)(2) of this appendix), the certificate holder must ensure the
airplane also carries fuel equal to 5% of the
fuel specified above, to account for deterioration in cruise fuel burn performance unless
the certificate holder has a program to monitor airplane in-service deterioration to
cruise fuel burn performance.
