                     TITLE 14--AERONAUTICS AND SPACE
 
CHAPTER I--FEDERAL AVIATION ADMINISTRATION, DEPARTMENT OF TRANSPORTATION 
                               (CONTINUED)
 
PART 121_OPERATING REQUIREMENTS: DOMESTIC, FLAG, AND SUPPLEMENTAL OPERATIONS--
 
   Subpart F_Approval of Areas and Routes for Supplemental Operations
 
Sec. 121.122  Communications facilities--supplemental operations.

    (a) Each certificate holder conducting supplemental operations other 
than all-cargo operations in an airplane with more than two engines must 
show that a two-way radio communication system or other means of 
communication approved by the FAA is available. It must ensure reliable 
and rapid communications under normal operating conditions over the 
entire route (either direct or via approved point-to-point circuits) 
between each airplane and the certificate holder, and between each 
airplane and the appropriate air traffic services, except as specified 
in Sec. 121.351(c).
    (b) Except as provided in paragraph (d) of this section, each 
certificate holder conducting supplemental operations other than all-
cargo operations in an airplane with more than two engines must provide 
voice communications for ETOPS where voice communication facilities are 
available. In determining whether facilities are available, the 
certificate holder must consider potential routes and altitudes needed 
for diversion to ETOPS Alternate Airports. Where facilities are not 
available or are of such poor quality that voice communication is not 
possible, another communication system must be substituted.
    (c) Except as provided in paragraph (d) of this section, for ETOPS 
beyond 180 minutes each certificate holder conducting supplemental 
operations other than all-cargo operations in an airplane with more than 
two engines must have a second communication system in addition to that 
required by paragraph (b) of this section. That system must be able to 
provide immediate satellite-based voice communications of landline 
telephone-fidelity. The system must provide communication capabilities 
between the flight crew and air traffic services and the flight crew and 
the certificate holder. In determining whether such communications are 
available, the certificate holder must consider potential routes and 
altitudes needed for diversion to ETOPS Alternate Airports. Where 
immediate, satellite-based voice communications are not available, or 
are of such poor quality that voice communication is not possible, 
another communication system must be substituted.
    (d) Operators of turbine engine powered airplanes do not need to 
meet the requirements of paragraphs (b) and (c) of this section until 
February 15, 2008.
