AC 120-42B 6/13/08b. The certificate holder’s plan for conducting operations within these areas must includethe following elements:(1) Requirements for Designating Alternates. Certificate holders should designate aset of alternate airports regardless of their distance from the planned route, such that one or morecan reasonably be expected to be available in a variety of weather conditions to support anecessary diversion. The flight must have sufficient fuel as required by § 121.646, if applicable,and should be able to make a safe landing and the airplane maneuvered off of the runway at theselected diversion airport. In the event of a disabled airplane following landing, the capability tomove the disabled airplane should exist at that airport, so as not to block the operation of anyrecovery airplane. In addition, those airports designated for use should be capable of protectingthe safety of all personnel by being able to:(a) Offload the passengers and crewmember in a safe manner during adverseweather conditions;(b) Provide for the physiological needs of the passengers and crewmembers for theduration of the stay at the diversion airport until safe evacuation; and(c) Safely extract passengers and crewmembers as soon as possible (execution andcompletion of the passenger recovery is expected as soon as possible within 48 hours followingdiversion).(2) Passenger Recovery Plan. Except for supplemental all-cargo operations, eachcertificate holder conducting operations in the polar areas must have a passenger recovery plan atdesignated diversion airports as discussed in paragraph (1) above and in Chapter 4,paragraph 403c(5). The passenger recovery plan in these Polar Regions should also includespecial consideration for the possibility of extreme cold weather, limited passenger facilities, andthe need to initiate passenger recovery without delay.(3) Fuel Freeze Strategy and Monitoring. The certificate holder must have a fuelfreezestrategy and procedures for monitoring fuel freezing. The certificate holder may wish todevelop a fuel freeze strategy and monitoring program (e.g., alternate fuel freeze pointtemperature determination based on actual measurements of uploaded fuel), in lieu of using thestandard minimum fuel freeze temperatures for specific types of fuel used. In such cases, thecertificate holder’s fuel freeze analysis and monitoring program for the airplane fuel load issubject to FAA approval. The certificate holder should have procedures established that requirecoordination between maintenance, dispatch, and assigned flight crewmembers to convey thedetermined fuel freeze temperature of the fuel load on board the airplane.(4) Communication Capability. The certificate holder must have effective voicecommunications and/or data link capability for all portions of the flight route. The requirementsof § 121.99 apply to all ETOPS operations in these areas. For all other operations, companycommunications may be accomplished using HF voice, HF data link, satellite communication(SATCOM) voice or SATCOM data link. Because of the limitations of VHF and satellite-basedvoice communications, ATC communications will probably require high frequency (HF) voiceover portions of these routes. The FAA recognizes that SATCOM may not be available for shortPage 48 Par 603
6/13/08 AC 120-42Bperiods during flight over the Poles. Communication capability with HF radios also may beaffected during periods of solar flare activity. The certificate holder should consider predictedsolar flare activity and its effect on communications for each flight that is dispatched foroperations into these areas.(5) MEL Considerations. The certificate holder must amend its MEL to reflect theitems that must be operational for these operations. For ETOPS flights, all MEL restrictions forthe applicable ETOPS operations apply. Before receiving FAA authority to conduct theseoperations, all certificate holders should review its MEL for consideration of the dispatchavailability of the following systems/equipment:(a) Fuel quantity indicating system (FQIS), including the fuel tank temperatureindicating system;(b) APU (when the APU is necessary for an airplane to comply with ETOPSrequirements), including electrical and pneumatic supply to its designed capability,(c) Autothrottle system;(d) Communication systems relied on by the flight crewmember to satisfy therequirement for communication capability; and(e) Except for all-cargo operations, an expanded medical kit to include automatedexternal defibrillators (AED).(6) Training. The certificate holder should address the following training requirementsin its approved training programs:(a) QFE/QNH and meter/feet conversions (required for flight crewmember anddispatcher training);(b) Training requirements for fuel freeze, to include maintenance, dispatch, andflight crewmember training (special curriculum segments);(c) General route-specific training on weather patterns;(d) Relevant airplane system limitations (for example fuel temperature limits);(e) Role of the maintenance department in providing airplane systems capabilityinformation to dispatch and flight crewmember to aid the PIC in diversion decision making;(f) Crewmember training in the use of the cold weather anti-exposure suit,(g) For dispatch and crewmember considerations during solar flare activity, thecertificate holder must be aware of the content of AC 120-52, Radiation Exposure of CertificateHolder Crewmembers, and provide crewmember training as stated in AC 120-61, CrewmemberTraining on In-Flight Radiation Exposure; andPar 603 Page 49
