11/3/11 8900.1 CHG 184MNPS criteria. A particular operator can (under most circumstances) be authorized(without recertification under the current edition of AC 120-33, Operational Approval ofAirborne Long-Range Navigation Systems for Flight within the North Atlantic MinimumNavigation Performance Specifications Airspace) to conduct Canadian MNPS operations withthose aircraft and navigation system combinations authorized for that operator in NAT/MNPSairspace. However, due to the unique nature of operations in high latitudes and in areas ofmagnetic unreliability (AMU), approval for Canadian MNPS operation is not automatic. Eachproposed operation must be evaluated on its own merits. OpSpec B059 is available for issuanceto 14 CFR part 135 certificate holders or part 91 subpart K (part 91K) program managers only.OpSpec B039 would be issued for NAT/MNPS in the part 135 database of the WebOPSS.OpSpec B039 is available in the 14 CFR parts 121 and 125 databases of the WebOPSS, as thepolicy for authorization for these certificate holders may be conducted and approvedconcurrently.B. Special Factors. The following special factors must be considered and carefullyevaluated before granting air navigation approvals for operation in Canadian MNPS airspace.1) The following directions apply for operators currently authorized to use anaircraft in NAT/MNPS airspace:a) A primary means inertial navigation system (INS)/inertial reference system(IRS)/Inertial Reference Unit (IRU) meeting NAT/MNPS criteria automatically meets CanadianMNPS criteria.b) Other LRNS meeting NAT/MNPS criteria automatically meet CanadianMNPS criteria except for operations in the AMUs. The LRNS must be evaluated on acase-by-case basis for AMU authorization.c) Operations at high latitude airports (greater than 67° N/S) must not beauthorized unless INS platform alignment has been successfully demonstrated and approved forthose latitudes. If operations are proposed for areas in the Canadian MNPS that fall within theAMU, a validation flight and AMU authorization is required. One of the FAA NextGen oceanicspecialists must be consulted.2) Training programs and crew procedures for operations at high latitudes mustprovide techniques and methods for the following:• Approaches and departures using appropriate heading references other thanmagnetic; and• Use of ground-based Navigational Aids (NAVAID) oriented to appropriatedirectional references other than magnetic.3) The following directions apply for operators who are not currently authorized touse an aircraft and a navigation system combination in NAT/MNPS airspace, but propose tooperate in the Canadian MNPS airspace.6UNCONTROLLED COPY WHEN DOWNLOADEDCheck with FSIMS to verify current version before using
