OR Two Inertial Reference Systems (IRS) in conjunction with one Flight Management Computer connected to either two Hybrid Multi-purpose Control Display Units (HMCDU) or two Multi-purpose Control Display Units (MCDU), meet the Inertial Navigation System requirements of FAA Advisory Circular 25-4 as the sole means of navigation for flights of up to 18 hours duration. A normal 10-minute ground alignment of the IRS has been demonstrated to be satisfactory between 70.2 degrees North and 70.2 degrees South latitudes. An extended 17-minute ground alignment is required between 70.2 degrees and 78.25 degrees North and South latitudes. In the NAV (navigation) mode the IRS will provide valid magnetic heading and track between 73 degrees North and 60 degrees South latitudes.* Insure IRS alignment is complete and all IRUs are in the NAV mode before the airplane is moved. When an IRU is in the ATT (Attitude) mode magnetic heading will drift after initialization in a manner similar to a directional gyro and requires crew monitoring and periodic manual updates to ensure adequate accuracy. * When Boeing Service Bulletin 767-34-0206, 767-34-0555 or production equivalent is incorporated, the northern boundary is extended to 82 degrees north latitude, except from 80 degrees west to 130 degrees west longitude the boundary is restricted to 70 degrees north latitude. The southern boundary is extended to 82 degrees south latitude, except from 120 degrees east to 160 degrees east longitude the boundary is restricted to 60 degrees south latitude. FAA APPROVED 04-03-08 D6T11321 Code 0001 Section 3.1 Page 13 BOEING AIRPLANE FLIGHT MANUAL NORMAL PROCEDURES F L I G H T (F M C S) M A N A G E M E N T C O M P U T E R S Y S T E M AIRPLANES WITHOUT FANS 1 FMC INSTALLED The Flight Management Computer System meets the requirements of AC 90-45A for an area navigation system when operated with radio updating. When operated in this configuration, the FMCS may be used for enroute and terminal area operations and RNAV approaches with the MAP display of the EHSI. In addition, the FMCS may be used in conjunction with the MAP display as a supplement to primary navigation means when conducting other types of approaches. The FMCS will provide navigation, guidance, and map display between 87 degrees North and 87 degrees South latitudes. The FMCS may be used for vertical navigation (VNAV) for enroute and terminal area operation. VNAV operations must be predicated on use of the primary altimeter system for altitude determination. When conducting RNAV approaches not obtained from the navigation data base, the navaid associated with the approach should be manually tuned and monitored to verify RNAV waypoint passage with RDMI radial and DME information. AIRPLANES WITH FANS 1 FMC INSTALLED The following FMCS demonstrations do not constitute operational approval. The Flight Management Computer System (FMCS) meets the requirements of FAA Advisory Circular (AC) 25-15 for long range navigation with the following equipment operational at dispatch: One Flight Management computer (FMC); two Hybrid Multipurpose Control Display Units (HMCDUs) or Multipurpose Control Display Units (MCDU); and two Inertial Reference Units (IRU) in NAV mode. To meet the requirements for RNAV operations (FAA AC 20-130A, JAA AMJ 20X2) the following equipment must be operational at dispatch (unless other appropriate procedures are used): One FMC, one CDU, one VHF Omni-directional Radio (VOR), one IRU in NAV mode, and either one Distance Measuring Equipment (DME) or Global Positioning System (GPS) (if installed). The FMCS has been shown to meet the requirements of AC 20-130A for a multi-sensor area navigation system when operated with radio or Global Position System (GPS) updating. When operated in this configuration, the FMCS may be used for enroute, terminal area operations and instrument approach navigation (excluding ILS, LOC, LOC-BC, LDA, SDF, and MLS approach procedures). The FMCS may be used to fly a RNAV approach procedure that overlays an ILS, LOC, LOC-BC, LDA, SDF, or MLS approach procedure when the localizer facility is inoperative subject to appropriate operational considerations, procedures, constraints, and authorizations. The FMCS will provide navigation, guidance, and map display between 87 degrees North and 87 degrees South latitude.

C O M P U T E R S Y S T E M AIRPLANES WITH FANS 1 FMC INSTALLED (Con’t.) The FMCS has been shown to meet the requirements of AC 20-129 for vertical navigation (VNAV) for enroute, terminal area operations, and instrument approaches (excluding ILS G/S approach procedures). The FMCS may be used to fly a VNAV approach procedure that overlays an ILS glideslope approach procedure when the glideslope facility is inoperative subject to appropriate operational considerations, procedures, constraints, and authorizations. GPS updating must be disabled for approach operations when operating outside the United States National Airspace, if the FMC database and charts are not referenced to WGS-84 reference datum, unless other appropriate procedures are used. When using the FMCS without GPS updating to conduct a terminal area procedure or an instrument approach, active DME/DME or VOR/DME updating as appropriate for the procedure being flown should be checked to ensure correct navigation. For an instrument approach, this check should be done no later than the final approach fix. As an alternative, it is acceptable to check for correct navigation using VOR or DME data relative to a map. For flight operations without Required Navigation Performance (RNP), the FMCS has been shown to meet the requirements of AC 20-130A for a multisensor area navigation system when operated with radio or Global Positioning System (GPS) updating. When operated in this configuration, the FMCS may be used for enroute, terminal area operations, and instrument approach navigation (excluding ILS, LOC, LOC-BC, LDA, SDF, and MLS approach procedures). The FMCS may be used to fly a RNAV approach procedure that overlays an ILS, LOC, LOC-BC, LDA, SDF, or MLS approach procedure when the localizer facility is inoperative subject to appropriate operational considerations, procedures, constraints, and authorizations.

C O M P U T E R S Y S T E M REQUIRED NAVIGATIONAL PERFORMANCE (RNP) OPERATIONS For RNP operations, the demonstrated RNP capabilities are as follows: Demonstrated RNP Flight Capability Versus Mode Of Flight Mode of Flight * FMC GPS Operational FMC GPS Not Operational LNAV with Autopilot Engaged 0.15 NM 0.13 NM* 0.28 NM LNAV with Flight Director 0.28 NM 0.14 NM* 0.41 NM 0.28 NM* Manual Control with MAP display only 0.52 NM 0.81 NM* 1.16 NM Applicable upon installation of Boeing Service Bulletin 767-34-0566 or production equivalent. The demonstrated RNP capabilities are predicated upon the assumptions, definitions, requirements and analysis in Boeing Document D926T0120-1, "757/767 FMCS RNP Navigation Capabilities, Generation 1," revision new or later FAA approved version. When using the MAP on the ND for manual flight for RNP operations of 2.00 nm or less down to the minimum demonstrated RNP, using a MAP scale of 10 nm or less has been shown to assure acceptable path track performance. RNP flight operations are subject to GPS satellite availability and/or navaid coverage for the selected route. The FMCS has been shown to meet the primary means RNP navigation with the following equipment operational at dispatch: two FMCs; two CDUs, HMCDUs, or MCDUs; two IRUs in NAV mode; and two sensors capable of complying with the RNP.
