Section 1. GENERAL 1.1 Garmin 4XXW Series GPS/WAAS Nav Com The Garmin GNS Series GPS/WAAS Navigator is a panel-mounted product that contains a GPS/WAAS receiver for GPS approved primary navigation under TSO-C146a, (plus optional VHF Com and VHF Nav radios) in an integrated unit with a moving map and color display. The 4XXW Series unit features a graphical display which may also be used to depict traffic, weather, or terrain data.
1.2 GPS/SBAS TSO-C146a Class 3 Operation The GNS complies with AC 20-138A and has airworthiness approval for navigation using GPS and SBAS (within the coverage of a Satellite Based Augmentation System complying with ICAO Annex 10) for IFR en route, terminal area, and non-precision approach operations (including those approaches titled “GPS”, “or GPS”, and “RNAV (GPS)” approaches).
Applicable to dual installations consisting of two Garmin GNSS units: The Garmin GNSS navigation system has been found to comply with the requirements for GPS Class II oceanic and remote navigation (RNP-10) without time limitations in accordance with AC 20-138A and FAA Order 8400.12A. The Garmin GNSS navigation system can be used without reliance on other long-range navigation systems. This does not constitute an operational approval.
Section 2. LIMITATIONS 2.1 Pilot’s Guide The Quick Reference Guide, part number and revision listed below (or later applicable revisions), must be immediately available for the flight crew whenever navigation is predicated on the use of the 4XXW Series unit.
2.3 System Software This AFMS/AFM is applicable to the software versions shown in Table 1. The Main and GPS software versions are displayed on the start-up page immediately after power-on. Approved Software Version Software Item Main SW Version GPS SW Version Flight Stream 210 (or later FAA approved versions for this STC) SW version 5.20 5.0 2.11 As displayed on unit 5.20 5.0 2.11 (Displayed on GNS) Table 1 – Required Equipment 2.
2.5 Flight Planning For flight planning purposes, in areas where SBAS coverage is not available, the flight crew must check RAIM availability. Within the United States, RAIM availability can be determined using the Garmin WFDE Prediction program, Garmin part number 006-A0154-04 software version 3.00 or later approved version with Garmin approved antennas or the FAA’s enroute and terminal RAIM prediction website: www.raimprediction.net, or by contacting a Flight Service Station.
Both Garmin GPS navigation receivers must be operating and providing GPS navigation guidance for operations requiring RNP-4 performance. North Atlantic (NAT) Minimum Navigational Performance Specifications (MNPS) Airspace operations per AC 91-49 and AC 12033 require both GPS/SBAS receivers to be operating and receiving usable signals except for routes requiring only one Long Range Navigation sensor. Each display computes an independent navigation solution based on its internal GPS receiver.
accordance with the LNAV or LP approach procedure. When conducting instrument approaches referenced to true North, the NAV Angle on the AUX-Units/Position page must be set to True. The navigation equipment required to join and fly an instrument approach procedure is indicated by the title of the procedure and notes on the IAP chart.
The terrain display is intended to serve as a situational awareness tool only. By itself, it may not provide either the accuracy or the fidelity on which to base decisions and plan maneuvers to avoid terrain or obstacles. 2.9 VNAV – Vertical Navigation Calculation Page VNAV information accessible by pressing the “VNAV” button may be utilized for advisory information only.
This STC does not relieve the operator from complying with the requirements of 91.23 or any other operational regulation regarding portable electronic devices. AFMS, Garmin GNS 4XXW GPS/SBAS System FAA APPROVED 190-00356-03 Rev.
Section 3. EMERGENCY PROCEDURES 3.1 Emergency Procedures No change. 3.2 Abnormal Procedures 3.2.1 LOSS OF GPS/SBAS NAVIGATION DATA When the GPS/SBAS receiver is inoperative or GPS navigation information is not available or invalid, the GNS will enter one of two modes: Dead Reckoning mode (DR) or Loss Of Integrity mode (LOI). The mode is indicated on the GNS by an amber “DR” or “INTEG”.
LOSS OF INTEGRITY (LOI) MODE: Navigation ..................... FLY TOWARDS KNOWN VISUAL CONDITIONS NOTE All information derived from GPS will be removed. NOTE The airplane symbol is removed from all maps. The map will remain centered at the last known position. “No GPS Position” will be annunciated in the center of the map. 3.2.
Section 4. NORMAL PROCEDURES Refer to the 4XXW Series unit Quick Reference Guide defined in paragraph 2.1 on page 7 of this document for normal operating procedures. This includes all GPS operations, VHF COM and NAV, and Multi-Function Display information. For information on TIS traffic or data linked weather, see the Pilot’s Guide addendum for optional displays. For information on active traffic device or Stormscope operation and displays see the Pilot’s Guide addendum for display interfaces.
4.3 HSI and EHSI Operation If an HSI is used to display navigation data from the GNS the pilot should rotate the course pointer as prompted on the GNS. If an EHSI is used to display navigation data from the GNS the course pointer may autoslew to the correct course when using GPS navigation. When using VLOC navigation the course pointer will not autoslew and must be rotated to the correct course by the pilot.
4.5 Coupling the Autopilot during approaches CAUTION When the CDI source is changed on the GNS, autopilot mode may change. Confirm autopilot mode selection after CDI source change on the GNS. Refer to the FAA approved Flight Manual or Flight Manual Supplement for the autopilot. This installation prompts the flight crew and requires the pilot to enable the approach outputs just prior to engaging the autopilot in APR mode.
4.6 Traffic Mode Selection (Optional) If the GNS is interfaced to a traffic device, the GNS can be used to control the mode of the traffic system. This is accomplished by pressing the cursor knob while on the dedicated traffic page to enter/exit the traffic device menu. It is important to note that while the traffic device menu is active, the current state of the traffic system is not displayed. The state of the traffic device is only displayed once the traffic device menu is exited. Section 5.
Section 7. SYSTEM DESCRIPTIONS 7.1 Pilot’s Guide See Garmin 4XXW Series unit Pilot’s Guide for a complete description of the 4XXW Series unit. 7.2 Manual GTN Crossfill Manual GTN Crossfill is a feature that will keep the GNS system in sync with a flight plan that is being used on the GTN system. The GTN will not automatically keep its flight plan in sync with changes made on the GNS system. Manual crossfill feature is “one way” – from the GTN to the GNS.
7.3 Flight Stream 210 The Flight Stream 210 provides wireless communication of specific flight plan information and GPS sensor data to a PED (Personal Electronic Device) from the GNS. For details on the operation and features of the Flight Stream 210, please refer to the GNS 400W/500W Series Optional Displays, P/N 190-00356-30 Rev J.
