The integrated flight information system (IFIS) is a multi-function display (MFD) upgrade that adds electronic charts (e-charts), graphical weather (GWX), and enhanced map (e-map) features to the existing electronic flight instrumentation system (EFIS).

The IFIS is made up of one or two (optional) file server units (FSU), two cursor control panels (CCP), and two MFDs (with ethernet capability). A third VHF COM transceiver with datalink and a radio interface unit (RIU) with an integral communication management unit (CMU) are required when the optional Universal weather (GWX-5000) is installed. An XM weather receiver is required when the optional XM weather (GWX-3000) is installed.

The primary system component is the FSU. The CCPs are part of the EFIS, and allow a dedicated interface to the MFD for controlling the IFIS functions via on-screen menus. The VHF datalink radio and RIU provide air and ground data communications with compatible air-ground networks when the optional universal weather is installed. A control display unit (CDU) requests universal weather from the ground-based service provider and displays IFIS messages. The optional XM weather receiver receives a constant broadcast of graphical and textual weather data from the XM satellite radio weather service provider. The XM satellite provides weather data to the FSU through the XM weather antenna and the XM weather receiver.

---

The FSU supplies stored graphical symbology to the MFDs through a dedicated bi-directional ethernet bus. The FSU contains large data bases using non-volatile random access memory (NVRAM). In a dual FSU installation, each FSU is connected to the respective on-side MFD only. A second optional FSU is available for installation. 

The key operating features for the FSU are as follows:

• E-charts available for display on the MFD
• Automated e-chart selection linked with FMS flight plan
• GWX available for display on the MFD (for example: plan map)
• E-map (geographical/political, airways, airspace) available for display on the FMS PPOS map and FMS plan map
• System status pages are available for display on the MFD

The FSU also provides a gateway service for upload and download of data to other LRUs on the aircraft using Rockwell Collins portable access software (CPAS-3000). A data base subscription or data service is required for each of the features of IFIS. There are data bases associated with each of the IFIS features that require periodic updates. The FSU contains the following data bases with the update cycle:

• Charts (14 day update cycle)
• Airspace (28 day update cycle)
• Airways (28 day update cycle)
• Political (update on user demand)
• Geographical (update on user demand)
• Graphical weather (XM and UV) (update on user demand)

When an installed data base is out of date, the CHECK DATABASE STATUS message shows on the MFD. The DATABASE EFFECTIVITY pages shows the flight crew or maintenance personnel the status of the installed data base.

Electronic Charts

The electronics charts (ECH-5000) function provides the display of arrival procedure (STAR), approach procedure, airport diagram, departure procedure (SID or DP), noise and notice-to-airmen (NOTAM) charts on the MFD. Access to the e-charts format is through CCP CHART pushbutton. With the FMS installed, the origin, departure, and alternate airports and procedures are automatically filled in from the flight plan data to provide easy access to all charts pertinent to the flight plan. Pilot entered stations IDS are also supported. The e-chart function also depicts the aircraft position on all geo-referenced charts.

Chart files are updated (on a subscription basis with Jeppesen) on a periodic basis. The chart database is dataloaded into the FSU.

Split Charts

The split chart function provides the display of two charts. The split chart view provides a profile and minimum strip views. In the split chart view while in flight, when the TOGA pushbutton is pushed, the view defaults to the briefing strip view. The DSK DATA control knob on the CCP controls the display for the split charts.

Automatic Charts

The automatic charts function provides an automatic chart display on the MFD. When the aircraft is in an on ground status, the chart of the destination airport is shown on the display.

Enhanced Map Overlay (Post SB 350-46-004)

The enhanced map overlay (OVL-5000) function provides the display of individual symbology of geopolitical boundaries (state and country boundaries, major water), airways (high and low), and restricted airspace on the MFD present position and plan maps.

The enhanced map overlays provide the functions that follow:

• NEXRAD (from GWX-300X or GWX-5000)
• Airways (Victor and Jet)
• Airspace (class B and class C terminal airspace and restricted airspace)
• TFRs (from the GWX-300X)

Universal Graphical Weather (Post SB 350-46-003)

Universal weather (GWX-5000) is requested for uplink through the CDU. The graphical weather images are uplinked to the aircraft through the VHF No. 3 (option) system. The graphical weather images are displayed on the MFD. The MFD format displays one stored graphical weather at a given time. The images received are stored in the FSU and are automatically listed in the graphical weather image menu. The graphical weather menu provides effectivity information and timestamp information of the various images and forecast products. Images that are no longer valid are automatically deleted from the FSU when the aircraft is on the ground.

The universal weather images are provided as follows:

• NEXRAD radar images (CONUS)
• Tops and movement (CONUS)
• Weather depiction (ceiling and visibility summary) (Worldwide)
• Icing (at forecast times) (Worldwide)
• Turbulence (at altitudes) (at forecast times) (Worldwide)

Note: 
Only one service, either XM weather or universal weather, may be installed on an FSU at one time.

In a dual FSU installation, the uplinked images are cross-talked between the units to avoid the cost of requesting the images on both sides.

Radio Interface Unit

The radio interface unit (RIU) is required for installations that include the universal weather (GWX-5000). Graphical weather images are requested from the ground station through control pages on the CDU. The requested GWX images are uplinked through the VHF COM No. 3 (option) unit and supplied to the FSU through the RIU.
