Getting Started Getting Started This section explains how to get started using the MX20. Information in this section describes the controls, data card, display, and basic operation. After reading this section, go to the Detailed Operation section for expanded explanations for each feature. Functions The MX20 contains thirteen major separate functions for the display of information. The function names are shown as “smart” keys at the bottom of the display.
Getting Started · FIS - Flight Information Service (WSI InFlight) (See page 71) · LT - Lightning Strikes (See page 81) · CHART - Chart View (See page 86) · RADAR - Weather Radar (See page 100) · SYS - System Information (See page 105) The Message Log displays information from the MX20 or reported to the MX20 by its external sensors. A flashing MSG annunciator notifies you of a new message that should be viewed.
Getting Started Controls Power/Brightness Two variations of the Power/Brightness control exist, a rotary knob or a rocker switch. Both are described here. The power switch is located in the upper right corner of the MX20. Turn the power rotary knob clockwise past the detent to turn the power on. Turn the power knob fully counterclockwise to turn the power off. With the power knob pushed in, the brightness is set automatically according to ambient light by a photo sensor.
Getting Started one of the function “smart” keys at the bottom of the display, the function keys change to provide options to control the display related to the current function. Function Key In Out Pan Info FN Smart Function Option Keys Smart Key Labels Change the function keys back to the function list by pressing the FN key. Menu/Enter MENU ENTER 4 The MENU/ENTER key is located on the bottom right corner of the MX20.
Getting Started Line Selection The Line Selection keys are on the right side of the MX20. Press the MENU/ENTER key to see the options for the current function. Press the LINE SELECT key next to each option to scroll through the choices for each option. Some options support tri-state choices, such as in Map mode. When you select a tri-state option, the option label will change with each key press between completely filled, partially filled, and empty.
Getting Started Data Card The Map database and other information is stored on a data card. The use of a data card allows you to easily update information. Only change the data card when the power is turned off. Handle your data card carefully. Do not touch the connector edge of the data card. To eject the card, use a soft blunt object to press the data card ejector. Gently pull the card straight out of the slot. Insert a data card by pushing the card straight into the slot.
Getting Started Display The MX20 display provides text and graphic information to give a “picture” of your flight and surroundings. The display brightness may be set manually or allowed to automatically adjust to ambient light conditions. At the bottom of the display, labels above the function keys change to show the different choices for each function to allow access to commonly used actions. A typical Custom Map function display is shown below. See page 112 for details on display care.
Getting Started Annunciations Advisory flags, data flags, and messages appear on the display to give information about the status of the MX20 or to provide operating information. Advisory Flags Annunciations will appear on the upper left side of the display to provide advisories for Traffic, Terrain, and Lightning. Advisory information is monitored and displayed regardless of the selected function.
Getting Started Data Flags Data flags appear on the left side of the display to notify you when there is a loss of reported information. The data usually displayed, such as lightning or nearby terrain, may still exist, but may not be displayed for technical reasons. For instance, when the amber TRAF data flag appears it means that the MX20 is not receiving Traffic information from the sensor. So, traffic may exist in your vicinity, but will not be displayed on the MX20.
Getting Started TCAD No valid traffic information is being received from the optional Ryan TCAD sensor. Traffic information will not be displayed. RDR (Amber) Indicates that radar status information is not available from the optional external radar transmitter head. Radar related functionality may not be available. RDR (Green) Indicates that the radar is ON and transmitting RF energy. Appropriate precautions should be taken.

This feature allows any Function with a pending advisory to quickly be recognized in the Function menu.
Getting Started Returning To Normal Condition After evaluating the advisory, to return to normal viewing simply select the original Function that was being viewed before the advisory was viewed. When this is done, the zoom level will be set back to 5 nm and the display mode will be returned to ARC mode. Alert Hot Key Traffic alerts go one step further than the Advisory hot key feature and will automatically bring up the Function Menu showing the Traffic function. This is called the “prompt” mode.
Getting Started Thumbnail Feature The Thumbnail feature provides a small map depiction that is overlaid in the upper left corner of the MX20 display. It provides for enhanced traffic and terrain situational awareness when not specifically viewing traffic or terrain related functions. For example, both traffic and terrain situational awareness can be maintained while viewing the Flight Plan Function. The Thumbnail is shown in both a small and large format, depending on the function currently being viewed.
Getting Started Obstructions on the Thumbnail Only “Red” obstructions within the 5 nm range are presented on the Thumbnail. This correlates directly to obstructions that are rendered in red on the other functions. Thumbnail Activation The Thumbnail incorporates logic that will either show or hide the thumbnail from view. It will only be shown when there is data to be presented and will be removed if not.

Detailed Operation Chart View (CHART) Function (Optional) The optional MX20 Chart View feature provides the capability to view Jeppesen Sanderson Inc. electronic charts. Two basic types of charts can be viewed: Approach charts and airport surface charts. Approach charts can be manually loaded and overlaid on the moving map during flight, while airport surface charts are automatically overlaid while on the ground. Both types of charts are also viewable from the Chart View Function in a chart manual fashion.
Detailed Operation relative to the chart data, using the standard map controls. · When viewed under the Chart View Function, more selection options are available for locating a specific chart among the charts in the database, and the chart is displayed similar to a standard chart manual (north up) with no position overlay. · A given approach chart must be “loaded” for map overlay usage by first selecting the airport of interest, then selecting the individual chart for that airport.
Detailed Operation Jeppesen. Currently not all charts and airport surface charts are geo-referenced. When a chart is viewed and a red “X” is present on the earth symbol (to the left of the chart name), the chart is NOT geo-referenced and thus cannot be “loaded.” Chart Overlay in the Custom/IFR Map On the Custom Map or the IFR En Route Map, approach charts (not airport surface charts) must be manually “loaded” as there are multiple approach charts that can apply for a given region (i.e.
Detailed Operation Selecting the Airport Pressing the LOAD CHART key on the Custom or IFR Map menu will present a list of airports that have geo-referenced approach charts available. The first airport within the list is the final destination waypoint as selected on the external GPS navigator, with additional airports listed based on nearest to present position search. Airports and approach charts that are not geo-referenced will not be shown for selection on this menu.
Detailed Operation Note The pilot must be aware that not all charts in the loaded database can be used as an overlay. Once the approach chart is loaded, a green Annunciator will illuminate at the top of the screen indicating the airport name and specific chart that has been loaded. Overlay Chart Loading Example 1. Press FN and then MAP or IFR. 2. Press MENU and then the LOAD CHART Line Select key. 3. Highlight the desired airport with the arrow “smart” keys and then press the SELECT “smart” key. 4.
Detailed Operation 5. Adjust the zoom level using the IN or OUT “smart” keys. Viewing the Chart as an Overlay Display of Coverage Area Once the desired approach chart has been loaded, a green Annunciator bar with the approach name is illuminated at the top of the Custom and IFR maps. If the aircraft is outside the coverage area of the approach chart, a black rectangular box will be presented that shows the coverage of the chart itself.
Detailed Operation screen at all times. The displayed zoom scale can be determined from the range rings on the arc and 360 displays, or from the distance to the displayed destination waypoint. When an approach chart is loaded and being displayed, the auto zoom mode will limit the low-end zoom level to 5 nm as the current waypoint is being approached. This prevents the display from zooming into a level where the overall situational awareness relative to the approach as a whole is lost.
Detailed Operation Chart View Function The Chart View Function is accessed by pressing the FN Function key and selecting the Chart View (CHART) function. The Chart View Function incorporates five menu items that control two basic operations: · Selecting a chart (for static viewing) · Loading a chart (for map overlay) The term “Selecting a chart” is used to designate that a given chart is selected for static viewing on the screen.
Detailed Operation Chart View Example: 1. Press FN and then CHART. 2. Depending on Chart status last used: Press MENU and then the SELECT AIRPORT Line Select key; or Highlight the desired airport with the arrow “smart” keys and then press the SELECT “smart” key. 3. Highlight the desired chart with the arrow “smart” keys and then press the LOAD or VIEW “smart” key. 4. View the chart. Adjust the zoom level using the IN or OUT “smart” keys.
Detailed Operation Select Airport The Select Airport operation allows the airport of interest to be selected from a pop-up list. The airports presented in the list are determined based on the final destination waypoint as the first entry, and a nearest type search for the remaining entries. This method allows the airport to be quickly located based on the current flight plan on the external GPS navigator.
Detailed Operation Airport Surface Charts Airport surface charts provide a graphical presentation of the airport surface area (runways, taxiways, buildings, towers and other objects), within the immediate airport vicinity.
Detailed Operation interest, the list of charts will have an “Airport” entry as the first item in the list. As with standard approach charts, when viewed from the Chart View Function, the aircraft’s ownship position is not shown on the airport surface chart. If an approach chart is currently loaded and being displayed (aircraft is in the air), it will take priority over displaying the airport surface chart.
Detailed Operation phase without having to manually un-load the approach and adjust the zoom scale. The transition logic is based solely on aircraft ground speed. When an approach chart is loaded and being flown, and the aircraft ground speed drops below the air/ground threshold (set from within the SYS Function), it is assumed that a landing has been performed.
Detailed Operation Typical Operational Scenario The following scenarios makes the assumption that: · The appropriate geo-referenced · The default ground zoom level is set to 0.5nm · The default air zoom level is set to “AUTO” charts are available and Typical Taxi Scenario On power up and GPS position acquisition, the Custom Map Function will show the aircraft on the surface chart at a zoom level of 0.5nm. The aircraft will be shown relative to taxiways and runways throughout the taxi procedure.
Detailed Operation Radar (RADAR) Function The MX20 I/O Radar product supports an interface for the Allied Signal/Bendix-King ART2000/2100 and RS-181A weather radars. The ART2000 weather radar is seamlessly integrated with the other functionality of the MX20 with a “RADAR” option available from the main function menu. Note that auto-tilt is not supported for the ART2000/2100. The ART2100 must be configured to emulate the ART2000. As a result, only the ART2000 functions are available with the ART2100.
