IFD440 Touch Screen FMS/GPS/NAV/COM, by Avidyne

Avidyne's IFD540 & IFD440 FMS/GPS/NAV/COMs combine the best Flight Management System available, with a multi-channel digital VHF radio, in an easy-to-use, plug & play design.

IFD540 & IFD440 The Easy Choice

The IFD540 & IFD440 represent the next generation in FMS/GPS/ NAV/COM systems. Each provides VHF communication and SBAS/ LPV precision navigation and are designed to meet the accuracy and integrity requirements for ADS-B as part of the NextGen airspace initiative. As plug-and play replacements for legacy systems, the IFD540 & IFD440 each share the same basic functionality in large and compact display formats respectively. When it comes to panel-mounted avionics, you now have a choice and the choice is easy. Avidyne.

Hybrid Touch: Knobs & Buttons or Touch-Screen

The award-winning Page & Tab user interface allows you to go to any page in the system with only one or two clicks. In addition to the dedicated knobs and buttons that many pilots prefer for frequent pilot actions, the IFD540 & IFD440’s Hybrid Touch capability allows pilots to perform virtually all of those same functions via the touch-screen interface, as well as providing additional MultiTouch functionality like pinch-zoom, map panning, and graphical flight plan editing, allowing the pilot to decide to use the MultiTouch screen, or knobs and buttons depending on the pilot’s phase of flight. Avidyne’s unique Hybrid Touch user interface eliminates nested menus and allows pilots to view any page with only one or two clicks.

Plug & Play Replacements

The IFD540 & IFD440 are physical plug & play replacements for the Garmin GNS530 and GNS430 respectively, using the existing tray and connectors, and they are compatible with all the popular interface configurations, which can greatly minimize installation costs.

light Planning Has Never Been Easier

Entering an IFR flight plan is easier than ever with the IFD540 & IFD440. Extensive testing and customer experience have proven that the IFD540 & IFD440 user interface reduces button pushes and knob twists required with previous navigators by 50%-75% or more. Drop-down menus are logically placed to provide easy data entry of airways, exit waypoints, destinations, and approach procedures.

With the IFD540 & IFD440’s graphical flight planning capability, you can easily edit your flight plan with the touch of the screen. The ‘rubber banding’ feature allows you to stretch any leg in the flight plan to make a deviation for weather or to accommodate an amendment from ATC.

GeoFill™ Reduces Data Entry Time

GeoFill intelligently predicts the next leg or waypoint on your flight—not based on its order in the database, but on its proximity to your current location or the previous waypoint in your flight plan—eliminating the fumbling through irrelevant NAVAIDs common to other systems. Auto-filling the remaining characters in the entry—based upon distance from the current position and avoiding the cumbersome need to go through obviously “bad” choices (too far away) to get to the desired entry—dramatically reduces the number of pilot actions. In fact, there is a high probability that it will display your desired waypoint on the initial suggestion.

As an example, the logical GeoFill choice based upon the existing route is HNK rather than an irrelevant waypoint such as HM – Haneida NDB in Japan which an older system would have suggested because it is alphabetically ahead in the database.

FMS Preview

Avidyne’s exclusive FMS Preview™ is a powerful flight planning feature that makes it even more intuitive to load flight plans by showing you a real-time graphical depiction of each proposed modification in cyan prior to selection. FMS Preview makes it easy to visualize before selecting a desired waypoint, airway, hold or hold geometry, Direct-To, approach, approach transition and any other terminal procedures.

Easy Loading of Approaches

The dedicated PROC (Procedure) button allows you to quickly load approaches at your destination airport by selecting from the intuitive pop-up list on the map. FMS Preview allows you to view each of the available approaches graphically prior to selection. Unlike previous-generation navigators, the IFD540 & IFD440 allow you to quickly load any number of destination airports and multiple approaches into your flight plan.

Entering a Hold is Easy

You can easily enter and fly a Hold at any waypoint, including VORs, intersections, user-defined waypoints, airports, etc. The FMS will default to a standard hold pattern at current Heading, and all parameters are easily editable.

“Next Leg” Depiction

On the map, the current leg you are flying is always depicted as a solid magenta line. To give you a clear indication of your next leg, the IFD540 & IFD440 will display a magenta & white “candy cane” line, which is especially handy during entries into a holding pattern.

Quick Access to Info You Need

The IFDs feature a convenient Side Tab, so you can quickly view your Data page, Flightplan, or Nearest Airports while viewing the Map. While in FMS mode, you can access your MAP any time simply by clicking or dragging the side tab.


Managing your radios is easy with the IFD540 & IFD440. Frequencies can easily be entered either by rotating the dual knobs on the left, or by using the touch-screen numeric keypad. COM frequencies can also be tuned directly by touching the displayed frequencies on Info, Nearest, and Frequency List pages.

IFD540 & IFD440’s powerful FMS automatically nominates, auto-tunes, identifies, and monitors the NAV radio frequencies, so you may never have to tune another VOR or ILS frequency again! Should you choose to do so, manual tuning is easily completed with the pop-up numeric key pad or by simply typing the identifier for the VOR

Easy Radio Tuning

Touching any frequency in the Info list, Freq page, or Nearest page automatically transfers it into the Standby window.

Multiple Frequency Formats and Station Readout

Communications are greatly improved with the IFDs. You can configure your unit(s) to have multiple standby frequencies, decoded agency identifiers, and Rx/Tx Indicators.

The IFD540 & IFD440 decode the active and standby frequencies based on proximity in the database and display the names of the stations in plain English, providing a handy reminder of the agency to which you will be transmitting when pressing the push-to-talk button.

Low-Fuel Protection

When the IFD is connected to a compatible Fuel Totalizer System, the IFD will display a green Fuel Range Ring, indicating a fuel reserve of 45 minutes. A dashed green circle indicates a maximum range without reserve.

Electronic Approach Charts and Airport Diagrams

The IFD540 includes CMax™ Approach Charts & Airport Diagrams. Utilizing Jeppesen’s Jeppview® charts subscription services, CMax provides Worldwide approach charts and a database of over 6,000 airport diagrams, most of which are geo-referenced, allowing for the display of your ownship and flight plan position right on the chart or airport diagram.

Terrain Awareness

The IFD540 & IFD440 include Terrain Awareness which can be displayed over the color-contoured terrain base map for easy pilot recognition of an imminent encounter with nearby terrain. Caution Alerts are provided when a collision with terrain is projected within approximately 60 seconds, and Warning Alerts are provided for terrain projected within approximately 30 seconds. FLTA provides aural alert messaging as well. The Forward Looking Terrain Alerting (FLTA) capability provides a solid yellow or red impact point based on flight path projection.

Working Well Together

The IDF540 & IFD440, when paired in any combination, leverage Avidyne’s Entegra Release 9 Byteflight databus architecture. A Keyboard Convenience feature allows for data entry on a QWERTY keyboard that automatically appears when an alpha-numeric data field is highlighted, making data entry as familiar to you as your computer or smart phone. With GeoFill, the IFD540 & IFD440 will virtually always guess accurately your next waypoint after only entering one or two letters.

In dual installations, the dual-databus architecture allows pilots to enter the flightplan on the QWERTY keyboard of one unit, while viewing the Map on the other.

Made for Each Other

Built on a dual databus architecture, the IFD540 & IFD440 are key components in Avidyne’s new panel-mounted plug & play avionics suite, which also includes the AMX240 Audio Panel, AXP340 ADS-B Extended Squitter Mode S Transponder, and DFC90 Digital Autopilot.
