IFD540 & IFD440


IFD540 & IFD440 Aviation GPS

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.

Avidyne IFD540 and IFD440

The Easy Choice

The IFD540 & IFD440 represent the next generation in Aviation GPS 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

Our 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

Removing GNS530 for IFD540

The IFD540 & IFD440 are direct 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. In addition, Avidyne offers the GPS-only IFD410 and IFD510, which are plug & play replacements for the GNS400 and GNS500 respectively See for yourself!

Flight 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.

Graphical Flight Plan Editing

Aviyne IFD540 rubberbanding

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. GeoFill can reduce data entry by as much as 75%, dramatically reducing head-down time.

Avidyne GeoFill

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 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

Avidyne FMS Preview

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

Avidyne FMS Preview

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.

With v10.2 software, the IFD540/440 also supports orbit-around-a-point holding patterns.

“Next Leg” Depiction

IFD540 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.



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. You can also simultaneously tune both the active and standby frequencies, both of which can be easily monitored when coupled with Avidyne’s AMX240 Audio Panel.

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.

IFD540 Easy Radio Tuning

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.

IFD540 Multiple Frequencies

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

Avidyne IFD Fuel Range Ring

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

Avidyne IFD Charts

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 & FLTA

All IFD540/440 systems offer passive Terrain Awareness capability 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.

For an even greater measure of safety, Forward Looking Terrain Alerting (FLTA) actively projects the aircraft’s flight track in time to determine whether a collision with terrain is imminent. (FLTA is optional on IFD440)

Avidyne IFD Terrain Awareness

TA warnings are shown as red and yellow hashed- patterns. FLTA provides a solid red or yellow “flashlight beam” projection of potential impact point, with 60 seconds (yellow) and 30 seconds (red) Terrain Alert warnings, along with a corresponding CAS message and aural alert.

Integrated WiFi & Bluetooth® Connectivity

The IFD540 and IFD440 offer integrated Bluetooth and WiFi capability (included with IFD540, optional on IFD440). This allows for wireless connectivity to tablets, keyboards, and other mobile devices and custom applications that make data transfer and display of information even easier.
