IFD-Series Touch-Screen Aviation GPS Navigators

As the heart of your ADS-B system, Avidyne’s IFD Series features the most intuitive Flight Management System in an easy-to-use, yet powerful design.

The Easy Choice

Avidyne’s IFD Series of touch screen navigators represent the next generation in flight management systems. Each provides 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 direct replacements for legacy systems, the IFDs 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.

Direct Replacements

The IFDs are direct replacements for popular Garmin GNS Series Navigators. In most cases, the IFDs can utilize the existing tray and connectors, and are compatible with all the popular interface configurations, which can greatly minimize installation costs.

Hybrid Touch: Knobs & Buttons or Touch-Screen

The award-winning Page & Tab user interface eliminates nested menus, allowing 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 IFDs Hybrid Touch capability allows pilots to perform virtually all of those same functions via the touch screen interface. Additionally, the IFDs offer MultiTouch functionalities such as pinch-zoom, map panning, and graphical flight plan editing. This can be done with the MultiTouch screen, or knobs and buttons depending on the pilot’s phase of flight.

Made by Pilots for Pilots

Avidyne’s full line of IFDs were designed for ease-of-use, especially during single-pilot IFR operations. As avid and enthusiastic pilots, the people at Avidyne understand the importance of workload reduction and simplicity of operation.

Navigation at your fingertips

Get where you need to go. That’s why we fly. Avidyne wants you to keep your head up when flying with your family and loved ones. That’s the reason Avidyne designed their FMS to be as user-friendly as possible. Go where you need to go in two clicks or less.

Easy Flight Planning

Extensive testing and customer experience have proven that the IFD user interface reduces button pushes and knob twists required with previous navigators by 50%-75% or more. Dropdown menus are logically placed to provide easy data entry of airways, exit waypoints, destinations, and approach procedures. To make planning even easier, the IFDs can automatically create user-defined waypoints.

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.

FMS Preview also allows you to view each of the available approaches graphically prior to selection. Unlike previous generation navigators, the Avidyne IFDs allow you to quickly load any number of destination airports and multiple approaches into your flight plan.

Graphical flight planning capability allows for easy editing of your flight plan with the touch of the screen. The convenient ‘rubber banding’ feature allows you to stretch any leg in the flight plan to easily deviate for weather or to accommodate an amendment from ATC.

Working Well Together

The IFDs, when paired in any combination, leverage Avidyne’s Byteflight databus architecture for cross-communication. A Keyboard Convenience feature allows for data entry on a familiar 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.

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.

GeoFill™ intelligently predicts the next waypoint entry, not based on its order in the database, but on its proximity to your current location or the previous waypoint in your flight plan. The IFDs autofill the remaining characters in the entry based upon distance from the current position, avoiding the cumbersome need to go through “bad” choices to get to the desired entry—dramatically reduces the number of pilot actions. GeoFill can reduce data entry by as much as 75%, reducing head-down time, and ultimately increasing efficiency and safety.

Entering a Hold

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

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 Radios

Managing your radios is easy with the IFD550, 540, and 440. 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.

The IFD’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.

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 IFDs 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.

Easy Radio Tuning

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

Terrain Awareness & FLTA

All IFD systems offer 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.

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 or obstacles is imminent. 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.
