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 IFD440 shares the same basic functionality in large and compact display formats.

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 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.


Made by Pilots for Pilots

The IFD440 was designed for ease of use, especially during single-pilot IFR operations. As avid and enthusiastic pilots, we at Avidyne understand the importance of workload reduction and simplicity of operation.

The IFD440 provide an easy page & tab user interface, plus advanced radio management including automated NAV frequency tuning and COM frequency nomination, automatic frequency identification, easy-to-modify graphical flight planning, and Avidyne’s exclusive GeoFill™ waypoint nomination.
