The Avidyne IFD540 FMS/GPS/NAV/COMs combines the best Flight Management System available, with a multi-channel digital VHF radio, in an easy-to-use, plug & play design.
The Easy Choice
The IFD540 represents the next generation in FMS/GPS/ NAV/COM systems. Providing 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
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. 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
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’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.
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.
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.
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.
The IFD540 & IFD440 offer three types of Terrain Awareness and Alerting capability: TA, FLTA and RTC.
Terrain Awareness (TA) is included on all IFD540 and IFD440 systems. TA warnings are displayed as red and yellow hashed-patterns over the standard color-contoured terrain base map. TA compares your current GPS altitude with the altitude of nearby terrain in the IFD’s database, and presents the color-coded TA patterns on the display over any terrain within a 10nm radius around the aircraft that is up to 1,000 feet below as a yellow hashed pattern and from 100 feet below to anything above as a red hashed pattern. No aural alerts are provided with TA.
Forward Looking Terrain Alerting (FLTA) is an actual TAWS-type functionality that is included on all IFD540s and as an option on the IFD440. FLTA projects the aircraft’s flight track in time to determine whether a collision with terrain is imminent. FLTA provides a solid yellow or red ‘flashlight’ beam projected on the map, along with an associated aural warning to alert the pilot of imminent impact with terrain or obstacle, using the same algorithms as higher-cost TAWS-B systems.
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.
Required Terrain Clearance (RTC) is also a TAWS-type functionality that is provided on all IFD540s and is optional on the IFD440. RTC alerts occur when the aircraft flight path is not projected to impact the terrain but the projected clearance between the aircraft flight path and nearby terrain or obstacles falls below a designated safe vertical distance. RTC provides a solid yellow and red ‘flashlight’ beam projected on the map, along with an associated aural warning. RTC alert distances vary based on phase of flight between 300’-1000’ using the same algorithms as higher-cost certified TAWS-B systems.
RTC alerts appear as solid red and yellow “flashlight beam” projections when the aircraft is within 60 seconds (yellow) and 30 seconds (red) of penetrating designated terrain clearance zones, along with a corresponding CAS message and aural alert.
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.
The IDF540 & IFD440 feature integrated Bluetooth® and WiFi support capability. This will allow for remote connectivity to tablet and keyboard devices that will make data transfer and display of information even easier.*.
* Bluetooth activated in R10.1. WiFi activation available in future software release.
