Dynon's EFIS-D100 is the most affordable large screen Electronic Flight Information System on the market today. Based on the best-selling EFIS-D10A, the 7" wide-screen display features large, easy to read text and graphics and is capable of displaying multiple pages side by side in a split-screen format. The instrument integrates multiple flight instruments, including airspeed, altitude, gyro-stabilized magnetic compass, turn rate, slip/skid ball, bank angle, and vertical speed. Other useful functions include a clock/timer, g-meter, voltmeter and density altitude/true airspeed calculator.

High Resolution Screen
The EFIS-D100 features a 7” diagonal, color LCD which boasts the highest resolution in its class. The stunning display enables split-screen viewing to augment the primary EFIS data with other pages of information called up by the pilot. Six buttons arranged along the bottom of the screen serve as the interface to the softkey-driven menu system for easy access to in-flight functions and setting pilot preferences.

Advanced ADAHRS
Dynon's advanced ADAHRS (Air Data, Attitude and Heading Reference System) integrates over a dozen solid-state sensors that deliver exceptional performance and reliability. With the exception of the remote compass, the ADAHRS is built inside the EFIS-D100 instrument housing, saving installation time and space. Each ADAHRS undergoes a rigorous calibration regime at the factory to ensure accuracy over its full operating range. Unlike mechanical gyros, Dynon's rugged design is tolerant to aggressive flight maneuvers, automatically corrects itself anytime its gyros' capabilities are exceeded, and cannot be damaged by aerobatics or unusual attitudes.

Reliable Operation
Dynon's EFIS-D100 utilizes an embedded, multi-processor design that delivers real-time performance and stability. This purpose-built design is unencumbered by burdensome operating systems that typically slow down performance and require long boot times. Dynon's software design enables complete control to maximize execution speed and deliver robust reliability. A hallmark of the EFIS-D100's performance and a great safety feature is its ability to display the correct attitude within a few seconds of being powered on while in flight.

Safety Features
A unique safety feature available from Dynon is its optional AOA/Pitot that combines Angle-of Attack (AOA) and airspeed sensing into a single pitot design. The AOA capability assists pilots on approaches and generates an alert signal for audible annunciation whenever nearing stall conditions. This pitot is available in heated and non-heated versions.To guard against a power failure scenario, the EFIS-D100 may be optionally equipped with a Li-Ion Backup Battery. When power loss is detected, the instrument will automatically notify the pilot and immediately begin running on battery power for a minimum of 1.5 hours, enabling a safe landing.

The EFIS-D100 is equipped with a PC serial interface which provides the capability of uploading up to 25 user-defined lists for use as checklists, aviation data or other information that pilots wish to keep handy. The PC interface additionally facilitates downloading lifetime free firmware updates from Dynon's website. Cockpits equipped with more than one type of Dynon instrument can benefit from the connection capability that comes via the Dynon Smart Avionics Bus (DSAB). When linked via DSAB, pages displayed on one instrument may be shared for display on other Dynon instruments. DSAB not only allows you to share the fun with your co-pilot but delivers Dynon generated data directly to the instrument in front of you whenever you call upon it.

Dynon is developing a series of expansion modules that will add new capabilities and functionality to its existing line of EFIS, EMS and FlightDEK avionics. These optional modules provide exceptional value and performance while preserving the affordability of Dynon’s existing equipment. This modular concept promotes greater flexibility when configuring new aircraft panel systems and facilitates future expansion if so desired. Each expansion module is network connected to its line of avionics via the Dynon Smart Avionics Bus (DSAB). This two wire connection not only simplifies wiring but can extend individual module benefits to multiple interconnected Dynon instruments.

We just installed this in a 1968 Cessna 182. Awesome, the owner loves it. He also has a friend flys F-18s in the Marine Corp and flys this 182. He has told me numerous times that Dynon has all the information that the F-18 has!
