Based on Honeywell’s Primus Epic for Dassault EASy (Enhanced Avionics System)

3 Key Benefits of EASy IV Avionics

There are three key benefits of EASy IV Avionics:

Streamlined Aircraft Operations

With EASy IV, an advanced Interactive Navigation map (INAV) better depicts airspace restrictions and terrain resolution and combined with a new interactive Vertical Situation Display (VSD), gives a better picture of thunderstorm vertical development.  These features provide pilots with a better sense of where they are heading in three dimensions while decluttering the flight display, and allowing them to layer navigation, weather, and traffic information as desired.

The latest version of Honeywell’s NextGen FMS provides additional capabilities, such as new RNP AR approaches for improved access to runways affected by terrain or high-density traffic.  New graphic CPDLC features provide seamless data communications for different phases of flight, thereby reducing crew workload.  EASy IV offers broader compliance with various datalink standards including ATN-B1 (or CPDLC) for Europe.

By upgrading to EASy IV, Falcon 7X operators can add a valuable feature that is standard on the Falcon 8X, an enhanced Auto-Throttle (A/T) option.  In the event of an in-flight shut down, the EASy IV engine-out A/T is capable of managing power, allowing recovering automation for the two remaining engines and freeing pilots from this task.

New Jeppesen chart features are also integrated into EASy IV, including a night mode that keeps an even light level on the flight deck during night approaches.  Charts feature a new ‘Panoramic’ mode adding another valuable situational awareness cue.


Enhanced Situational Awareness

Additional new features greatly reduce the risk of runway incursion.  On the ground, 2D/3D Airport Moving Maps (AMM) give a sharp display of runways, taxiways, ramps, and other airport features, making ground navigation easier at crowded airports, especially in low visibility.  A new TCAS system includes ADS-B In and Out, so pilots will see traffic in the air and on the airport map.

Operators can also add SiriusXM® weather products with all the graphic and text weather data it provides.  These images are all of the U.S., Canada, and the Caribbean.


Improved Operational Safety Features

An improved Takeoff and Landing Data (TOLD) function allows additional inputs for more precise calculation of realistic landing distances.  This enables operators to meet new EASA and FAA mandates on Landing Distance at Time of Arrival (LDTA).

A new Runway Overrun and Alerting System (ROAAS) analyzes aircraft trajectory and TOLD performance to determine if the aircraft can come to a full stop within the remaining runway length.  Early PDF alerts improve pilot perception of runway end margin and safe approaches and go-arounds.


EASy History

Dassault introduced the original groundbreaking EASy (Enhances Avionics System) flight deck in 2002 on the Flacon 900EX, bringing a new level of situational awareness and flight planning ease to the business jet community.  EASy IV continues that tradition, offering more capability for pilots while meeting the new demands of advances air traffic management systems.
