Dassault and Honeywell team on EASy open architecture

Design permits changes to existing system as developments take place.

Dassault changed flightdecks to the use of FPV and path-based flight director rather than the traditional fixed pitch symbol. SVS with EASy shows (Top) extended runway centerline lying on the SVS terrain and (Bot) instantaneous view of flight instruments and CAS messages. Notice that EASy II also includes runway markings and textured runway surface.

This kind of avionics will also provide a defined fuel savings with the new RNP arrival and departures. The soon-to-come 4D trajectory-based operations will require RNP and controller–pilot datalink com­munications (CPDLC), but the fuel and time savings will be enormous.

In fact EASY 2 includes Honey­well’s FMS V7.1 which supports circling approaches, multi RNAV ap­proaches per runway, Baro-VNAV correction and temperature compensation calculator.

EASy 2 will include a host of other equipment enhancements such as ADS-B Out and the Honeywell SmartRunway awareness and advisory system.

The new display improvements will also support XM graphical weather and paperless charts, and Future Air Navigation System (FANS 1A) for transoceanic flights.

More EASy 2

Back to FAA’s basic requirements for a cockpit, engine instruments, cautions and warnings are not required to be in the standard FAA’s version of the standard “T.”

In early glass cockpits and even most of today’s aircraft, engine instruments are on another display outside the pilot’s instant field of view. The EASy flightdeck philosophy departed from this tradition by putting engine instruments next to the attitude display indicator rather than in the center of the panel.

This one move eliminates the need for you to leave your flight instrument scan at a critical moment. With EASy 2 and SVS, the pilot’s display is the same, but now the instruments are overlaid transparently on the SVS terrain display.

This includes the placement of cautions and warnings and messages, now in the modern standard, in direct view of the pilot next to the ADI providing instant command of all situations. EASy also places a duplicate CAS box next to each ADI, same as before and within the instantaneous field of view.

Messages are also on the MDU in the center panel along with expanded data and synoptic display. The interesting point here is that this design turns out to be crucial in the NextGen airspace operation.

Datalink messages in both NextGen and Europe’s SESAR will include departure clearances, route changes, arrivals, etc, and a Das­sault pilot will see it in the normal field of view. EASy flightdecks are equipped with 2 well crafted cursor control devices (CCDs) located in the ped­estal for one-handed use.

The CCD has a track ball and a few buttons that provide for managing and changing any item on the pilot’s primary display unit (MDU). Point and click functions with the track ball underneath your hand work smooth­ly, and selection of items keeps you heads up, rather than nose down in the CDU.

Another way to transmit is using the Dassault EASy CCD, which has a push-to-talk button located within easy reach of your index finger. The CCD and push-to-talk button is convenient and can be used in a aircraft with a side stick (if you are lucky enough to have one).

Also, with some clever thought, the left and right-side cursor control symbols are different so there is no confusion in operation. In fact the EASy CCD interface with the flightdeck provided a modern computer interface to a modern flightdeck, reduced the number of discrete buttons and controls, and led to the elimination of the old-fashioned CDU.

Harmonized flightdeck

With the new flightdeck design, EASy also harmonized all aspects of HUD with head-down displays. Using a single design concept, specifically flying FPV on all displays, the pilot does not need to accommodate convention changes of fixed pitch reference and back again to FPV when going from the HUD to heads-down—it’s all the same.

Dassault flightdeck design now also includes integration of the HUDs and enhanced flight vision system (EFVS). EFVS and the integration of SVS into the HUD is a major point of international collaboration by Dassault engineering with US and European regulators.

Current international collaboration efforts are focused on new systems concepts for landing in 1000-ft RVR, and eventually near zero using EFVS and SVS combined into the HUD. EFVS systems now are installed on the Falcon 2000 and 900 family and are being installed on the 7X.

Some of the other important aeronautical firsts in the bizjet world for Dassault are the first corporate aircraft with EFIS, and the first with HUDS and CAT III capability. The baseline EASy flightdeck was introduced at the NBAA 2000 convention in New Orleans.

Three years later EASy was certified and placed into service first with the Falcon 900EX, and later the Falcon 2000­EX. Since then EASy has been made standard equipment on the Falcon 7X, 900DX and 2000DX. Now, synthetic vision will be offered as an option as part of EASy 2 to new and existing EASy operators in 2010 on the Falcon 900DX and 900EX.

It is scheduled to be available for the 7X, 2000LX and 2000­DX in 2011. As Dassault Falcon Pres & CEO John Rosanvallon notes, “When EASy was introduced, it was a revolutionary advancement in cockpit technology and a giant step forward for business aviation.”

He goes on to say, “And today EASy continues its development with the addition of synthetic vision that will move today’s most advanced flightdeck further ahead into the future.” In my opinion, this may have been a bit understated.

When you see the EASy with SVS, you think you are in a space ship, and so will your boss.
