Unique Installation Offers Both A Mission Display Capability And PFD For Left Cockpit Side

Universal Avionics (UA) is supplying dual EFI-890H Advanced Flight Displays and dual AHS-525 Attitude Heading Reference Systems (AHRS) for an AS365 Dauphin helicopter installation. The installation offers a unique way to have both a mission display capability and Primary Flight Display (PFD) for the left cockpit side.

The integration allows for a single EFI-890H Advanced Flight Display in each cockpit side; the right display is configured as a PFD and provides requirements for single pilot Instrument Flight Rules (IFR) functionality. The display on the left panel configures as a Mission Video or Navigation Display (ND), but also allows reversion to use as a second PFD. This provides the helicopter with expanded mission capabilities while providing a backup PFD capability for dual pilot operations. The displays use on-side sensors for primary attitude, heading, and air data instruments while providing comparators to detect sensor differences. The UA AHS-525 AHRS sensors deliver the attitude and heading sources, providing both digital and analog outputs needed by the helicopter systems.

“This is a new and innovative approach for display upgrades,” said Grady Dees, UA Director of Technical Sales. “The flexibility of the EFI-890H Advanced Flight Display is demonstrated with this unique application,” he added. “Having a mission display that can also function as a Navigation or PFD is attractive to many utility and special mission operators. Most displays that can provide mission video are not robust, certified products. This display brings the best of both worlds to the limited cockpit space available.”

As a default, the display in the left instrument panel powers-up as a ND with pilot (right PFD) selections for navigation sources. An external video switch allows the left display to present mission system video in full screen format. When needed, the left PFD controller Display Revert selection can be activated, allowing the left display to function as a PFD using left-side AHRS and Air Data Computer (ADC) sources. The Display Revert allows toggling this display from ND/Mission Video to PFD functions. When operated as a PFD, all left PFD selections are independent from the rightside PFD.
