The Revamped ‘Ekran’

As part of import substitution programmes, the introduction of new technologies and a modern component base, specialists at 558 ARP JSC are refining and modernising flight data monitoring and recording equipment. A key focus has been the upgrade of the ‘Ekran’ aircraft crew warning system. It performs a vital function by continuously monitoring the status of on-board systems during flight and promptly alerting the pilot to faults, hazardous equipment operating modes, or critical flight parameters.

The company’s specialists have migrated the ‘Ekran’ system to a new hardware platform. In addition, a circuit board (part of the read-only memory unit) containing information in Russian, English and French has been developed, manufactured and successfully tested. Text messages are displayed on a dedicated indicator panel and cockpit display in the language selected by the pilot, warning of abnormal situations. The language can be switched instantly, making the system versatile and eliminating the need for bespoke development for each specific region.

The system is currently in successful operational use across several countries on Su-27, Su-30 and MiG-29 aircraft.
