By Staff Writer | March 3, 2015

HAI Heli-Expo 2015 Orlando Fla. – DAC International, a Greenwich AeroGroup company, announced today that it recently completed vibration testing of its popular GDC64 iPad Tablet Interface Unit with Sikorsky Aircraft Corporation.

The GDC64 iPad Tablet Interface Unit transfers information from Sikorsky’s S-92 helicopter to the Flight Calculator Application iPad Function. Sikorsky announced at the 2014 Helicopter Association International’s Heli-Expo show that it had launched the company’s first iPad flight application for Sikorsky’s commercial S-92helicopter platform. Known as iFly Sikorsky, the application replicates common performance calculations described in the S-92 Rotorcraft Flight Manual.

In addition to performance calculations, iFly Sikorsky also has a configuration and weight and balance calculator utility. When initializing the application, an operator’s user credentials are validated. Sikorsky360 is a proprietary online support capability with more than 4,000 registered users worldwide.


DAC worked with Sikorsky Aircraft to test the GDC64 to the requirements of DO-160G section 8 Category U Curve G2 to meet the rigorous demands of the helicopter market.

“We performed the tests per the DO-160G specification and it passed with no issues or anomalies,” said DAC International’s Vice President of Manufacturing and Engineering Rick Horne.

The vibration tests were conducted in Texas at the Professional Test (EMI) Inc., Round Rock, test facility.
