Posted by John McHalePARSIPPANY, N.J., and ROME, Italy, 1 Dec. 2010. DRS Technologies and Alenia Aeronautica, both Finmeccanica companies, announced the joint development of a portable maintenance unit specially designed for the C-27J multipurpose cargo aircraft, for testing of onboard aircraft systems, loading of aircraft software, supporting ground maintenance, and training activities.Alenia Aeronautica selected the ARMOR X10gx rugged tablet PC to provide portable maintenance support unit on the aircraft. DRS customized the ARMOR to reduce the use of external components thereby increasing the integrated system's capabilities for use on the Alenia Aeronautica C-27J cargo aircraft. The portable maintenance unit (PMU), used for several applications, is capable of capturing and displaying technical documentation, providing interactive training for users, displaying aircraft's three-dimensional models, carrying out ground analyses of flight data, searching for damages, loading onboard software, and recording electrical and digital measurements in hostile operational conditions.The PMU is similar in size to an 8.5 by 11 inch sheet of paper and weighs approximately 4.5 pounds with a sunlight readable display. Certified to MIL-STD-810G and IP67, the unit is rugged and capable of surviving drops and vibration, extreme hot and cold temperatures and high humidity, and is fully sealed providing protection from the intrusion of water and sand.Alenia Aeronautica is already offering the ARMOR X10gx PMU on some C-27J airplanes for logistics support, in replacement of the previous Portable Maintenance Aid system which was heavier and provided less capability in the form of its interface and reporting function, DRS officials say.
