August 19, 2014: New details have emerged throwing light on what the cockpit environment of the in-development HTT-40 basic trainer aircraft (BTA) will be like. HAL is pushing ahead with its HTT-40 propeller trainer effort, and has now declared a requirement for an Integrated Avionics Tester (IAT), a ground based test facility, designed & developed to carry out testing and integration of the avionics system functionalities of the HTT-40 platform. HAL needs the rig to verify and validate the performance in an integrated environment. According to details published by HAL, the HTT-40 avionics architecture consists of central 6”x 8” SMFD, 5” x 7” MFD, conventional GPS & communication controllers and standby instrument system in each cockpit for display. The SMFD is a smart display with integral on-board processor. The SMFD shall have direct interface with aircraft sensors such as engine, fuel, hydraulics, brake and electrical systems etc. The SMFDs perform the data processing, health monitoring, warning & logic function. The SMFDs perform the video generation for its own display as well as the MFDs in both the cockpits. The SMFDs in front cockpit and rear cockpit shall have data synchronization via Ethernet port.
