uAvionix Developing Satellite ADS-B
uAvionix is working on a wingtip ADS-B Out device that will work with satellite-based ADS-B systems that will be used in several countries and the U.S. system, which relies on ground stations. The skyBeacon X will pack upward and downward pointing antennas into a compact integrated device that will also replace a wingtip position light. The development project was spurred by contact from Canadian pilots who could be required to install ADS-B Out as early as 2023. Nav Canada, the not-for-profit corporation that supplies air traffic services in Canada, will use the Aireon satellite system for ADS-B surveillance and that requires antennas pointed skyward. Most ADS-B systems now available for GA aircraft are designed for the U.S. terrestrial system and the few that do offer the so-called “antenna diversity” required in Canada are significantly more expensive. uAvionix hopes to have the system ready for sale in 2021.
Engine Problems Suspend Hemisphere
Textron has suspended development of its flagship Hemisphere business jet, largely because of delays in development of Safran’s Silvercrest engine. As it suspended the program, Textron also cancelled its contract with Safran for the trouble-plagued engine. The Silvercrest has no active orders now. The engine was announced in 2006 and was supposed to be ready by 2011 but persistent problems with airflow dynamics have delayed its entry into service. Safran redesigned the high pressure compressor to address the issues and is continuing development and testing the engine.
