Mission-critical factors for life saving SAR operations include: maximum detection range of emergency beacon transmissions, flight time to locate the beacon(s), available time at the rescue site. These parameters are addressed by the Techest DF SAR. 121.5 MHz, 156.8 MHz, 243 MHz and 406 MHz are cyclically scanned providing 360 degrees DF bearing. The system is compact using a single radome antenna and a user-friendly cockpit indicator unit. Utilization of the 406 MHz COSPAS-SARSAT signal has the advantage of providing up to a 30 percent increase in detection range due to the higher output power of signal compared to the 121.5MHz homing signal. Use of the 406MHz signal also enables 406MHz message decoding and GPS coordinates of the target beacon if they are provided. The system gives a relative bearing straight-line approach vector for all intercepted beacon frequencies with an accuracy of 5 degrees. If ARINC 429 is available true bearing and range indications are possible. For more information visit www.hr-smith.com
During the Farnborough International Airshow, Elbit Systems uncovered the helicopter version of its Skylens wearable head-up display for enhanced flight vision system (EFVS) applications. According to Elbit Systems, Helicopter Skylens supplies a true “out of the cockpit” view, showing flight symbology for day and night operation in severe weather conditions. In limited visibility conditions, the pilot is able to fly eyes-out due to the wide field of regard display. Similar to its commercial counterpart, Helicopter Skylens is a lightweight, easy-to-install device, much like a pair of sunglasses. Skylens is a part of the Clearvision EFVS family, displaying high-resolution symbology and video on a transparent visor, providing pilots with head-out capabilities.
Bell Helicopter is offering a new autopilot kit designed to integrate with the Garmin G1000H avionics suite in the Bell 407GX. The option is currently available as a kit for the Bell 407GX in the U.S. and Canada. FAA and Transport Canada has certified the autopilot for visual flight rules (VFR) operations. It features two-axis functionality with cyclic force trim and a stability and command augmentation system (SCAS) available at all speeds with altitude and heading preselects. Derived from the Bell 429 digital automatic flight control system, the autopilot integrates with the Garmin G-1000H’s navigation modes and display and also incorporates audio for caution alerts and mode annunciations. It is also compatible with a night vision imaging system (NVIS) and automatically disengages during heavy turbulence or extreme flight altitudes.
