Sandel Receives TSO For Advanced HeliTAWS™ Terrain Safety System


Sandel Avionics has announced Technical Standard Order (TSO) approval for its revolutionary HeliTAWS heli- copter terrain safety system, which adds Sandel’s proprietary TrueAlert™ nuisance-alert elimination technology, off- airport landing capability and high-resolution 3-D terrain display capabilities to basic Class A HTAWS functions. The result is that HeliTAWS is expected to significantly increase the safety of such demanding


Altimeter indicator. Sandel’s TrueAlert™ technology increas- es pilot confidence in terrain technology by eliminating nui- sance alerts, a significant prob- lem with all existing terrain warning products that limits their usefulness in helicopter operations. With TrueAlert, pilots can safely take off, cruise, hover and land at off-airport locations without triggering nui- sance alerts, while still receiving the established benefits of Class- A terrain warnings during the entire flight. The system is com- pletely automatic and does not require pilot management of the phase of flight. “We wanted to develop a breakthrough that would sig- nificantly raise


nuisance alerts,” he noted. “The difference with


HeliTaws is that our system works exactly as the pilot expects in all phases of flight. This includes the capability off-air- port landings in terrain-chal- lenged environments, which was quite a technical design chal- lenge,” Block concluded. In a single 3-ATI enclosure,

ter missions as HEMS (Helicopter Emergency Medical Services); offshore oil rig operations, tactical military support, search and rescue, and airborne law enforcement. Far exceeding the require- ments of FAA’s TSO C194, which governs en route HTAWS, HeliTAWS is a ruggedized, self-contained sys- tem with a high-resolution dis- play that retrofits by removing and replacing an existing Radar

the HeliTAWS system incorpo- rates an HTAWS computer with TrueAlert algorithms, terrain and obstacle databases, highly adaptable interfaces for digital and analog avionics; and an ultra-high resolution 3-D ter- rain display. In addition, it is capable of acting as primary Radar Altitude indicator (with a built-in Minimums setter) compatible with virtually all radar altimeter systems, to vastly simplify retrofit installation. It can also display traffic input from TCAS, TAS or TCAD sys- tems, allowing it to become the central safety display in the helicopter. HeliTAWS is also available with Sandel’s proprietary on-demand MIL- STD-3009 Class B NVIS optics.

the bar on HTAWS performance and expectations,” said Gerry Block, Sandel’s president. “The universal complaint with all existing systems is that during the performance of normal heli- copter missions, the pilot gets unnecessary and distracting nui- sance alerts. In contrast, HeliTAWS completely eliminates

Jim Garrett Joins REBTECH As Vice President Of Operations


Longtime night vision and


aircraft lighting pioneer, James R. “Jim” Garrett has joined night vision specialist, REBTECH as part of the com- pany’s ongoing expansion and capability enhancement. Garrett brings with him over 40 years of aircraft instrument manufacturing and repair experience as well as a broad background in night vision lighting technology. In 1987, Jim was awarded the aerospace crew station lighting certifica- tion from the Aerospace Lighting Institute and he also holds a patent for aircraft instrument lighting design. In addition, Jim served as the NVIS lighting co-chair for the RTCA special committee SC- 196 during the development of the DO-275 Operational Requirements for NVG imple- mentation into the National Airspace System (NAS). Jim Garrett will maintain an office at the REBTECH facility located in Bedford, Texas where he will be an important part of operations focusing on the research and development component of the company. REBTECH is currently involved in several large gov- ernment contracts around the world to convert airplanes and helicopters to night vision
