Sandel Avionics has announced it has reached an agreement with the FAA that would consider helicopters operating under Part 91 or Part 135 rules as candidates for Field Approval installation of its new ST3400H HeliTAWS unit. Simplified installations would be done under the guidelines in FSAW 02-03A, which include an operational flight check as described in CFR 91.407. The only FAA involvement for a HeliTAWS installation will be to approve the RFMS (Rotorcraft Flight Manual Supplement) generated by the installing agency, although a flight evaluation, conducted by an FAA or DER test pilot, may also be necessary.
Sandel Avionics, located in Vista, California, is a privately held company that provides compact integrated display systems for business aviation, air transport and regional, and rotary-wing aircraft. Recent successes include the company's best-selling, turbine-class ST3400 TAWS and its 4-ATI retrofit primary flight displays, and its new HeliTAWS is the helicopter industry's first complete HEMS solution.
