Chelton EFIS STC'd For Bell/Eurocopter Models

Chelton Flight Systems has received FAA supplemental type certificates for its FlightLogic synthetic-vision electronic flight instrumentation system for the Eurocopter AS350 and AS355 and the Bell 407. This is the first STC for a Eurocopter model, according to David Thomas, Chelton's rotorcraft program manager. The AS350 models include the C, D, D1, B, B1, B2, B3 and AB. The AS355 STC includes the E, F, F1, F2 and N models. Chelton already holds STCs for the system on the Bell 206.

The EFIS is coupled to the SAGEM AP85 autopilot for all LNAV procedures, including approaches. It features the Chelton primary flight display with forward-looking synthetic vision and a multi-function moving map display. The synthetic vision is based on computer-generated mapping, and includes towers, antennas, buildings and other obstacles. The system introduces two unique capabilities to the helicopter market: highway-in-the-sky navigation symbology with 3-D GPS guidance for en-route flight and instrument procedures, and hover vector, which provides the pilot with a real-time drift vector that allows zero-zero takeoff and landing and is designed to eliminate whiteout/brownout accidents, Thomas said.


The company is working toward getting STCs for additional helicopters, with interest coming from other Bell and Eurocopter operators as well as an AgustaWestland operator, Thomas said.
