Sandel Avionics last month delivered its first HeliTaws helicopter terrain safety system, to Metro Aviation of Shreveport, La., for installation in a Eurocopter AS350. Sandel received TSO approval for HeliTaws on August 16. The 3-ATI HeliTaws includes a high-resolution display that retrofits by removing and replacing an existing radar altimeter indicator. NVG-compatible, HeliTaws meets DO-160F helicopter vibration standards and has an MTBF of more than 10,000 hours. The retail price is $18,950.
