Viking Series 400 Twin Otter to fly Safe Flight Angle of Attack

Safe Flight Instrument Corporation, pioneers of Stall Warning and Angle of Attack sensors for all segments of the aviation market, announced today that the Safe Flight Angle of Attack (AoA) System has been selected as standard equipment for the Viking Series 400 Twin Otter.

The fully qualified and TSO'd System is comprised of a Lift Transducer, Computer and a Speed Indexer. The Speed Indexer provides the pilot heads-up guidance to Approach AoA. The Computer provides ARINC outputs to drive Low Airspeed Awareness (LAA) and AoA displays on the Primary Flight Display. Safe Flight's Lift Transducer is a heated leading edge sensor and is Flight Into Known Icing (FIKI) capable. Safe Flight is a leading supplier of AoA/Stall Warning systems to all segments of the aviation market.

Allowing for slower approach speeds and increased awareness of wing loading during maneuvers, the Safe Flight system provides instantaneous stall trend and AoA information with best short field approach and best climb angle aiding the pilot of utility aircraft, such as the Series 400 Twin Otter, during backcountry and unimproved runway landings. Any factor which affects angle of attack is accounted for in the Safe Flight system, including flap and gear changes, wind gusts, ground effect and weight differences, providing an additional measure of safety in extreme operating conditions for which the Twin Otter's performance has become renowned.
