AYESAŞ HTAWS is designed to reduce the risk of Controlled Flight Into Terrain (CFIT) accidents of rotary wing aircraft by providing increased situational awareness of the surrounding terrain and obstacles, mainly during the cruise phase in Visual Meteorological Condition (VMC) and in Instrument Meteorological Condition (IMC) under Instrument Flight Rules (IFR).
HTAWS will take inputs such as position, flight data, and terrain and obstacle information. HTAWS algorithm processes the input and generates display information, aural alerts and visual alerts to meet the intended purpose of HTAWS. The software may be integrated in any avionics computer and display system by the use a well-defined ARINC 653 compliant interface.
