Aeronautix Introduces Aural Warning and Annunciation System for King Air 300/350 Aircraft
The Aeronautix AWAS provides voice alerts when engine temps or torque are exceeded in critical maneuvers.
Aeronautix is awarded an FAA STC for its aural warning and annunciation system (AWAS) which the company is manufacturing and installing on the Beechcraft King Air 300 and 350 series aircraft. The system, designed to integrate with the Collins Pro Line 21™ avionics suite, improves situational awareness by giving aural voice warnings to pilots, avoiding potential engine damage due to over-temp or over-torque conditions.
Pilot workload during critical phases of flight, such as takeoff and missed approach, can distract crew from serious engine limitation exceedances, resulting in damage costing hundreds of thousands of dollars for repairs. However, with AWAS, if an engine exceeds temperature or torque limitations in any maneuver, an aural voice callout informs the pilot and crew that immediate action is required, supplementing the visual indication on the engine multi-function display (MFD). The aural voice warning, “MONITOR TEMPERATURE,” is triggered when engine temperature exceeds 820°C and will continue repeating “TEMPERATURE” every five seconds until the condition no longer exists or is manually silenced by the crew. If torque exceeds 102%, an aural voice warning will call out “MONITOR TORQUE” and will repeat the word “TORQUE” every 15 seconds until the condition no longer exists or is manually silenced by the crew. These aural warnings are supplemented by amber and red visual annunciation on the AWAS control panel.
The non-invasive, on-site installation takes about 12 hours and consists of wire harness connections to the existing 429 data bus in the King Air. The AWAS is mounted in the center console on civilian aircraft. It is authorized for other locations in military configurations and replaces the Cobham 630A-000 warning amplifier.
With PT6 engine overhauls averaging $300,000 or more, the AWAS will pay for itself with a single voice callout.
