Why Choose Annunciation....
Complex systems allow the average person to enjoy the benefits of modern technology. Human capabilities to monitor complex systems is surprisingly limited. Training and practice increase those capabilities but in every flight there is a period of time that a gauge or indicator was not properly monitored. If that gauge is oil pressure in an aircraft without a warning system the only warning the pilot will have is the sound of the engine failing. 20,000 hr flight instructors are not immune to gear-up landings. A distracted pilot turning final could let too much airspeed bleed-off and enter an accelerated stall. All of these issues and many more can be fatal. NASA and every aircraft manufacturer has included ACW systems in there vehicles. Even your fathers car had rudimentary warning lights because those indicators can save you lots of money and maybe even your life.
