Benefits

• Ever missed something important in your cockpit checks or scan that could have put you in danger? With the ever-increasing pressures of flying in busy airspace, it's too easy to do. Military and commercial aircraft have sophisticated monitoring and warning systems which watch the pilot's back while he or she focuses on demanding flight tasks where 100% attention is required, inside or outside the cockpit. In light-sports aircraft or experimentals, system monitors and cockpit warnings are often a mixed bag of individual warning lights or indicators scattered around the cockpit where they happen to fit. And while flat-screen displays can show a multitude of systems data and warnings, these are often densely packed and over-complex and abnormalities are easy to miss. And what about those situations where your early attention might avert a worse one developing? An actual fire might be difficult to miss, but what about high oil temperature or CHT, being in the wrong configuration or over speed, or fuel or oil running low, or low volts or vacuum? Might it be helpful too to be prompted to put your pitot heat on when icing becomes a threat, or to put your oxygen on as cabin pressure falls? Depending on your aircraft type, there will be other potential killers that could sneak up on you unnoticed. You've spent a lot on your machine, so spending just a little more for a system that alerts you when things need attention and helps to keep you and those with you safe, makes good sense. Any examination of FAA accident reports illustrates the point well: even the most experienced professional pilot can mess up! So we part-time, low-flight-hour aces might just need a bit of extra help.
