Brief Description: Annunciator Warning Lights Indicator Panel

Feb 3rd 2012 I am still working on the avionics/panel. Yesterday while at work on a Friday, I have designed the Annunciator Warning Lights Indicator Panel that sit just above the “radio” stack. This indicator panel maybe somewhat redundant as the Skyview does have ways of connecting the items listed to be displayed on the pilots Multi-Function Display, and I plan to do this, but I feel that in panel indicator lights for the following is worth pursuing. The seven indicator lights are as follows: Left Door (red LED), Right Door (red LED), Oil Pressure (amber LED), Pitot Heat (red LED), Auxiliary Fuel Pump (amber LED), Flaps Down (red LED and Flaps Up (green LED). When the X-10 is powered ON, the Left and Right Doors annuncator lights are On (red) when the door pins of the X-10 are not fully engaged (e.g. the doors are open). Closing the doors correctly extinigshes the indicator LED’s. Then the Oil Pressure light is logic On (amber) until the oil pressure has passed ~15 P.S.I, then using reverse logic (because the Hour Meter also uses this signal) turns Off the indicator light. This is necessary because the Skyview takes a few seconds to boot and does not indicate if the Oil Pressure is OK during this critical engine startup period. Pitot Heat is ON (red) when the Pilot or Co-pilot activates the panel switch that enables the Heat to the Dynon Pitot tube. This is a return signal coming from the Dynon avionics package located in the left wing. The Auxiliary Fuel Pump is ON (amber) when the Pilot or Co-pilot activates the panel switch that powers the auxiliary electric fuel pump. This normally is just before engine startup, switching fuel tanks, and before landing or in go-around. The Flaps Down LED (red) and Flaps Up LED (green) are activated from the panel switch or the Pilot/Co-pilot switch when taking off, landing or performing go-around maneuvers. Time about 10 hours including design
