Pre-takeoff checklist
We just installed the Avidyne IFD440. I think we are going to like it a lot, based on the 2.4 hours we have flown with it so far. We were disappointed in one thing. The shop that installed it, did not know anything about the ability to monitor the standby audio frequency. I read somewhere that this was possible by only wiring a couple of pins to an unused switch on your audio panel. I have a KMA 24 (the -03 version) and do not have an adf in the plane. Is this as simple as running 2 wires from the IDF440 to the adf switch on the KMA 24? If so, can anyone tell me which pinouts from the IFD go to which pins on the KMA?
