One of the distractions was a phone call from my avionics shop in Hartford, Connecticut. Dave, the shop manager, wanted to professionally convey the status of my Arrow while it was being fitted with Garmin’s ADS-B unit, the GTX 345 transponder. A decision involving the antenna, along with some other minor issues, required my input. All good stuff, but I know better than to allow distractions into the cockpit, even while parked at the gate. My bad. The punishment was that various people and various issues required my attention all at the same time.
