I went flying yesterday and as I started the engine the first thing that I noticed was that the stormscope was showing a lot of activity. Strange... was my first thought, considering that we are in April and that is was really a CAVOK day in the Washington DC area... But... who knows. I took off went for a 1 hour flight landed and took off in order to fly back to Gaithersburg (KGAI). About 20 minutes into the flight my ASPEN switched over to battery mode. Strange... I scanned the rest of the panel and everything looked ok. I rebooted my ASPEN and it went online again. Then I realized that the JPI was showing 12.1 Volts instead of 14... So let's see what is going on... Breakers are in, everything else looks fine... let's recycle the alternator. No news, voltage was down to 11.9.
Note: I had my sister flying with me. She is a very scary flier, she had never flown in a small plane and this was her first time! She was really enjoying it! I did not want to scare her.
So now let's reduce the power consumption: i) Autopilot off, ii) let's just in case turn off the Garmin 795 in case I need it later, iii) turn off second radio iv) turn off alternator field (gave me 0.1 V). I also took my handheld radio out of the bag (just in case) (yes, it was charged).
As I had only 20 min of flight left I though that I could continue without any major issues. Just in case, I decided to lower my gear and flew slower with my gear down for the last 10 min of my flight.
I landed without any issues, my passenger never thought that anything was wrong (she just asked me after we landed why I had switched off so many things.)
Today my AI looked into the issue and it was a crimp connector that had broken. This is the second time around that this has happened to me. Last time it was about 14 years ago and I was flying into Manchester NH.
So nothing major, but interesting experience.
