Yesterday I went back to the airfield for Hour Building: Cranfield – Grafham water – Sywell – Cranfield.

I took my friend up for the first time on what is quickly becoming my go to local flight route for people on their first flight.
From Cranfield I did a left turnout and headed over Bedford and up towards Grafham Water (11 mins). From here we then head west over Wellingborough and overhead Sywell airport (18 mins). We then head south back to Olney (8 mins) which is a VRP (Visual Reporting Point) for Cranfield, so I request the join from here.
It was actually a really nice day for a flight which was good considering the weather on Saturday was awful. It was also the 28th day since my last flight and my school has a rule that any time outside of this you have to do two circuits with an instructor first which can be an annoyance when you are trying to build P1 hours.
Something weird did happen on this flight however. As we were setting out past Bedford, the low voltage light came on twice. I found this strange as the Amp meter was not showing a discharge at all. I was considering a return to Cranfield when the light decided to stop lighting up and as Grafham water is right next to a runway at Little Stanton I decided at that point it was better to continue.
The light stayed out until the leg from Sywell to Cranfield. This was 7.5 mins flight time and around 3 mins in it started doing it again, but didn’t go out at all, just constant flashing. Once again the amp meter was not showing a discharge from the battery. I had planned to go into the circuit, but I decided it was better to land and report it to the school so they could investigate.
I am curious to find out what the issue was next time I go up there, unfortunately this won’t be for a month now as I will be away on a much needed break towards the end of the month for a few days.
