Duenna refuelling error report - attempt at an explanation:
On my leg 12 from KPGA to KGCN, duenna reported errors associated with inflight refuelling about 2 minutes before I landed at KGCN. I had loaded 50 lbs of fuel, and on the flight I used 48.3 lbs (yes, I should have loaded more!!). However, I didn't actually run out of fuel before landing, and in fact the aircraft engine idled for about another 5 minutes on the ground before it did finally cut out.
I couldn't work out why Duenna recorded the error, so I flew a test flight, in the same Marchetti. I loaded just 6 lbs of fuel, took off from KGCN and climbed to about 10,000, and just circled waiting for the engine to cut. Before the engine cut, I got the same refuelling errors from Duenna. So it seems Duenna records an inflight refuelling error, even though I wasn't refuelling, just before I actually ran out of fuel. I landed it dead stick, here's the duenna record from that test.
To see whether this was something strange with the Marchetti, I repeated the test in a C172. Same 6 lbs of fuel, took off and climbed from KGCN, and started circling waiting for the engine to cut. Exactly the same Duenna errors recorded, before the engine cut (about 2 minutes this time). Again, landed dead stick, here's the duenna record.
So, what to do...
