Nope. That doesn't show that you understand the RAA legal framework and approved sources of data. Most of it is about this, not technical matters. Much like the Maintenance Procedures Course for ABAA and ABEA, with a mild dose of basic technical questions. Cheers, Paul

Ethanol is something you can test just about every time you take a fuel sample. It is really easy. Take your usual sample, then place it in a test tube with a few ml of water at the bottom to a mark on the tube. Shake it up and see if the meniscus moves down. If it does, you have Ethanol or Methanol. A commonly sold fuel tester for GA is even calibrated so you can see the percentage of Ethanol with this test.
