My eyeballs don't often deceive me, and I've always used the jamjar method up to now.
I recently worked for a company that insisted on using test paste with Avgas - they are a very respectable company too. Given that their premises and setup are immaculate, I don't really think they need to use the paste, but I'm flying a different machine now - a 1941 aircraft with an equally old tank kept in a dark and dingy hangar. The fuel is stored on site in an ancient underground tank, and delivered by a 1930s hand crank pump (it's a great setup, honest). But I want the extra confidence provided by the test paste. OK, so I could walk outside and hold the jar up to the light, but I'd like to inject a bit more professionalism into the setup. A test jar kept with date of test etc., I'm sure you know the score. I guess that a tube of paste isn't going to break the bank compared to flying vintage machinery...
So dammit, I'm going to spend the money! |
