strafer,
Do I teach my students what?
That a fuel miscalulation is stupid and careless, which is what I said?
That they'll be prosecuted for it, and that in SOME cases I'd disagree with that?
Anyway, I teach on the R22, which actually DOES have accurate fuel gauges,or so I've always been told. It also has a fuel warning light, which comes on when you have five minutes of fuel left, and the light is checked before each flight. And five minutes is enough to land a helicopter safely - we don't need runways.
So your point is??
