I meant was that it wasn't particularly unsafe on this occassion because of the basically unused taxiway prior to it
I still have concerns about the way your thinking about this...
It shouldn't even cross your mind about the taxi way prior to the threshold - it's completely irrelevant what's before the threshold. I know you know it's completely unacceptable, but it's also completely unacceptable that your even thinking about the taxiway before the threshold. If a student at our school thought like this, I have to say they'd be grounded.
That said. Everyone fails at some point in their life, if we didn't they're wouldn't be a course or test! The flight test and piloting isn't just a test of your flying ability - it's a test of your decision making ability, i.e knowing your off glideslope and going around, your maturity and ability to recognise your errors, move on and learn from your mistakes. What separates a real pilot from a someone who happens to fly is how you approach your failure and learn from it...One who mulls on it simply just flies.
Safe skies!
