A question for examiners:
I always check the altitude indication after setting QNH.
As I know the apron elevation, I cannot make a big mistake. But I would not notice a one hPa mistake, as it is to small to be significant.
(eg If actual QNH is 1023.9, the A/G will say 1023, if I set 1024 by mistake, I wont notice the error by checking the altitude indication).
Q1: Would it be a fail at this point?
Aligned on threshold, I always check altitude is in line with threshold elevation before taking off.
Then again, I would not detect a wrong QNH setting of only 1hPa.
Q2: Would it be a fail at this point?
It's only in flight, after my first Freda check, that I would compare QNH set and QNH written on my kneeboard.
Then I would correct it.
Q3: If everything else is ok, would I fail the test?
