    Why the pressure error (1022-1013=9x30=270ft) is not part of the calculation? see attachments

    Hi,

    It's because you are given a QNH and the question asks you about an indicated altitude.

    The pressure correction would only come into play if you were asked for a flight level, the aircraft altimeter being set to standard 1013.25 hPa setting. Which is apparently not the case here.

      That is now clear! Thank you!
