Hi folks
i have a flight to hong kong and shanghai in a week or so, i am not too familiar with that area and i would like to make sure i have got my altimetry setting procedures straight!
within Chinese RVSM atc instructions will be given in meters since they adopted the metric RVSM, and then the conversion chart must be referenced to, keeping the altimeter readout in feet - a 30m error is considered to be acceptable.
Based on your point of entry a buffer zone is then provided to adjust your altitude to the CFL - as a rule of thumb +100ft when entering metric RVSM from non metric RVSM for instance from kazakhstan, -100ft when exiting metric RVSM.
Below the transition level/altitude are you still meant to use conversion chart or you can switch the altimeter to the meter setting? and will they use QFE?
What about Hk?
Any other tip?
Many thanks
Diego
