CONF iture, I guess the answer you are giving here may be type-specific, as you quote a
FCOM 1.22.30 reference ... ? What is that reference, please?
Secondly, let me pose a question. If what you say above is correct, then what happens if you are in ALT GREEN at 5000' on QNH and the QNH changes. You therefore change the QNH subscale - does the aircraft re-establish at 5000' on the new QNH or, as you seem to be suggesting, does it remain at the previous "pressure level"?
