I stand corrected on the minister decree of FR use if in force as applicable.
Airbus should have automated crosscheck between the the FCU selection and MCDU. Same as the recently implemented useless THS reminder (narrowbody).
The method of transferring critical QNH value to airborne craft by voice only will be hopefully become obsolete soon. No idea when and how.
The NPAs should have a RA hard crosscheck somewhere (1000 afe) PUBLISHED by the AIS similar to G/S validity with DME or marker overflight.
Keep the ideas coming...
