OK, thanks that sounds plausible. Boeing being user friendly and Airbus being less so sounds familiar. Our SOPS do not differentiate between Boeing and Airbus however. The FMCs are all Honeywell I believe, but with different software for each of the 2 airframe manufacturers. THe ARINC databases you would imagine would be the samer however. Any other contributions, including aircraft type, would be much appreciated.
Cheers
