As a matter of interest, Pilots in my airline are authorised to complete some CFDS procedures on the A320. Where some MELs have Maintenance action which involve CFDS procedures, we also have an Alternative Procedure which allows suitably trained aircrew to complete it. Use of the procedure needs authorisation from Maintrol and needs to be annotated correctly in the tech log, and it's very handy for some of our out of the way destiantions which don't have maintenace support.
And it's not a ''get you home'' procedure either. We can dispatch from base knowing the CFDS procedure needs to be used on the transit check away from base. I find I end up using it about once a year. No other airline does this to my knowledge.
