Cat 3 single vs Cat 2 on A320
Ladies and Gentlemen, once again, I am in need of your technical expertise.
Looking at FCOM SRP 01-70 for the definitions of Fail passive system, I am a bit perplexed by the following:
An auto. landing system is fail passive if, in the event of a failure, there is no significant out of trim condition etc, but the landing is not completed automatically.
What if that failure results in a capability degradation to CAT 2? The landing could still be completed automatically.
Let's assume we are executing the approach and above 1000 feet, FMA goes from CAT 3 single to CAT 2. If the RVR allows it and we have time to change the minimums in the MCDU, we could continue to a CAT 2 Autoland.
So why is Airbus stating that "the landing is not completed automatically" after a failure from a fail passive system?
What am I missing?
Thank you
