Sorry Zeke,
I should have known not try and be tech on this forum..... but now I've started.
Yes, Dual Radalt Failure gives Direct Law on gear down, autopilot disco... no argument.
There are known cases though where water ingestion at the radalt antenna has resulted in a no return signal. ie the A/C doesn't know the RadAlt has failed and so will not recognize the Dual RadAlt fault.
Along a similar line I've had a Radalt ramp up whilst cruising at FL330 and RA1(Amber) took over both sides indicating -5 feet and a host of ECAMS.... it's just a machine and will always find new ways to break.

If you believe that fine, I hope you never find yourself in such a situation.
Anyone with something constructive to add it would be appreciated.
Flamers move on thanks.
Sorry should have said FLARE MODE at 100' not law.... pedantics count?
