Nseu,yes I meant no failure messages on Ecam.The problem I experienced was on one air data system producing erroneous data.Airbus are saying it was probably pitot icing but the failures we had affected both the speed and altitude indications.Some of the subsystems recognised that the data was faulty others didn't.
I should also add that there was no evidence of any airframe icing whilst this was occurring.
Thank you for the links
