As some one has already said the crews are new to the Airbus at BRS. Judging by the above they did a good job in getting the job done. It doesn't really matter if the crew where in touch with atc or not. When they are presented with multiple failures i'm sure ATC will soon get the hint to clear the skies!
The report will make interesting reading. Good job it didn't happen at the end of a long 4 sector day!
