Your neighbour Airbus pilot likely has access to the Airbus-produced Flight Crew Training Manual. The FCTM has very clear guidance on how to handle the UAS abnormal and/or ADR failures.
The following, from an FCTM in early 2007, is the essential part of the response:
PART 1: MEMORY ITEMS
If the safe conduct of the flight is affected, the flight crew applies the memory items. They allow "safe flight conditions" to be rapidly established in all flight phases (takeoff, climb, cruise) and aircraft configurations (weight and slats/flaps).The memory items apply more particularly when a failure appears just after takeoff. Once the target pitch attitude and thrust values have been stabilized, as soon as above safe altitude, the flight crew will enter the 2nd part of the QRH procedure, to level off the aircraft and perform trouble shooting. This should not be delayed, since using the memory item parameters for a prolonged period may lead to speed limit exceedance.
PART 2: TROUBLE SHOOTING AND ISOLATION
If the wrong speed or altitude information does not affect the safe conduct of the flight, the crew will not apply the memory items, and will directly enter the part2 of the QRH procedure.
Airbus also produced the following in September, 2006:
