Hi Mac
All things considered, it would be safer to take all probes off line and extinguish IAS displays, followed by a message on the PFD. "airspeed INOP".
It wouldn't matter whether it was real or not, if real, the message on the ECAM is [/B]UAS / SET PITCH / MONITOR POWER[/B] if it is not real,
TEST/ONLY.... Three's your startle "drill" for the trip!!
