But do we know what IAS2 was displaying ... ?
The last time we did practice a scenario of UAS at low level, the initial clue that something was wrong came under the warning : WINDSHEAR WINDSHEAR WINDSHEAR
My airspeed was getting in the red, which made sense to me in case of windshear.
As per SOP my call was "WINDSHEAR TOGA" which implies to follow the FD, not to turn them OFF.
That's only when I heard the instructor word : "eh guys ..." that I took a quick look at the other PFD and could remember that one of the exercises for the day was UAS
not WINDSHEAR ... The appropriate call was then only made : "UNRELIABLE SPEED"
This is how things can get confusing sometimes.

This is not so much about the handling, but how the avalanche of warnings can just mean that : UAS, and how the energy of the PF should go on maintaining a normal pitch attitude for cruise and the energy of the PNF should go on the monitoring the PF performance. The only actions the PNF could perform would be to kill the FD and set the thrust at a normal thrust setting for cruise.
All the concentration and energy on aviate - This is not necessarily easy as the multiple warnings don't seem to stop.
This could be like suddenly switching from a walk in the park to seat in a formula one at 300 km/h
