Thrust lever control on takeoff

[narapusnapus]

Hi all,
Let’s say during a takeoff on an a320 ,the CM2 is the PF and there’s unreliable airspeed during takeoff-who applies TOGA-The PF (CM2) or the PM (CM1)? Since thrust levers are always with the CM1 until V1 if I’m not wrong?

Would depend on the airline's SOPs, which may differ significantly between Airbus-style and Boeing-style auto-throttle design, or they might try to make this procedure similar...

Hello,
If you have diagnosed unreliable airspeed below V1 (hopefully with the 100kt call), I would hope the CM1 with their hand on the thrust levers would reject the takeoff. If the issue was diagnosed after V1 the CM1 hands should not be on the levers and they would be CM2's to set TOGA 15deg etc and continue with memory items and the unreliable speed QRH.

Depending on how unreliable airspeed was diagnosed, I could see it resulting in no V1 call despite the airplane physically going faster than V1. Would be an unusual failure, though.
