Centaurus,
Once again I beg to differ. Whilst I agree that it is good airmanship to cross check GS and Airspeed, not everyone does it. Time is an issue here.
As both ASIs are dead until 30 kts in the bus, you have about 15 secs to determine if you have an issue with the ASI at the same time doing the T/O calls and engine instrument monitoring. 100 kts comes up in about 20-25 seconds from the application of Flex(once again I am using the bus as I do not remember Boeing at all).
I think it is a mistake to continue the T/O and take an unsafe aircraft into the air. I know that we have procedures to deal with unreliable airspeed but the need to identify the problem correctly makes it less risky to stop rather than go as far as I am concerned.
