GerardC;
I am just saying that, from a notary/Court point of view : AF book mandates "AP/FD/ATHR OFF ; CLB thrust/5° NU" each time ALL IAS are unreliable or if THE unreliable/faulty IAS cannot be "clearly" identified
Any one of these two conditions is considered to be "affecting flight safety".
Okay, thanks very much.
Wow.
