The callout of V1 is to start at V1 minus 5 knots to ensure that the call is complete by V1. And our airline got this from boeing.
AS to the simulator problem in the 737-300, it was in the USA, it did happen and they fixed it. Imagine that, a technical problem with a high tech gadget. And at the time, the 737-300 was a new plane.
THE thumb thing works when you are airborne , not so much on the ground. But on the ground if you are ''visual'' you can see yaw as the plane heads towards the weeds without correction.
