Agreed that transonic loads could be highly non-linear. However, the locks are out during the period the speed is reducing through the transonic regime in the test flights, though admittedly at a somewhat higher altitude. If there was marginality in holding the feathers in the correct position at any (high) speed why plan to withdraw the locks above some (low) speed limit?
