THR button? The ONLY problems with the THR button are the way it is described in the Boeing manual and the indicated response when it is operated. Your ground training notes (assuming that you're Birdseed) should have included a little piece I penned many years ago on the THR button (or switch, if you prefer). It was intended to simplify matters but it may well have been removed. Shame really, 'cos, like Ronseal - "it does what it says on the tin"
