Back in the day, a particular nasty trainer gave me a thrust reverser deploy (on the sim) at full power at rotate. (Eng remained at full power) Don't think it was even possible on a 737 but my call of feather it (just come of turboprops) ensured it was shut down by the capt. we were 30 deg off heading but back on track by 200 ft. My point being sometimes s** the qrh just do whatsynecessary.(remember full rudder & full aileron)
