Narrative:
During flight left engine vibration indicator trended higher until reaching amber caution range. Following QRH procedure; throttle was retarded until indications were out of caution range. Planning for potential engine shutdown; single engine approach and landing procedures reviewed; APU started; landed with non normal flap setting for 2 engine approach. Flaps 20 degrees chosen for dramatically reduced power on 1 engine and following procedures in accordance with single engine approach; landing; and go-around contingencies.
