What is the Best Rate Single Engine (Vyse) speed?

Vyse is the speed that gives the maximum rate of climb with one engine inoperative. It’s found from the aircraft’s OEI performance data and represents the best balance between available thrust from the remaining engine and the drag you’re flying at. At this speed, the aircraft climbs fastest after an engine failure during takeoff or initial climb. For this scenario, the aircraft’s performance charts designate 125 knots as Vyse, meaning that at this airspeed you achieve the greatest climb rate with one engine out under the specified weight and configuration. Going slower would waste potential climb rate, while going faster increases drag and reduces climb performance, so those other speeds don’t yield the maximum rate of climb.
