What is the Best Angle Single Engine (Vxse) speed?

Best Angle Single Engine (Vxse) is the speed that yields the steepest climb path with one engine inoperative. It’s the point where altitude gain per horizontal distance is maximized, which is exactly what you want to ensure you can clear obstacles after an engine failure on takeoff. For this aircraft’s OEI performance data, that steepest climb angle occurs at 125 knots. Going slower risks approaching stall or losing controllability with only one engine producing thrust, while going faster increases drag and reduces the climb angle even if the climb rate might be higher. So 125 knots is the speed that best achieves the required obstacle clearance when operating OEI.
