What is the Intentional One Engine Inop (Vsse) speed?

Vsse, the takeoff safety speed with one engine inoperative, is the minimum speed you must maintain after an engine failure during the takeoff phase to guarantee controllability and continued climb. It’s chosen so that, with one engine out, you have enough rudder authority and directional stability to maintain control and achieve a positive climb gradient to clear obstacles. In many light-twin training scenarios, this published Vsse ends up around the 110-knot range. The value you’re expected to use here is 110 knots, which reflects the airplane’s certified single-engine-takeoff safety speed. The other numbers are either too low to ensure safe control with an engine out, or not the published Vsse for this scenario. So, the best answer is the speed that corresponds to the published Vsse for this airplane, ensuring adequate control with one engine inoperative during takeoff.
