If your plane doesn't have V2, what speed do you fly?

• A. V2
• B. VYSE- single engine best rate of climb speed
• C. VREF
• D. IAS

Answer: (B)

When a plane doesn’t publish a takeoff safety speed for two-engine situations, you rely on the speed that gives the best climb with one engine inoperative. That speed is VYSE, the single-engine best rate of climb. It’s chosen because it maximizes climb performance after an engine failure, helping you maintain obstacle clearance and reach a safe altitude with one engine out. V2 is a takeoff safety speed used when V2 is defined, but if it isn’t published on this airplane, VYSE is the appropriate climb speed. VREF is an approach/landing speed, not used for takeoff, and IAS is just indicated airspeed, not a specific recommended takeoff speed.
