What is the Best Angle (Vx) speed?

Best Angle of Climb speed is the speed that gives the steepest climb path, meaning the greatest altitude gained per unit of forward distance. You use it to clear obstacles after takeoff, sacrificing some rate of climb for more altitude gain over a shorter horizontal distance. Because achieving a steeper climb angle relies on flying slower, the Vx value is the slower option among climb speeds. The faster options, while they may deliver a higher climb rate, produce a shallower climb angle because you’re covering more horizontal distance while climbing. So the steepest path—best for obstacle clearance—is found at the slower speed. After obstacles are cleared, you switch to the higher-speed, best-rate-of-climb speed (Vy) to gain altitude more quickly in time.
