What is the best angle of climb speed (Vx/Vxse) in KIAS?

The best angle of climb speed, often referred to as Vx or Vxse for single-engine operations in a multi-engine aircraft, is the speed that allows the aircraft to gain the greatest altitude over the shortest horizontal distance. For many multi-engine aircraft, this speed typically falls within a specific range depending on the aircraft's design, weight, and configuration.

In this case, an indicated airspeed of 82 knots is identified as the optimal Vx/Vxse speed for the aircraft in question. This speed provides an effective balance between being high enough to maintain control and performance and low enough to ensure maximum climb capability. At this speed, the aircraft is best positioned to clear obstacles in the climb path while optimizing lift to drag ratio, which is crucial during takeoff and initial ascent phases, particularly when there is an engine failure situation during climbing.

The key aspect of this choice is that 82 KIAS is recommended for various multi-engine aircraft and is consistent with the approach to maintain the best performance during critical phases of flight.
