Where do the points Vx and Vy meet in aviation terms?

In aviation, the points Vx and Vy refer to specific airspeeds related to the performance of an aircraft during climb. Vx is the airspeed for the best angle of climb, which allows an aircraft to gain the greatest altitude over a given horizontal distance, while Vy is the airspeed for the best rate of climb, which allows the aircraft to achieve the highest altitude in the least amount of time.

These two points, Vx and Vy, converge at the absolute ceiling of the aircraft. The absolute ceiling is defined as the maximum altitude at which an aircraft can maintain level flight. Above this altitude, the aircraft cannot sustain flight due to insufficient power to counteract drag. In essence, at the absolute ceiling, the performance characteristics that define Vx and Vy no longer apply because the aircraft can no longer climb or even maintain altitude effectively.

Recognizing this relationship helps pilots understand the limitations of their aircraft's performance and the implications of reaching or exceeding these critical speeds and altitudes.
