Does VMCA vary with aircraft weight?

Yes, VMCA, or Minimum Control Speed in the Air, can vary with aircraft weight. As the weight of the aircraft increases, the VMCA typically increases due to the higher control forces required to maintain directional control with one engine inoperative. Heavier aircraft may require a higher airspeed to achieve effective control, impacting the performance during critical phases of flight. Therefore, pilots must be aware of the aircraft's weight when determining VMCA during operations.
