Is VATSIM free, and what do you need to get started?

VATSIM is free to join and free to use. You need a VATSIM account, a compatible flight simulator, and a free pilot client such as vPilot for MSFS or xPilot for X-Plane.

The hard part is not the price. The hard part is confidence: understanding clearances, reading back instructions correctly, and managing the aircraft while talking to human controllers.
