The alert that gets you back in the seat.
A controller logs on at your departure, destination, or along the route and your phone tells you. No more flying unicom under a staffed center.

Questions
Which networks are supported?
VATSIM and IVAO for traffic and controllers. Two-way messaging works on VATSIM through vPilot (MSFS) and xPilot (X-Plane).
Does Cobalt replace my pilot client?
No. You still fly with vPilot or xPilot. Cobalt adds a small plugin or relay so your messages pass through your own session.
What does the controller see?
A normal private message from your callsign. Nothing about Cobalt.
Is voice supported?
No. Cobalt handles text private messages and alerts. Voice stays in your pilot client.
