First Login

Launching Landline takes you through two screens: the splash login and the waiting screen. Live mode connects you to the live network; training mode keeps you isolated with other training users.

Splash Screen

The splash window shows:

Facility dropdown — pick your facility.
Login with VATSIM — opens your browser for OAuth, then returns you to Landline.
Training Mode toggle — graduation-cap icon in the bottom-left. Turns on training mode.

Live Mode

Live mode connects you to the real Landline network with other controllers.

Prerequisites

You must be connected to VATSIM with your ATC client.
Your VATSIM callsign must match a position configured at your facility.

Steps

Pick your facility.
Click Login with VATSIM and complete the OAuth flow in your browser.
Landline opens the waiting screen and looks for your VATSIM connection.
Once your callsign matches a configured position, you're placed on that position and the main window appears.

Position auto-detection
Landline matches your VATSIM callsign to a configured position automatically. If nothing matches, you'll stay on the waiting screen — check your callsign or ask your FE to add the position.

Training Mode

Training mode lets you use Landline without being live on VATSIM. Useful for practice sessions, walkthroughs, and FE testing.

Students

Click the graduation-cap icon to turn training mode on.
Pick your facility and log in with VATSIM.
On the waiting screen, enter the training code your instructor generated.

Training Staff

Facility staff listed on the Staff tab can generate a training code from the waiting screen to hand to students. Training users are isolated from live users.

FE Access

Facility Engineers open the admin panel after signing in via VATSIM.

Log in with VATSIM as normal.
On the waiting screen, look for the gear icon in the bottom-right corner. It only appears if your CID has FE access to at least one facility.
Click it. A picker shows every facility you can administer and how you got access (FE, Whitelisted, or Superadmin).
Pick a facility to open the FE panel.

See FE Overview for how access is granted and what each tab does.
