What you're working

Real airports

Four real airports — St. Louis, Atlanta, Denver, and Seattle — built from published FAA data: runways, waypoints, and procedures, laid out on a live radar scope.

A frequency that talks

Every instruction gets a pilot readback, and the frequency chatters with check-ins and traffic, voiced right in your browser.

Real procedure

Runway flows, wake-turbulence separation, handoffs, and in-flight emergencies: the same rules a real approach controller works.

Four airports live — St. Louis, Atlanta, Denver, Seattle. More on the way.

On the scope

The KSTL approach radar scope: seven aircraft on the arrival flow, each with a callsign, altitude, and speed data block, laid over the real runway layout, range rings, and the Missouri and Mississippi rivers.
Real airports. KSTL runways, fixes, and rivers, built from published FAA data.
The same scope with the radio exchange showing: green controller instructions and lavender pilot readbacks stacked bottom-left, a pilot reading a heading and altitude back to the controller.
A frequency that talks. Issue a clearance and hear the readback come back.
The scope during an in-flight emergency: one aircraft squawking 7700 with an EMERG data block near the field, the rest of the arrival flow still to be worked around it.
Real procedure. Then a strip goes 7700, and the plan is yours to rebuild.

Facility certification

Earn the patch.

Work a facility clean, long enough, and it becomes yours to wear. Facility certifications are coming with progression, one embroidered scope at a time, starting with KSTL.
