It took quite a bit of effort with ForeFlight to support TEC routes in Southern California. There were several issues with depiction of routes including radial routes, radials to intercept airways using non ICAO syntax, radials to intercept a localizer, and the fact that the ATC computer would only recognize the routes as exactly defined in the Chart Supplement or using the TEC route name. If the route is not recognized, it is assigned anyway using the TEC route name, so pilots could only get cleared as filed when the name of the route was filed. ForeFlight had to determine equivalent routes that complied with ICAO syntax and file using the TEC route name. If you expand the TEC route by tapping on the FPL editor TEC route name object, tapping on expand, it will display the details of the alternate route. This is the form that the route is interpreted within ForeFlight as and also the form that is sent to a panel via FS210/FS510.
