I view this tool as a valuable learning resource. While I don’t see it as the ultimate long-term solution for air traffic control, it can serve as a stepping stone toward transitioning to VatSim. Although the monthly subscription cost might be a bit high, I recommend utilizing it for three months to refine your skills. Afterward, consider moving on to VatSim, where you’ll engage with experienced individuals. Many of us have invested more than $60-$90 in aircraft and airports, so the cost, in my opinion, is reasonable.
It’s free in the KRNO and KTRK area’s. KRNO has very long runways so you can use commercial airlines in that area.
