PUSH NOTIFICATIONS • Reminders for your favorited events, at the lead times you choose • VATSIM private messages, including a controller's contact me • SELCAL alerts Private message and SELCAL notifications need the free vPilot Push Notification Plugin, installed on the Windows PC you fly from. You can download it from inside the app, or at vatradar.io/vpilot-plugin. NETWORK STATS Connected clients and unique users, pilots online, controllers broken down by position, ATIS stations and prefiled flight plans. ACCESSIBLE BY DESIGN VATRadar is built by a blind developer and sim pilot, so VoiceOver is not an afterthought here - it is how the app gets used every day. Every screen, list and control is designed to be navigated comfortably without sight. The same care extends to the rest of Apple's accessibility features. VATRadar uses standard iOS controls throughout, so it works with Larger Text, Bold Text, increased contrast and Voice Control, and follows your Dark Mode setting. If something does not work with the accessibility features you rely on, that is a bug to be fixed, not a limitation to live with. FREE VATRadar is free. There are no ads, no in-app purchases and no subscriptions. Signing in requires a VATSIM account, which is also free. VATRadar is intended for flight simulation on the VATSIM network. The airport, runway, frequency, weather and ATIS information it shows must not be used for real-world flight planning or navigation. VATRadar is an independent project, and is not affiliated with or endorsed by VATSIM.
