We are pleased to announce that FSHud - Traffic, a new built-in traffic source for FSHud - Air Traffic Control, is planned for release in the next few days.

FSHud - Traffic will bring both live traffic and scheduled traffic directly into FSHud - Air Traffic Control, without requiring any additional installation. It will work with any installed traffic model package and will provide a more realistic and dynamic traffic environment directly through FSHud - Air Traffic Control.

The live traffic system will provide coverage of approximately 80% of live commercial flights, with traffic data refreshed every minute. This will allow FSHud - Air Traffic Control to use real-world live flights as part of the simulator traffic environment, reflecting aircraft that are actually flying in the real world at that time.

In addition to live traffic, FSHud - Traffic will also include scheduled commercial traffic by airport. This will include most commercial arrivals and departures, synchronized with live traffic to provide realistic airport activity even where live traffic coverage is not available.

FSHud - Traffic will also support traffic based on the selected Flight Simulator time. When this option is used, schedules and a live traffic snapshot matching the selected simulator time will be used, allowing users to fly with traffic that better fits their selected time of day.

The feature will be compatible with MSFS 2024, MSFS 2020, Prepar3D v4, v5, and v6. It will also be possible to combine FSHud - Traffic with other traffic sources, allowing users to use it as the main traffic source or as an additional traffic source together with their existing setup.

Due to intensive cloud usage and live traffic provider costs, FSHud - Traffic will be available as a monthly subscription for 2.90 USD per month, with a free 1-week trial available for every user with an FSHud - Air Traffic Control license, including legacy licenses purchased from distributors such as Flight1 and Aerosoft.

An active internet connection will be required at all times while using FSHud - Traffic.

FSHud - Traffic is expected to be released in the next few days.

That should be a nice change from Ultimate Traffic.
