Many airports we control at could benefit from having multiple frequencies of the same type open to handle unexpected traffic surges. At the present time, that can only be done at the application level.
Here’s the feature request…,
Allow the ATIS controller to add additional frequencies for ground, tower and approach as needed. That ATIS info would flow to the server where other controllers would then see those frequencies available.
This would take the burden off the developers to add these frequencies for special events.
