Hello!
I wondered whether a client capable of facilitating approach procedural (i.e. non-radar) could ever be considered for airports that have that position in real life? It is a very different skill from approach surveillance (radar), as it involves relying on pilots reporting at certain points, and time-based separation to be applied through holding and estimated times at certain fixes. The client would need to provide the controller with the flight progress strips for each arriving / departing aircraft, with the ETAs for certain points, which the controller could either print - or indeed drag around the screen - as the aircraft arrives at each point.
I'm not suggesting this be a priority - just an interesting idea to consider down the line :)
Cheers,
Caspian
