Unless you have EVS
Planes also depart, runways inspections happen etc.
In the British Isles there are probably no more than 50 controllers with experience of operating remote towers. Half of those are here and the overriding comment after first using it live was that it was the same but different - and noone felt uneasy or unwilling to use it.
It may be worth reminding that at the ATC colleges (and at most ATC units), the aerodrome control simulators basically are just a load of screens. It is how we simulated camera and screen failure in our training.
If it is OK to train an ab initio and is approved as part of the training organisation then why would a remote tower be any different?
