What is the difference between a remote tower and a digital tower?
The terms overlap and are often used interchangeably, but there is a useful distinction. 'Remote' refers to location: the controller is not in a cab at the airport. 'Digital' refers to method: the operation is built on cameras, sensors, and software rather than direct out-the-window vision. A tower can be digital without being remote (a digital cab on the field) and the industry standard label, used by CANSO and EUROCAE, is 'remote and digital towers' to capture both. For most airports the business case combines the two: digital tooling delivered from a remote, centralized centre.
