Qatar: a hypothetical future state
2 airports assessed. 0 have no tower and meet a tier 1 to 3 rule (0 / 0 / 0). 0 towered airports fit tiers 1 to 3. A hypothetical set of 0 centres covers them. No national traffic table loaded.
Orange, teal, pink and grey dots are suggested tiers. Hollow rings are towered airports that fit a tier. White-ringed orange dots are hypothetical centres. Green outlined dots are remote or digital towers already listed on this site. Basemap: OpenStreetMap data via Protomaps.
What it could enable
- Already moving. 1 airports here are listed on this site as remote or digital (operational, trial or planned). See them.

| Tier 3: Remote advisory (AFIS-like) | 0 | 0 |
| Tier 4: Surface awareness only | 0 | n/a |
| Large hub, left alone | n/a | 1 |

Responsible implementation
A tier on this page is a starting question. These are the topics any real plan would need to answer. Public guidance:
- EASA ED Decision 2023/005/R, guidance material on remote aerodrome air traffic services
- UK CAA: remote aerodrome air traffic services (CAP 670 and approval policy)
- EUROCAE ED-240A, minimum performance standards for remote tower optical systems
- FAA Digital Tower Systems page
- FAA AIP Program Guidance Letter 26-06 (design approval is not operational approval)
- ICAO Doc 4444, PANS-ATM, the procedures that remote services must still meet
Safety case and regulator approval
Each service needs its own safety case and approval before it carries traffic. A design approval for equipment is a different step from permission to run a service. The regulator named in this site's records for Qatar: Qatar CAA.
Controller workforce and training
Remote work changes the job: new displays, new failure modes, and new competence checks. A plan would cover who moves, who trains, how existing controllers choose, and what happens to current staff and their conditions.
Communications and surveillance
Radio, video and surveillance links must meet the latency and quality the safety case assumes. Tier 1 and 2 airports need reliable cameras, redundant links and a surveillance picture for traffic that radar or ADS-B cannot see from the ground.
Contingency and redundancy
Every centre needs a fallback: a second path for data, a backup position, and a rule for what the airport does when a link fails (hold, divert, revert to advisory). Centres that serve many airports need a plan for losing all of them at once.
Cybersecurity
A centre is a single high-value target. It needs the same protections as other air traffic systems: segmented networks, supply-chain checks, logging, and tested recovery.
Community and labour engagement
Airports, airlines, pilots, unions, local governments and neighbours should be in the process before decisions, not after. Jobs can move away from small airports, and that is a real cost to a community.
