A critical task combining perception and coordination
Air traffic control ergonomics examines how workstations, interfaces, the environment and work organisation fit the people providing the service. Its preventive purpose goes beyond avoiding back pain: it also includes making information recognition, communication and sustained work possible without unnecessary demands. Generational succession adds the need to preserve knowledge and prepare new colleagues without turning age into a label for capability.
A tower, an area control centre and a training environment do not have identical demands. Before recommending an improvement, the tasks, systems, interaction with other positions and scenarios that change workload need to be defined. This article develops assessment and management criteria. It does not prescribe operational aircraft separation instructions or replace the provider’s approved procedures. Workplace health and operational safety require coordinated attention, while their distinct responsibilities and decision processes remain clear to everyone involved.
Observing work before changing the workstation
Assessment can begin by following a complete sequence: preparation, taking the position, periods of activity, coordination, handover and recovery. Useful observations include where information is sought, which actions require reaching or turning, which communications overlap and which adjustments are skipped because they are difficult. Observation must be agreed with operational managers and should not introduce distractions during service.
The historical 1995 FAA/Volpe technical checklist raises questions about visibility, reach, control layout and environmental conditions. It is a user-centred design reference, not current certification or a source of mandatory dimensions for a modern console. The editorial proposal is to turn those topics into locally testable questions supported by user trials and current technical review. Completing a checklist does not by itself demonstrate that a workstation performs well in every scenario. Findings need to connect to actual tasks and proposed changes.
Console, seating, displays and communications
Adjustment should allow frequent controls to be reached without sustained awkward posture and necessary information to be seen without glare or avoidable repeated movements. Seating, the work surface, input devices and displays form a system: changing one component may move the problem elsewhere. Compatibility between headsets, glasses and comfort throughout the intended use also needs checking.
Solutions require trials with people of different characteristics using the real equipment or a representative reproduction. Space for training or handover matters as much as the space used by the normal position holder. An instructor with insufficient visibility may need to move closer or interrupt, making that configuration worth assessing. No universal screen distance is proposed, and raising volume is not offered as a solution to poor communication. Lighting, intelligibility, layout and maintenance require specific, coordinated evaluation rather than an isolated furniture purchase.
Mental workload, automation and change management
An interface can remove one task while adding another: confirming states, checking discrepancies or retrieving distributed information. Change assessment therefore needs to consider normal work and foreseeable degraded situations, involving controllers, training, engineering and safety specialists. A tool’s modern appearance does not demonstrate that it reduces mental workload.
As an editorial framework, reviewers can examine which information has priority, how a relevant alert is distinguished, which actions require confirmation and how system state is understood. Trials need criteria defined before implementation and must record difficulties as well as preferences. These questions do not authorise unilateral changes to colours, alarms or procedures in an operational system. Any change affecting the service must follow its formal safety, validation and approval process. Occupational prevention and operational safety should communicate without becoming interchangeable, and proposed improvements must be checked for unintended consequences.
Rosters, breaks and fatigue as organisational responsibilities
The European ATM/ANS framework requires providers to manage fatigue and establish a rostering system with safe alternation between duty and rest. Providers must specify elements including consecutive working days, duty duration, time providing control without breaks, rest periods and night work. They must also consult affected controllers or their representatives during the system’s development and application.
Associated guidance proposes comparing planned and actual rosters, changes, extensions and the effectiveness of fatigue reporting. This can reveal a problem hidden by the theoretical schedule. EASA has published a study involving 36 providers and 236 controllers, useful for understanding practices and informing local reviews. It does not calculate a person’s fitness from their age or guarantee that one rotation suits every unit. Reviewing actual implementation is essential: scheduled recovery offers little protection if operational arrangements repeatedly prevent people from taking it.
Managing age without assuming deterioration
Chronological age alone does not describe experience, health, preferences or functional capability. HSE guidance recommends consulting older workers and avoiding assumptions about the jobs they can do. Applied here, the useful questions concern specific difficulties and potentially helpful changes, while maintaining applicable aviation requirements.
Accommodation may involve better adjustments, learning with sufficient practice or reviewing how a function is organised, according to assessment and feasibility. All training should not automatically be assigned to experienced older colleagues, nor should younger colleagues be assumed to master every digital system. Experience becomes useful when made explicit and checked against current procedures. The aim is to support safe performance throughout a working career without informal age-based exclusion or weakened competence criteria. A fair review examines the task and the individual circumstances rather than treating membership of an age group as evidence of a problem.
Generational succession and knowledge transfer
A succession plan can identify knowledge concentrated in a few people, positions requiring endorsements and the actual time needed for learning. Expected departures of experienced staff cannot be addressed by recruitment alone: instructional, supervisory and assessment capacity are also needed. These activities take time and must be included in planning.
A practical editorial proposal is to organise structured sessions on scenarios, justified decisions and coordination, distinguishing official procedures from local habits. Learners need room to question and check; instructors need clear responsibilities and workload limits. Informal mentoring does not replace the training or privileges required to instruct and assess. Succession is ready when there is evidence of competence under the applicable system, not merely when a folder has been shared or an administrative date reached. Capturing knowledge should make it usable and verifiable, rather than simply increasing the volume of documentation.
Aeromedical certification, occupational health and confidentiality
The European regime requires class 3 medical certificates for applicants for and holders of controller or student controller licences, with the specified exception where privileges are exercised in a synthetic training device environment. Assessments and renewals belong to authorised professionals and centres under the applicable rules. Age may influence regulatory intervals but does not replace individual medical assessment.
Aeromedical certification and workplace prevention serve complementary purposes. A valid certificate does not remove the obligation to improve deficient conditions. Nor can a supervisor turn a fatigue complaint into a diagnosis. Clinical information must remain confidential; the organisation receives what is necessary to manage restrictions or accommodations through lawful channels. Records should distinguish professional competence, document validity and medical information, avoiding dashboards that expose clinical histories. The relevant authorised professional, rather than a general productivity score, determines medical conclusions and any necessary follow-up.
A hypothetical redesign and learning example
A centre prepares to replace a console while recruiting staff and anticipating several retirements. During a simulation trial, people of different ages report that some information requires repeated turning and that the instructor’s space makes observation difficult. The team records both findings without attributing them to one generation’s supposed inability to adapt.
The proposed response combines design review, subsequent trials and training scheduled within planned workload. Acceptance criteria and unresolved questions are documented for the formal change process. If a redesign improves reach but increases visual search, adjustment continues before the problem is considered resolved. This is an illustrative scenario, not results from a real centre or evidence that a particular product is certified. It demonstrates why workstation design, learning and organisation need to be assessed together, with clear evidence for each claimed improvement.
Indicators that support decisions
Useful monitoring can record outstanding workstation adjustments, recurring usability problems, breaks actually taken, deviations from planned rosters and time available for instruction. Succession planning needs visibility of competence and function coverage without publishing lists of supposedly dispensable people. Results must be interpreted in the context of traffic, configuration and organisational change.
Eliminating fatigue reports is not a suitable target: reporting could decline without conditions improving. Comparing raw error counts between age groups does not establish causation either. As an editorial proposal, each indicator should have a definition, owner, review interval and associated decision; for example, reviewing a configuration when a problem recurs after training. Closure requires checking the effectiveness of the measure and hearing from workstation users, not simply marking an action complete. Data should help identify conditions that can be improved, rather than create unsupported rankings of individuals.
Frequently asked questions
Does age alone determine a controller’s fitness?
No. Aviation requirements and individual assessment apply; incapacity cannot be inferred from age or an isolated complaint.
Does a medical certificate replace workstation assessment?
No. Certification and prevention of workplace risks have complementary purposes.
Is replacing the chair or displays enough?
No. Tasks, interfaces, communications, rosters and training need assessment together, with verification of the change’s effects.
Does mentoring allow new privileges to be exercised?
No. Knowledge transfer complements but does not replace required training, assessment and authorisations.
