SMS AND VIKING VOYAGES

An Aviation Safety Management System (SMS) provides a structured way to identify hazards, assess risks, introduce controls, and determine whether those controls work. Its purpose is to support sound decisions before harm occurs and improve operations through continuous learning. The Vikings called their SMS “Sail My Seas”. Viking voyages offer a useful historical analogy: crews crossed unfamiliar waters where weather, navigation, vessel condition, supplies, and human judgment could determine survival. Applying SMS principles to those journeys illustrates how leadership and organized learning can strengthen safety. This is a hypothetical comparison, rather than a claim that Vikings operated a formal SMS resembling modern aviation systems.

The Vikings’ extensive voyages demonstrate the importance of managing uncertainty. Norse expansion across the North Atlantic connected distant communities and reached places including Iceland, Greenland, and North America. Such journeys required practical seamanship and adaptation to demanding environments. However, reaching a destination would not necessarily prove that every decision was sound. A vessel could survive despite weaknesses in planning or preparation. Aviation organizations face the same problem when successful flights conceal deteriorating safety margins. SMS encourages leaders to examine how an operation succeeded and whether its success can be repeated safely under different circumstances.

Leadership would be the starting point for a Viking SMS. The expedition leader would establish that protecting people and preserving the vessel were essential responsibilities. Departure decisions would consider readiness alongside commercial ambitions, exploration goals, and seasonal pressures. Crew members would understand their duties, reporting arrangements, and authority to raise concerns. In aviation, executives similarly need to provide resources and support operational decisions consistent with safety objectives. A policy becomes meaningful when leaders accept delays, repairs, or changes to plans because available evidence shows that proceeding would expose people to unacceptable risk.

Hazard identification would begin before departure and continue throughout each voyage. Viking crews could examine damaged planking, worn rigging, unstable cargo, insufficient drinking water, inexperienced sailors, and uncertain landing conditions. They could also identify external hazards such as storms, fog, cold water, rocky shorelines, and limited shelter. The aviation equivalent includes aircraft defects, runway contamination, adverse weather, fatigue, and inadequate operational information. Identifying a hazard does not require an accident. A small leak, confusing instruction, or repeated navigation disagreement can reveal a developing problem while there is still time to intervene.

Risk assessment would help distinguish manageable concerns from conditions requiring immediate action. A weakened sail might create limited difficulty near shelter but become critical during a long ocean crossing. Its significance depends on exposure, available alternatives, and the possible consequences of failure. Viking leaders could compare those factors before choosing to sail, repair, reduce cargo, or change routes. Aviation SMS applies similar reasoning when evaluating hazards within a particular operation. Risk ratings should guide discussion and decisions, while uncertainty, interacting hazards, and the limits of available evidence remain visible to those accepting the risk.

Risk controls would need to match the actual danger. Viking measures could include inspecting hulls and rigging, securing cargo, carrying repair materials, preserving supply reserves, and choosing departure conditions appropriate to the vessel and crew. Assigning experienced sailors to critical duties would provide another protective measure. Aviation uses comparable layers through maintenance, training, operating procedures, weather assessment, and contingency planning. Several controls can strengthen resilience, but their independence matters. Multiple precautions offer little protection when all depend on one exhausted person recognizing the same warning at the same moment.

Human factors would deserve particular attention. Cold, hunger, fatigue, fear, and social pressure could reduce a sailor’s ability to observe conditions and make sound decisions. A respected leader might unintentionally discourage disagreement, especially if hesitation appeared inconsistent with courage. An SMS approach would make speaking up part of competent seamanship. Aviation crews likewise need working conditions that support alertness, communication, and constructive challenge. Courage should include acknowledging uncertainty and requesting assistance. Confidence is useful when supported by competence; it becomes hazardous when authority prevents others from questioning assumptions or reporting deterioration.

Reporting would turn individual observations into shared knowledge. After a voyage, crews could discuss unexpected currents, damaged equipment, supply shortages, navigational uncertainty, and difficult approaches to shore. Successful journeys would also deserve review, particularly when survival depended on improvisation or favourable conditions. Aviation organizations can learn similarly from hazards, incidents, diversions, and other operational experiences. A fair reporting environment encourages honest accounts while retaining accountability for deliberate misconduct. Reports need timely responses and practical follow through, so personnel can see that their information contributes to better decisions and safer working conditions.

Investigation would look beyond the final mistake. If a vessel approached dangerous rocks, asking only who steered would miss potential weaknesses in lookout duties, fatigue management, route knowledge, or leadership instructions. The useful question would be why the crew’s protections failed to detect and correct the danger. Aviation investigations benefit from the same systems perspective. Corrective action should address underlying conditions rather than depend entirely on reminders to be careful. Otherwise, the organization may replace one person while leaving the circumstances that could expose another person to the same failure.

Safety assurance would establish whether improvements worked. Viking leaders could compare recurring defects, supply consumption, injuries, and difficulties reported across successive voyages. They could check whether inspections actually detected damage and whether revised preparations reduced problems. Aviation organizations use monitoring, reviews, and audits to evaluate operational controls. An absence of accidents alone provides limited assurance, especially where activity is infrequent or consequences are rare. Managers need evidence that safeguards function during everyday operations and that corrective actions remain effective after initial attention fades.

Training and knowledge sharing would preserve learning beyond a single crew. Experienced sailors could demonstrate repairs, explain warning signs, rehearse emergencies, and prepare less experienced members for demanding duties. Oral teaching and practical demonstration could serve this purpose without assuming modern documentation existed. Aviation adds controlled procedures, records, and formal instruction, but the objective remains transferable understanding. Personnel should know why precautions matter and how to respond when circumstances change, rather than simply memorize instructions.

Change would require renewed assessment. A different vessel, unfamiliar route, heavier cargo, or inexperienced crew could invalidate assumptions drawn from earlier voyages. Modern aviation faces comparable changes in equipment, staffing, destinations, and schedules. Before proceeding, leaders should examine new hazards, confirm resources, and decide whether existing controls remain adequate.

Emergency preparation would also matter. Crews could assign responsibilities for taking in water, losing steering control, or seeking shelter. Aviation organizations similarly need coordinated responses to foreseeable emergencies, supported by practice and clear communication. Preparation improves the ability to respond effectively when prevention proves insufficient.

The central lesson is that achievement and safety require continuing human judgment. SMS could have helped Viking voyagers organize experience, challenge risky assumptions, and protect future expeditions. For aviation leaders, its value lies in making hazards visible, supporting responsible decisions, and verifying that protections work. Technology can assist this process, but people must remain accountable for understanding conditions and acting before preventable harm occurs.

Viking voyagers can be understood as practising an early, informal equivalent of an SMS (Sail My Seas) by sharing their experiences with others preparing to sail. Knowledge about dangerous waters, changing weather, ship weaknesses, crew fatigue, and unfamiliar destinations could help the next crew recognize hazards and make better decisions. Sharing both successful practices and mistakes turned individual experience into collective learning. Although this was not a formal SMS in today’s sense, it illustrates an enduring safety principle: lessons from one voyage can help protect those setting out on the next.
