Aviation is very good at recognising visible failure
When a system goes offline, a display goes blank or a service becomes unavailable, the problem is visible. There is usually a clear operational trigger: something has failed and action is required.
The more difficult scenario is when the technology continues to operate.
The display is populated.
The data is flowing.
The system is available.
But confidence in the information itself becomes uncertain.
Availability and trust are not the same thing
System availability answers an important question: is the capability accessible and operating?
It does not necessarily answer another: can the information being presented be relied upon?
As aviation becomes increasingly digital, interconnected and data-dependent, information may be generated, exchanged, processed and presented through several technologies before it informs an operational decision.
That makes information trust an increasingly important part of the resilience conversation.
The difficult scenario is not always a blank screen
Visible failure provides a trigger. It tells the operator that normal conditions have changed.
A more difficult situation can arise when a system remains available but confidence in the information becomes uncertain.
What indicates that something may be wrong?
How are conflicting or unexpected information recognised?
What should an operator rely on while that uncertainty is being resolved?
And at what point does an information-quality concern become an operational concern?
These are not purely technical questions. They sit at the intersection of technology, operations, human judgement and organisational decision-making.
SYSTEM AVAILABLE ≠ INFORMATION TRUSTED
Is the capability operating?
is not necessarily the same question as:
Can the information be relied upon?
More information does not automatically mean more certainty
Digitalisation gives aviation access to richer information, greater connectivity and new opportunities for operational awareness.
But as the number of information sources increases, understanding their reliability becomes increasingly important.
Where information from different sources agrees, confidence may be strengthened. Where it does not, human judgement and operational processes become important in determining what can be relied upon.
The question is therefore not whether aviation should become more connected. It is whether our understanding of resilience is evolving alongside that connectivity and growing dependence on data.
Resilience includes the ability to question what appears normal
Not every resilience challenge announces itself through a blank screen, an outage or a dramatic loss of service.
Sometimes nothing looks wrong.
That is precisely why information trust deserves greater attention within discussions about aviation resilience.
This is not an argument against technology or digitalisation. It is an argument for recognising that continued operation should not automatically be treated as proof that every piece of information being presented is reliable.
Practitioner perspectives
VLM Aviation Infrastructure Advisory is inviting aviation professionals to contribute their perspectives on information trust in operational environments.
1. Which part of the aviation ecosystem best describes your experience?
ANSP / Airport / Airline / Regulator / Engineering or technology provider / Safety or cybersecurity / Research or academia / Other
2. In your operational environment, what gives you confidence that information from a system can be trusted?
3. Have you encountered a situation where a system remained operational but the reliability or consistency of the information was questioned?
Yes / No / Prefer not to say
If appropriate, you may provide a brief description without identifying an organisation or sharing sensitive information.
4. When information from different systems or sources conflicts, what is the greatest practical challenge in determining what to trust?
5. What question about information trust and aviation resilience deserves greater industry attention?
Please do not submit classified, security-sensitive, proprietary or organisation-identifying operational information. Contributions are intended to capture professional perspectives and experience at a general level.
One question to leave with the industry
When everything appears to be working, what gives you confidence that the information can be trusted?
