Why Cybersecurity Matters in MID MI-005 Certification for Aviation Fueling and Packaging

Bringing precision and protection to MI-005 fuel transfer and packaging—wherever you operate 

As aviation fuel transfer operations scale and digitalisation accelerates on the runway, the demand for accurate, compliant, and cyber-resilient measurement has never been higher. At NMi, we’re meeting that demand head-on—with a strengthened approach to MID MI-005 (Module B + F) certification and cybersecurity assurance for aviation fuel measuring systems. 

From aircraft refuelers to packaging lines, we help you protect what matters: measurement integrity, operational continuity, and market trust. 

What MI-005 brings to aviation fueling and packaging 

MI-005 applies to measuring systems for liquids other than water, including aviation fuel and a wide range of packaged liquids. NMi is there across the full conformity path:

• Module B – Type approval: Verifies that your design meets MI-005 requirements for performance, accuracy, stability, compatibility, and safety—now with an explicit focus on digital interfaces and data integrity.
• Module F – Product verification: Confirms that manufactured units conform to the approved type, including software/firmware versions, sealing, and metrological performance under real operating conditions.

For operators and manufacturers, this is the foundation for trusted transactions, regulatory compliance, and long–term performance—on the runway or on the line. 

Why Cybersecurity now sits alongside accuracy 

Modern fuel and packaging systems are no longer purely mechanical. They rely on controls, sensors, and data paths that can be misconfigured or, in rare cases, targeted.  

What that looks like in practice: 

• Data integrity from source to record: Securing meter signals, totals, and transaction logs against tampering or loss
• Software and firmware governance: Version control, trusted updates, and verification aligned with the approved type
• Access control and roles: Clear separation of duties for calibration, operations, and maintenance—reducing the risk of unintended changes
• Sealing and event trails: Physical and digital seals with audit trails for investigations and product verification
• Secure communications: Hardening of wired/wireless links used for authorisation, pricing, or remote monitoring

The result: measured values you can stand behind, supported by a defensible security posture. 

A step forward for secure, global operations

Demand for MI-005 support is growing across regions and industries. Our combined legal metrology expertise and cybersecurity capability helps you:

• Accelerate compliance for new builds and retrofits. 
• Reduce non-conformities before they impact schedules or deliveries. 
• Demonstrate due diligence to airlines, integrators, and authorities with confidence.

Whether you’re bringing a new fuel system to market or tightening controls on existing assets, we bring the right expertise.
