Lightning Induced Transient Susceptibility (LITS) testing is one of the most critical evaluation processes for ensuring the safety and reliability of electronic systems used in aviation, defense, and naval platforms. These tests verify the resilience of equipment against electromagnetic transients induced on cable bundles when exposed to lightning-generated electromagnetic fields.
At Consept EMC Laboratory, we made a major investment in this field back in 2008, becoming one of the first laboratories in Türkiye accredited to perform LITS testing according to RTCA DO‑160 and MIL‑STD‑461 standards. This early investment laid the foundation for the advanced technical expertise we maintain today.
⚙️ What Is Lightning Induced Transient Susceptibility?
LITS testing evaluates how equipment responds to transient voltages and currents induced on cables when lightning strikes nearby structures or aircraft surfaces. These induced transients can:
Propagate along cable bundles
Couple into power and signal lines
Cause system malfunctions, resets, or permanent damage
For this reason, LITS is considered a mandatory safety test for mission‑critical systems.
🛠️ Which Systems Require LITS Testing?
Lightning Induced Transient Susceptibility requirements apply to:
All interconnecting cables of safety‑critical equipment
Complete power cable assemblies
High‑side power cables tested individually
Cables and electrical interfaces of non‑critical equipment connected to critical systems
Additionally, procurement authorities may require LITS testing for non‑critical equipment when system‑level safety considerations demand it.
🚢 Applicability to Naval Platforms
These requirements are not limited to aviation.
LITS testing also applies—under specific conditions—to surface ship equipment with topside cable routing, extending its relevance to both military and civilian maritime applications.
🔧 More Than Just a Power Test: The Technical Importance
Lightning Induced Transient Susceptibility testing validates far more than power line robustness. It ensures:
System durability under extreme electromagnetic stress
Continuity of critical functions
Compliance with EMI/EMC requirements
Alignment with safety and certification standards
For modern aerospace and defense electronics, LITS is an indispensable certification step that directly impacts operational safety and mission reliability.
