Pilots rely on a wide range of electrical equipment both in the cockpit and on the ground. From flight instruments, avionics, and communication devices to laptops, chargers, and portable power tools, the safety and reliability of your equipment is critical.
PAT testing (Portable Appliance Testing) ensures all electrical devices are safe, reliable, and compliant, helping pilots focus on flying safely rather than worrying about faulty gear.
What Is PAT Testing?
PAT testing is the process of checking electrical appliances to make sure they are safe to use. It involves:
- Visual inspection – checking for frayed cables, damaged plugs, or visible wear.
- Electrical testing – using specialist tools to detect hidden faults that could cause shocks, fires, or equipment failure.
Each item is labelled pass/fail, and a certificate is issued. For pilots, PAT testing is a practical step in maintaining a professional, hazard-free workspace both in the cockpit and during ground operations.
Why PAT Testing Matters for Pilots
Even minor faults can cause serious safety or operational issues. PAT testing helps by:
- Protecting pilots and crew – preventing electric shocks or fires from faulty devices.
- Ensuring uninterrupted operations – avoiding failures with communication or navigation equipment.
- Maintaining professional standards – demonstrating responsibility and adherence to safety protocols.
- Supporting insurance and regulatory compliance – many aviation authorities and insurers require safe, tested equipment.
- Extending equipment lifespan – catching faults early prevents damage to expensive avionics or electronics.
What Equipment Should Pilots Get PAT Tested?
Any electrical device used in the cockpit, at home, or on the ground should be included:
- Laptops, tablets, and flight planning devices
- Radios, headsets, and communication systems
- GPS units, portable navigation devices, and monitors
- Extension leads, adapters, and chargers
- Small appliances used in offices or pilot lounges (lamps, fans, heaters)
Even portable or occasionally used devices should be tested to prevent hazards.
How Often Should PAT Testing Be Done?
Frequency depends on usage:
- Annually – for frequently used, portable devices.
- Every 2 years – for stationary or low-use equipment.
- After visible damage or repairs – always retest before use.
Many pilots schedule PAT testing annually or before major trips to ensure all essential gear is safe and operational.
Is PAT Testing a Legal Requirement?
PAT testing itself is not explicitly required by law, but UK and European regulations mandate that all electrical equipment used at work must be safe. PAT testing is the recognised method to demonstrate compliance and is often requested by insurers or aviation authorities.
Final Thoughts
As a pilot, your focus should be on flight safety, navigation, and communication—not worrying about faulty electrical devices. PAT testing ensures that all your gear, both in the cockpit and on the ground, is safe, reliable, and professional, letting you operate with confidence.
Because the only sparks in the cockpit should come from engines and instruments—not electrical hazards.
