Pilots rely on precision, skill, and reliable equipment—both in the cockpit and on the ground. While aircraft systems are rigorously maintained, pilots also use portable electrical devices such as laptops, radios, GPS units, tablets, and charging equipment during pre-flight planning, briefings, and navigation.
PAT testing (Portable Appliance Testing) ensures these devices are safe, reliable, and ready for use—helping pilots maintain safety and professionalism in every aspect of their work.
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 cords, damaged plugs, or signs of wear.
- Electrical testing – using specialist devices to detect hidden faults.
After testing, each item is labelled pass/fail, and a certificate is usually issued. This documentation can be important for insurance, compliance, and professional standards.
Why PAT Testing Matters for Pilots
Even small electrical faults can have serious consequences. PAT testing helps by:
- Protecting the pilot and crew – preventing electric shocks, fires, or damage during pre-flight operations.
- Ensuring reliable equipment – laptops, GPS units, radios, and chargers must work flawlessly for accurate flight planning and communication.
- Maintaining professionalism – demonstrating commitment to safety standards for airlines, flight schools, or charter operations.
- Supporting insurance and compliance – many aviation and workplace policies require proof of safety-checked equipment.
- Minimising downtime – early detection of faults prevents delays or disruptions.
What Equipment Should Pilots Get PAT Tested?
Any portable electrical device used during flight prep or training should be considered:
- Laptops, tablets, and e-flight bags
- Radios, GPS units, and communication devices
- Chargers, adapters, and power banks
- Portable lighting or desk lamps in briefing rooms
- Small appliances used in simulators or flight prep areas
Even devices that seem minor can pose a risk if faulty, so comprehensive checks are essential.
How Often Should PAT Testing Be Done?
The frequency depends on usage:
- Annually – for devices used daily or frequently moved between locations.
- Every 2 years – for low-use or stationary equipment.
- After damage or repair – always retest before use.
Most pilots and flight schools follow an annual PAT schedule for all portable devices to maintain safety and reliability.
Is PAT Testing a Legal Requirement?
PAT testing itself is not directly mandated by law. However, UK and European regulations require that all electrical equipment used at work be safe. PAT testing is the recognised method to demonstrate compliance and is often expected by airlines, flight schools, or insurance providers.
Final Thoughts
For pilots, safety is everything—both in the air and on the ground. PAT testing ensures that the portable electrical devices supporting your work are safe, reliable, and professional, allowing you to focus on flying with confidence.
Because the only sparks in your operation should come from your expertise—not faulty electrical equipment.
