Insights, Tips, and Guides for Aviation Professionals

Think about what it takes for a flight to happen. Before any aircraft leaves the ground, someone has inspected the engine, checked the fuel, cleared the ramp, and briefed the crew. General aviation runs on the work of pilots, mechanics, fuelers, and ground crews, and those people face real hazards every day.

Maintenance-related human factors account for a significant share of aviation accidents across all operational sectors. Safety data consistently shows that many human-error events originate in maintenance rather than the flight deck, following recurring patterns across aircraft types and operators.

Aircraft batteries are a core part of your aircraft’s electrical system. They power engine starts, support onboard systems, and act as a backup when it matters most. Over time, even high-quality batteries lose their ability to hold charge and deliver consistent performance. Knowing when and how to replace your aircraft battery helps avoid delays, inspection issues, and unexpected failures.

This is a straightforward guide backed by real products from National Aviation to help you choose the right oil. Unlike automotive engine oil, aviation oil must perform under extreme temperature swings, from a cold hangar start at -20° F to operating temperatures that can exceed 240° F, at altitudes where atmospheric pressure drops significantly. It must resist oxidation, prevent corrosion from moisture and combustion acids, suspend lead by-products from avgas, and maintain stable viscosity from the first second of engine start.
