From Sky to Ground: G-forces, Aerobatics, and the Art of Keeping the Aircraft (and Pilot) in One Piece

Flying isn’t just about moving through the air. Real flying is about pushing the limits of human endurance, engineering design, and decision-making under extreme pressure. No one understands that better than Aarron Deliu.

With over 25 aircraft types under his belt — from silent gliders to high-performance jets and military warbirds — Deliu doesn’t just fly. He masters.But where he truly separates himself is in the world of aerobatics: a domain where physics is ruthless, and precision is everything.

What does +10G feel like?

G-force is the gravitational stress acting on a body.+1G is what we feel walking around.+5G compresses you like a vise.+10G? That’s borderline superhuman.

At +10G, a pilot weighing 80 kg feels like 800. Breathing becomes a conscious effort. Blood drains from the brain. Vision narrows to a tunnel. If you’re not trained, you black out — fast.

Flying at this level requires Olympic-level fitness and split-second awareness. The aircraft may be a machine, but the pilot becomes the limiting factor.

The Aircraft: Let’s take the Extra 330

This plane isn’t built for comfort. There are no screens, no autopilot, no luxury seats. It’s designed to be a razor blade with wings.

• Engine: Lycoming AEIO-580, six-cylinder, 315 horsepower.

• Oil: High-performance lubricants like AeroShell W100 Plus, capable of withstanding extreme temps, pressure, and negative Gs.

• Typical maneuvering speed: 220–250 km/h.

• Airframe: Advanced composites and aircraft-grade aluminum, stressed for +10G and -10G.

• Inverted oil & fuel systems: Because in aerobatics, flying upside down is standard.

Before every flight, the aircraft undergoes a rigorous inspection: control surfaces, linkages, cables, landing gear, fuel lines, pressure systems — everything must be flawless.It’s not just maintenance. It’s ritual.

Maneuvers That Defy Logic

• Snap Roll: The aircraft deliberately stalls one wing and spins violently on its axis.

• Hammerhead Turn: Climbs vertically, runs out of speed, and pivots 180° on its yaw axis.

• Lomcevak: A chaotic-looking tumble in all axes — a controlled, full-body assault on physics.

• Torque Roll: Climbs straight up, then slowly flips backward as engine torque spins the plane mid-air.

Each maneuver requires surgical precision. At these forces and speeds, there’s no room for “almost right.”

And after the airshow… the real work begins

• Every 10 hours of aerobatic flight triggers a full structural inspection.

• Wing tips, fuselage joints, and stress points are checked for fatigue.

• Oil changes are frequent — temps reach over 220°C in tight sequences.

• Spark plugs, injectors, magnetos, and pressure lines are cleaned like surgical tools.

• Every bolt is torqued by hand. One loose bolt in a negative-G maneuver can end it all.

Why does this matter?

Because behind every perfect roll, every precision loop, and every high-G inverted turn is a combination of discipline, engineering, and nerve.You may see the pilot. You may hear the engine.But what you don’t see is what really counts: the aircraft systems holding together under stress, the fuel mix staying stable in negative flight, the oil circulating properly while the aircraft is tumbling, and the team ensuring it all works perfectly — every time.
