Why can’t a plane land with full fuel?

Planes are designed to land below certain weights. A heavier plane is more likely to hit the ground hard and get damaged. It’s got 5,000 gallons of fuel, which is about three elephants weighing it down. So, landing with a full tank is pretty risky.

What octane is jet fuel?

The octane ratings of AVGAS, a gasoline-based fuel, are usually either 91 or 100 (lean mixture) and 96 or 130 (rich mixture). The octane rating of jet fuel is much lower, around 15 – this is much more like automotive diesel and thus much more resistant to detonating due to sparks or compression.

Do planes dump fuel in the ocean?

In order to do so, the aircraft, a Boeing 787-9 with registration G-ZBKO, spent a little over an hour dumping fuel over the North Sea before coming in for a safe landing. So why do airplanes dump fuel? While fuel dumps don’t happen every day, they’re also not uncommon. Nor do they usually represent a major emergency.
