What to look for
Count the engines
The A330 has two large under-wing engines. Every A340 has four smaller engines, two beneath each wing.
Landing gear
A340 variants carry an additional centreline landing-gear unit. The A330 uses its nose gear and two main wing-mounted bogies.
Do not use the cockpit
Their noses and cockpit windows are deliberately similar. Confirm the engine count before trying to judge fuselage length or wingtip details.
Make it stick
Can you identify them without the labels?
