Wake turbulence categories

Wake categories (Light, Medium, Heavy, Jumbo/A380) drive separation on approach — controllers keep extra space behind heavy aircraft because of the vortices they shed.

Tricks for telling lookalikes apart

  • 737-800 vs MAX 8: MAX has split winglets (chevron) and distinctive chevron engine nacelles
  • A320ceo vs neo: neo has sharklets (smooth curve) and larger engines. "ceo" = current engine option, "neo" = new engine option
  • 777F vs 77W: freighter has no passenger windows
