Boeing 737NG

Field marks

  1. The engine nacelle is sliced flat on the bottom — the classic 737 tell, needed for ground clearance on its low-slung gear
  2. Angular cockpit windows with a sharp notch where the side window meets the windshield, unlike any Airbus
  3. A blended winglet (single upturned blade) is the default; a split scimitar (blade plus small downward fin) marks a retrofit, and plain tips mark an early, unmodified aircraft

Variant notes

  • One entry spans the -700 (33.6 m), -800 (39.5 m), and -900/-900ER (42.1 m) — the -800 is by far the most common
  • Blended winglets are standard on most in-service aircraft; many carriers (Southwest, Ryanair, United) have retrofitted split scimitar tips
  • The world’s single most numerous narrowbody family currently flying
