Aircraft comparison
The McDonnell Douglas MD-11 carries 2.1 times as many passengers as the Boeing 727 (323 vs 155).
The McDonnell Douglas MD-11 flies 7,732 km farther non-stop than the Boeing 727. That difference is like a Madrid–Bogotá flight.
At take-off, one McDonnell Douglas MD-11 can weigh as much as 3 Boeing 727 aircraft combined.
Over 1,000 km of cruise, the McDonnell Douglas MD-11 arrives 2 minutes ahead of the Boeing 727.
The Boeing 727 first flew 27 years before the McDonnell Douglas MD-11.
About 1,832 units of the Boeing 727 were built: 9.2 times as many as the McDonnell Douglas MD-11.
Nose to tail, the McDonnell Douglas MD-11 is 14.9 m longer than the Boeing 727.
Parked side by side at the same scale: each drawing is as wide as the aircraft is long (the chosen variant or, when the model is chosen, its representative variant).



Each bar is measured against the largest in the comparison; the crown marks the leader.
Each shaded area is what it could reach non-stop from the chosen city. Filled dots are cities within reach of at least one.
Nominal range with a typical passenger load, measured in a straight line over the sphere (great-circle route). In practice every flight follows airways, carries fuel reserves and depends on wind, payload and runway.
From each model's first flight to the end of its production.
Figures for each variant (and, when the model is chosen, for its most representative variant), taken from manufacturers' published specifications and standard aviation references: every configuration changes them somewhat. A specific aircraft takes its variant's figures when its designation identifies it unambiguously, plus the data in its own record.
