Specifications for all nine aircraft types in Great Circle Pro — used directly in range circle generation, flight time estimation, fuel burn, and CO₂ calculations. All figures are manufacturer-published values at typical operating weights.

Ranges are manufacturer-published maximums at typical operating weights. Fuel burn figures are cruise averages used in Great Circle Pro calculations and vary with load factor, altitude, and atmospheric conditions. TAS = True Airspeed at cruise altitude.
The workhorse of short to medium-haul airline networks. CFM LEAP-1B engines deliver ~14% better fuel efficiency than the prior 737NG. At 3,550 nm, covers most intra-continental routes and select trans-Atlantic segments from the US East Coast. ETOPS-180 certified.
The best-selling commercial aircraft in history. Powered by either the CFM LEAP-1A or Pratt & Whitney PW1100G geared turbofan, delivering ~20% better fuel efficiency than the A320ceo. Dominant on European intra-continental and medium-haul routes worldwide.
A category-defining aircraft. The XLR (Extra Long Range) variant of the A321 uses a rear-centre fuel tank to reach 4,700 nm — enabling true trans-Atlantic operations from the US East Coast to Western Europe on a single-aisle aircraft, opening city-pair routes previously requiring a widebody.
Boeing's composite-bodied mid-size widebody. At 7,635 nm and Mach 0.85 cruise (~488 kt TAS), the 787-9 covers virtually all trans-Pacific and trans-Atlantic routes with substantial payload. ETOPS-330 certified — among the highest ratings of any commercial aircraft.
Airbus's flagship ultra-long-range widebody, built with 70% composite materials. ETOPS-370 certified — the highest rating in commercial service. Operates some of the world's longest non-stop routes including Singapore–New York (JFK) and Sydney–Dallas, both exceeding 8,000 nm.
The longest-range production aircraft in history. Powered by the GE9X-105B1A — the largest turbofan engine ever built with a 134-inch fan diameter — the 777-9 carries up to 426 passengers over 9,350 nm. Its folding wingtips allow access to standard gates despite a 235-foot wingspan.
The re-engined A330 delivers 787-level fuel efficiency in a proven airframe. At 7,700 nm it covers most long-haul routes, bridging the gap between narrowbody and ultra-long-range widebody operations. A common ETOPS-180 operator with lower capital cost than the A350 or 787.
The benchmark twin-turboprop for regional charter, air ambulance, and government operations. At 272 kt and 1,580 nm, it operates where jet economics don't make sense. Included in Great Circle Pro to show the stark contrast in range envelopes between turboprop and jet operations.
The most produced aircraft in history with over 44,000 built. Included in Great Circle Pro not as a practical planning tool but as a reference point — its 640 nm range circle illustrates the extraordinary scale difference between general aviation and commercial jet operations from any airport on Earth.
