| Wingspan | 199 ft 11 in (60.9 m) | 236 ft 2 in (72.0 m) |
| Maximum Takeoff Weight | 775,000 lbs (351,534 kg) | 803,000 lbs (364,235 kg) |
| Passenger Capacity | 368-451 (depending on configuration) | 300-410 (depending on configuration) |
| Range | 6,014 nautical miles (11,750 km) | 8,000 nautical miles (14,800 km) |
At first glance, the Boeing 777-300ER boasts a longer fuselage and a slightly smaller wingspan compared to the A350-900. However, the A350-900 edges out in terms of maximum takeoff weight and range, making it a formidable contender for airlines looking to cover vast distances efficiently.
Performance and Efficiency
Now, let’s talk performance. The Boeing 777-300ER is powered by the GE90 engines, which are among the most powerful in the world. These engines provide exceptional thrust and reliability, but they also come with a hefty appetite for fuel.
On the other hand, the Airbus A350-900 is equipped with Rolls-Royce Trent XWB engines, designed for maximum efficiency. The A350’s composite materials contribute to a lighter airframe, which translates to lower fuel consumption.
Fuel Efficiency Comparison
Fuel efficiency is a critical factor for airlines, and here’s how they stack up:
| Aircraft | Fuel Burn per Seat (Approx.) |
|---|---|
| Boeing 777-300ER | 3.1 liters per 100 km |
| Airbus A350-900 | 2.9 liters per 100 km |
The A350-900 takes the lead here, offering airlines a better fuel burn per seat, which is crucial for profitability on long-haul routes.
Passenger Experience
When it comes to passenger comfort, both aircraft have their merits. The Boeing 777-300ER has a reputation for spacious cabins and large windows, allowing for a more pleasant flying experience. However, the A350-900 takes this a step further with its quieter cabin and advanced air quality systems, which help reduce fatigue on long flights.
Cabin Layout
Let’s break down the cabin configurations:
