- A330neo: 7,200 nautical miles (13,334 km)
- A350 cruising speed: Mach 0.85
- A330neo cruising speed: Mach 0.82
Fuel Efficiency and Cost
The economic comparison between these aircraft reveals interesting trade-offs:
| Aspect | A350-900 | A330-900neo |
|---|---|---|
| Acquisition Cost | $317 million | $260 million |
| Fuel Efficiency | 25% better than original A330 | 14% better than original A330 |
Passenger Capacity and Comfort
| Feature | A350 | A330-900neo |
|---|---|---|
| Passenger Capacity (3-class) | 300-350 (A350-900) Up to 410 (A350-1000) |
260-300 |
| Cabin Width | 5.96m | 5.64m |
| Economy Seat Width | 18 inches | 17.5 inches |
The A350’s cabin experience sets new standards in passenger comfort with several key advantages:
- Larger windows for better views and natural light
- Higher cabin humidity (16% vs 5-10% in older aircraft)
- Lower cabin altitude pressurization (6,000 feet vs 8,000 feet)
- Approximately 6 decibels quieter operation than the A330
- More spacious aisles and improved overhead bin design
While the A330neo has incorporated some A350-inspired features like updated lighting systems, its fundamental cabin architecture reflects its earlier generation design. These comfort differences have notably influenced premium carriers, who often select the A350 for flagship long-haul routes where passenger experience is paramount.
Design and Material Composition
The A350 represents a revolutionary shift in aircraft construction, with 50% of its structure utilizing advanced composites. This modern approach contrasts sharply with the A330neo’s traditional aluminum construction, resulting in significant weight reduction while maintaining structural integrity.
| Material | A350 Composition | Purpose |
|---|---|---|
| Advanced Composites | 50% | Weight reduction, structural strength |
| Titanium | 14% | High-stress areas |
| Aluminum/Aluminum-lithium | 19% | Strategic reinforcement |
| Steel | 6% | Critical structural components |
Aerodynamic Features
The A350’s advanced aerodynamic design features distinctive saber-like wings with upward curves in the final 14 feet, replacing traditional wingtip fences found on the A330. With a more aggressive 31.9-degree sweep angle, the A350 achieves a maximum cruising speed of Mach 0.89, compared to the A330’s Mach 0.86.
- 25% lower overall drag compared to previous generation aircraft
- Optimized surface transitions for improved airflow
- Enhanced takeoff performance and cruise efficiency
- Improved landing characteristics
- Smoother contours throughout the fuselage
Material Use and Efficiency
The A350’s revolutionary material composition delivers substantial benefits:
- 20% weight reduction compared to traditional aluminum construction
- Enhanced resistance to fatigue and corrosion
- Reduced expansion and contraction during pressure cycles
- 25% reduction in fuel consumption
- Extended maintenance intervals
- Improved residual values
