Hey everyone,
Feel free to share your thoughts below!
1. Cruise Fuel Consumption & Altitude Stability
Airbus A350-900(A359)
Built with composite materials, it delivers outstanding fuel efficiency, a huge advantage for long-distance travel.
Stable at Mach 0.85–0.88 during the whole cruise phase. Even with full passenger loads, it retains generous fuel reserves, so you never need to worry about range limits on 5400km routes.
The autopilot holds altitude firmly. It barely drifts under turbulence or crosswinds aloft, requiring almost no manual adjustments during long auto-cruise segments.
Boeing 777-300ER (B77W)
It can carry far more passengers and cargo, yet it burns significantly more fuel.
If loaded with full passengers and baggage, you have to calculate fuel precisely before departure; higher cruise speeds will drain fuel reserves rapidly.
Its large fuselage tends to wobble slightly when encountering upper-atmosphere turbulence. The autopilot will occasionally drift off target altitude, requiring frequent minor tweaks.
2. Takeoff & Climb Performance
A359
Lighter overall with snappy engine response, rotation is smooth and gentle.
It performs well on regular runways at RCTP Taoyuan, with a short takeoff roll.
Climb rate stays consistent all the way to cruise altitude, with no frequent thrust adjustments needed — very beginner-friendly.
B77W
Classified as a HEAVY aircraft, it demands a much longer takeoff roll.
Climb performance degrades noticeably above medium altitudes, so you have to climb in staged steps instead of a single continuous ascent.
It feels heavy and cumbersome throughout taxi and takeoff, fully showcasing the characteristics of a large heavy airliner.
Final Verdict
Pick the A359 if you want low fuel burn, simple handling, and a relaxing long-haul experience.
Pick the B777-300ER if you want a realistic heavy wide-body simulation and authentic full-load commercial flight operations.
