About COMAC Aircraft & Fuel Consumption
COMAC (Commercial Aircraft Corporation of China) develops regional and commercial jets like the ARJ21, C919, and the upcoming CR929. Their fuel consumption is comparable to similar aircraft from Boeing and Airbus:
- ARJ21: Regional jet, ~2,300 L/hr fuel burn, similar to Embraer E-Jets.
- C919: Narrow-body aircraft, ~2,600 L/hr fuel burn, comparable to Airbus A320neo and Boeing 737 MAX.
- CR929: Wide-body jet under development, estimated ~5,600 L/hr, comparable to Airbus A350.
- Fuel Types: Certified for Jet-A/Jet-A1 and expected to adopt sustainable aviation fuels (SAF).
- Efficiency: Newer COMAC aircraft focus on reducing fuel burn and emissions in line with international standards.
Calculation Formulas:
- Fuel Used = Burn Rate (liters/hour) × Flight Hours
- Total Cost = Fuel Used × Fuel Price
- CO₂ Emissions = Fuel Used × Emission Factor (kg CO₂ per liter)
Example:
A COMAC C919 with a burn rate of 2,600 L/hr flying for 2.5 hours using Jet-A fuel at ₹90/liter:
- Fuel Used = 2,600 × 2.5 = 6,500 liters
- Total Cost = 6,500 × 90 = ₹585,000
- CO₂ Emissions = 6,500 × 2.50 = 16,250 kg CO₂
