About ATR Aircraft & Fuel Consumption
ATR aircraft are regional turboprop airliners, widely used for short-haul flights due to their efficiency. The ATR 42 and ATR 72 families are among the most fuel-efficient aircraft in their class.
Factors Influencing Fuel Consumption:
- Model: Larger variants like the ATR 72 consume more fuel than the smaller ATR 42.
- Payload & Passengers: Heavier loads increase fuel burn.
- Flight Distance: Shorter flights can have higher per-hour fuel usage due to more takeoff/climb phases.
- Operational Conditions: Hot/high-altitude airports reduce efficiency.
- Fuel Type: ATR aircraft typically operate on Jet-A/Jet-A1, with biofuel blends emerging.
Formulas Used:
- Fuel Used = Burn Rate (L/hr) × Flight Hours
- Total Cost = Fuel Used × Price per Liter
- CO₂ Emissions = Fuel Used × Emission Factor (kg CO₂/L)
Example:
An ATR 72-600 flying for 2 hours on Jet-A1 fuel at ₹90/liter:
- Fuel Used = 950 × 2 = 1900 liters
- Total Cost = 1900 × 90 = ₹171,000
- CO₂ Emissions = 1900 × 2.45 = 4655 kg
Note: ATR aircraft are among the most fuel-efficient regional aircraft, but actual consumption depends on payload, weather, and flight profile.
