Introduction

When it comes to regional turboprop aircraft, the ATR72 and Q400 are two popular choices for airlines around the world. Both aircraft offer efficient and reliable performance for short-haul flights, but they also have their own unique attributes that set them apart from each other. In this article, we will compare the key features of the ATR72 and Q400 to help you understand the differences between these two aircraft.

Performance

The ATR72 is powered by two Pratt & Whitney Canada PW100 engines, while the Q400 is equipped with two Pratt & Whitney Canada PW150A engines. The Q400 has a higher maximum cruise speed of 360 knots compared to the ATR72's 317 knots. Additionally, the Q400 has a longer range of 1,360 nautical miles, while the ATR72 has a range of 1,000 nautical miles. However, the ATR72 has a higher payload capacity of 7,500 kg compared to the Q400's 6,000 kg.

Cabin Comfort

Both the ATR72 and Q400 offer comfortable cabins for passengers, with spacious seating arrangements and overhead storage bins for carry-on luggage. The ATR72 has a typical seating capacity of 68-78 passengers, while the Q400 can accommodate 68-90 passengers. The Q400 has larger windows and overhead bins compared to the ATR72, providing a more open and airy feel in the cabin. However, the ATR72 has a lower cabin noise level, making it a quieter ride for passengers.

Operating Costs

When it comes to operating costs, the ATR72 is known for its fuel efficiency and lower maintenance costs compared to the Q400. The ATR72 has a lower fuel burn rate of 1,100 kg per hour, while the Q400 burns around 1,300 kg per hour. Additionally, the ATR72 has longer maintenance intervals, reducing downtime and maintenance costs for airlines. However, the Q400 has a higher resale value compared to the ATR72, making it a more attractive option for airlines looking to upgrade their fleet in the future.

Runway Performance

Both the ATR72 and Q400 are capable of operating on short runways, making them ideal for regional airports with limited infrastructure. The ATR72 has a takeoff distance of 1,165 meters, while the Q400 requires a slightly longer takeoff distance of 1,463 meters. However, the Q400 has a shorter landing distance of 1,170 meters compared to the ATR72's 1,280 meters. This makes the Q400 more versatile for airports with challenging runway conditions.

Technology and Avionics

Both the ATR72 and Q400 are equipped with modern avionics systems to enhance safety and efficiency during flight. The ATR72 features a glass cockpit with digital displays, while the Q400 has a similar cockpit layout with advanced flight management systems. The Q400 also has a more advanced autopilot system compared to the ATR72, allowing for smoother and more precise flight operations. Overall, both aircraft are equipped with state-of-the-art technology to ensure a safe and comfortable flying experience for passengers.

Conclusion

In conclusion, the ATR72 and Q400 are both reliable and efficient regional turboprop aircraft that offer unique features and capabilities. The ATR72 is known for its fuel efficiency and lower operating costs, while the Q400 offers higher performance and versatility in terms of runway operations. Ultimately, the choice between the ATR72 and Q400 will depend on the specific needs and priorities of the airline, whether it be cost-effectiveness, performance, or passenger comfort. Both aircraft have proven to be popular choices for airlines around the world, serving as workhorses for regional air travel.
