Comparing Regional Workhorses: ATR 72 ATR 42 and Dash Q400 Differences
Introduction
Regional turboprop aircraft like the ATR 72 ATR 42 and Dash Q400 differences are essential for short-haul routes and smaller airports. Choosing the right aircraft is crucial for operational efficiency and passenger satisfaction. This article compares these three popular models to help airlines make an informed decision.
Aircraft Overview
The ATR 72 and ATR 42 are manufactured by ATR, a joint venture between Airbus and Leonardo. The ATR 72, introduced in 1988, and the ATR 42, first flown in 1984, are known for their reliability and efficiency in regional markets which is a key ATR 72 ATR 42 and Dash Q400 Differences. The Dash Q400, developed by Bombardier, entered service in 2000 and is renowned for its speed and comfort.
Technical Specifications
| Specification | ATR 72 | ATR 42 | Dash Q400 |
|---|---|---|---|
| Capacity (Seats) | 68-78 | 40-50 | 70-78 |
| Range (Nautical Miles) | 825 | 800 | 1,100 |
| Cruise Speed (Knots) | 275 | 275 | 360 |
The ATR 72 and ATR 42 offer similar performance, with the main difference being capacity. The Dash Q400, however, provides a longer range and higher cruise speed, making it suitable for slightly longer regional routes.
Performance and Efficiency
Fuel efficiency and operating costs are critical for regional airlines. The ATR aircraft are known for their excellent fuel economy, particularly on shorter routes. ATR 72 ATR 42 and Dash Q400 Differences slightly less fuel-efficient, compensates with higher speed and longer range.
- Short Takeoff and Landing (STOL) capabilities: All three aircraft can operate on short runways, making them versatile for regional airports.
- Fuel consumption rates: ATR models are generally more fuel-efficient.
- Maintenance costs: All models have competitive maintenance costs, though ATR aircraft may have a slight edge due to simpler systems.
Passenger Comfort and Amenities
Passenger comfort is a key consideration for airlines.
| Feature | ATR 72 | ATR 42 | Dash Q400 |
|---|---|---|---|
| Seat Pitch (Inches) | 30-32 | 30-32 | 32-34 |
| In-Flight Entertainment | Optional | Optional | Available |
| Noise Levels | Low | Low | Very Low |
The Dash Q400 offers superior noise reduction, enhancing passenger comfort. Both ATR models provide a competitive seating arrangement and optional in-flight entertainment.
Operational Versatility
These aircraft are highly versatile, suitable for various regional operations.
- Ability to operate on short runways: All models excel in this area.
- Performance in hot and high-altitude airports: The Dash Q400 has a slight advantage due to its powerful engines.
