Embraer E170
The Embraer E170 is a twin-engine regional jet that forms part of the highly successful E-Jet family developed by the Brazilian aerospace manufacturer Embraer. Introduced in 2004, the E170 was designed to cater to the growing demand for efficient, short- to medium-haul regional air travel. With a seating capacity ranging from 66 to 78 passengers, the aircraft provides a comfortable flying experience while maintaining operational efficiency for airlines.
The E170 is a significant evolution from Embraer’s ERJ 145 series, featuring a wider fuselage, advanced avionics, and more efficient engines. It was the first of the E-Jet series to enter service, setting the foundation for its larger counterparts, the E175, E190, and E195. Airlines have embraced the E170 for its low operating costs, superior range, and passenger comfort, making it a staple for regional operations worldwide.
Cargo Hold and Cabin Design
While primarily a passenger aircraft, the E170 offers substantial cargo capacity, making it a versatile option for regional carriers that need both passenger and freight services. The aircraft features:
- Underfloor cargo compartments, providing space for baggage and light cargo.
- Total cargo volume of approximately 12.7 cubic meters (448 cubic feet).
- Optional configurations that allow for increased cargo storage with optimised weight distribution.
Inside the cabin, the E170 features a 2-2 seating configuration, eliminating the middle seat and enhancing passenger comfort. The cabin width of 2.74 meters (9 feet) provides ample space, ensuring legroom and aisle accessibility comparable to larger mainline jets.
Technology: Engine and Avionics
The E170 is powered by two General Electric CF34-8E turbofan engines, each producing 14,200 lbf (63 kN) of thrust. These engines are designed for high fuel efficiency and lower emissions, making the aircraft an eco-friendly choice for airlines.
The aircraft’s key technological features include Full Authority Digital Engine Control (FADEC) that enhances engine performance and fuel efficiency; Honeywell Primus Epic Avionics Suite, a state-of-the-art integrated flight deck that includes: Five large LCD screens for flight data; autothrottle and dual Flight Management System (FMS) for enhanced automation; weather radar and terrain awareness to improve safety, and Fly-by-Wire System to reduce pilot workload and enhances flight stability.
Performance
The aircraft has been designed to maximise operational flexibility by offering superior range and fuel efficiency while being able to operate from shorter runways. Its range of 3,889 km (2,100 nautical miles) makes it ideal for short- to medium-haul routes; while maximum cruise speed of Mach 0.82 (870 km/h or 541 mph), allows for rapid turnaround times on high-frequency routes.
The aircraft’s take-off distance of1,261 meters (4,140 feet) enables it to serve airports with shorter runways, and the landing distance of 1,260 meters (4,133 feet), allows it easy access to regional airports.
The wing design features high-performance winglets, reducing drag and enhancing fuel efficiency, which helps airlines cut operational costs while maintaining reliability.
