Specifications

Range

The Extra Range (XR) can carry a full load of passengers up to 2,000 nm (3,057 km).  See how far the 50-seat ERJ can fly by choosing a city near you.

Cockpit

The Honeywell Primus 1000 fully-digital all-glass avionics suite features five 8 x 7 inch screens driven by dual integrated computers.

The suite has two PFDs, two MFDs, and one EICAS, plus Primus II radios, TCAS, FMS and EGPWS.

All ERJs have a Central Maintenance Computer (CMC) for real-time condition monitoring and automatic fault-finding.

Pilots appreciate the dark and quiet cockpit design philosophy that maximizes ergonomic benefits and safety and minimizes workload.

Airframe

The regional airline operating environment is demanding. High daily utilization. Frequent take offs and landings. Quick ground turnarounds.

The ERJ 145 airframe was developed specifically for regional applications. It wasn't stretched or shrunken from a design meant for another application. It's an optimized family of regional jets, from top to bottom.

Extensive chemical milling, the absence of bonds on metal joints, the use of semi-monocoque composites on secondary structures and the application of a special protection coating all contribute to the airframe's strength.

That durability is reflected in the ERJ's 75,000 flight hour or 60,000 cycle crack-free design life.

Commonality

A family of aircraft delivers additional cost savings through crew, engine and spare parts commonality. In fact, the four ERJs share nearly 98% common systems and parts.

This high degree of commonality reduces spare parts requirements, permits the use of the same ground support equipment, and allows for standardized training and maintenance procedures. That reduces costs, increases parts logistics efficiency, and improves profitability.

Same crew qualification across the ERJ family means differences training is one of the simplest in the industry. With the benefits of a common family, airline schedulers and crew planners will find last-minute flight changes easy to manage.

Cabin

Designed for both passengers and crew, ERJ cabins are pressurized to 7.8 psi and maintain an 8,000 ft cabin altitude up to a 37,000 ft ceiling.

The three-abreast, 31 inch seat pitch gives everyone a window or aisle seat.

Overhead stowage compartments feature space-saving retractable panels while large wardrobes allow for additional stowage.

Five galley arrangement options let airlines customize their standard of in-flight catering and cabin service.

Lavatory

All ERJs have a 71 cu.ft (2 cu.m) aft transverse lavatory - the largest for this class of aircraft.

The lavatory spans the entire width of the cabin making it ideal for passengers with reduced mobility.

Windows

Large windows are positioned at eye-level and aligned one per seat row.

Their generous size gives passengers a wide angle of vision and helps to create a bright and open cabin environment.

Cargo

A cargo door located at the center of the 9.2 cu.m (325 cu. ft.) compartment helps to expedite loading and unloading.

The large 1.12m x 0.96m door (38in x 44in) and 1.65m (65in) sill height above ground level makes access possible without a belt conveyor.

Engine

The Rolls-Royce AE3007 is designed to simplify maintenance.

Engine inspection & maintenance intervals coincide with aircraft A & C checks. There are borescope ports in each compressor stage and six large access panels for direct access to the engine core.

Blades and vanes can be replaced with the engine on wing and no unique hardware is required to reconfigure the engine for left or right installation. An engine changes requires only 1.25 man-hours.

All major line replaceable units are located on the underside of the engine and positioned for ease of access.

Doors

Embraer knows that every airport is different which is why the main passenger door on ERJs can be one of two types.

A plug-type door is jetway compatible for ERJs operating at large airports with gate parking. The feature ensures seamless transfers between ERJs and mainline aircraft and makes access easier for passengers with limited mobility.

A door with integrated airstairs is ideal for airlines serving airports with limited ground support infrastructure.

Maintenance Checks

ERJ operators perform maintenance checks at these intervals:

ROUTINE CHECK
 100 FH or 14 days

A CHECK
 500 FH

C CHECK
 System - 5,000 FH
 Structural - 5,000 FC
 Corrosion - every 30 months

LARGE JET SUPPLEMENT

Demand is never uniform. Same-day business travelers prefer morning outbound and evening inbound departures. But not everyone wants to fly at the same time.

It's often more cost-effective and competitive to use large-gauge equipment at peak-demand times of the day. Yet for off-peak hours, regional jets often better match capacity to demand.

The combination of ERJs and larger jets enhances competitive positioning, gives passengers a greater choice of flights, maintains frequency and ensures the right number of seats at the right time of day.

TURBOPROP REPLACEMENT

An increase in the speed and range of an aircraft can increase its productivity.

Flying faster and farther with an ERJ allows it to reach destinations sooner and markets to be served more frequently. That, in turn, can generate more seat miles/kilometers. More flights bring more opportunities for revenue.

And by flying above inclement weather, passengers are assured a smooth and comfortable jet ride.

NEW MARKETS

ERJs allow airlines to expand their market catchment areas from a hub, accessing new traffic from cities that were previously served exclusively by competitors or not served at all.

Small units of capacity, like that offered by ERJs, can be a low-risk way of opening new markets. As demand grows, airlines may add ERJ frequency until larger aircraft make economic sense.

LARGE JET REPLACEMENT

An empty seat is lost revenue. Too many empty seats too often means overcapacity.

Finding the right balance between frequency and capacity is important to keep an airline competitive and profitable.

Regional jets can help. Instead of large equipment flown once or twice at peak times, offering ERJs with many frequencies can smooth demand throughout the day.

Passengers not only have more flights from which to choose, airlines can redeploy their larger jets on more profitable routes.
