1999 - 2010 Boeing 757-300

Being 757-300 is a stretched version of the Boeing 757-200 this airplane measures 23 feet 4 inches (7.1 meters) longer. The extra length permits it to carry 20 percent more passengers than the 757-200 and also increases the available cargo volume by nearly 50 percent.

So, the Boeing 757-300 can accommodate up to 289 passengers in charter service, having about 10 percent lower seat-mile operating costs than the 757-200, which means that this airplane has the lowest seat-mile operating cost in its market segment.

It is not a replacement of the Boeing 757-200, as many others have thought and both models are in production.

Range 3485 n miles

The 757-300 maintains the steadfastness and simplicity of the 757-200.

Both versions have the same flight deck and operating systems, but some characteristics have been adapted.
Besides an extended fuselage, the modifications on the 757-300 consist of: new tires, brakes and wheels; a tail skid; landing gear and strengthened wings.

Also the Boeing 757-300 has the same type of rating as Boeing 767. 
This permits any pilot trained to fly one model to be capable to fly the other model with minimal extra familiarization, saving training time and costs.

Commonality offers airlines other advantages such as enhanced operating efficiency from reducing spares inventories, reducing training requirements and greater adaptability in assigning flight crews.

Boeing 757-300 Exterior

The aircraft’s wing, landing gear and portions of its fuselage have been reinforced and new wheels, tires and brakes added to handle the extra weight.

Wing Span 124 ft 10 in (38.05 m)

Because the airplane is longer, Boeing made several adaptations to protect against possible damage from tail strikes during takeoffs and landings.

It was added a retractable tail skid like that on the Boeing 777-300, this has a body-contact indicator which informs the pilot if pilot if the body of the aircraft has made contact with the ground, despite the tail skid.
That data helps prevent unnecessary and costly air turn-backs.
Because the wings are less swept and thicker through the center than those on earlier Boeing airplanes, this will allow a longer span.
The lower wing surface is slightly flatter, and the leading edge is somewhat sharper. This improves lift, reduces drag and makes for improved aerodynamic efficiency and low fuel consumption.
The only difference between the 757-300 and the 757-200 wing is that the former has been structurally reinforced to handle the increased load.

Boeing 757-300 Interior

The new look of Boeing 757-300 was inspired from Boeing 777 interior design.
You will observe at the new interior a large, user-friendly cabin with a comfortable, enjoyable environment.
Two of the most important characteristics of this airplane are: the durability and the flexibility. Therefore the interior floor, wall and seat materials can be cleaned without difficulty.

The interior features new soft, indirect lighting that improves cabin ambience along with a smooth sculptured ceiling, giving the cabin a more open, spacious feel. The curved ceiling panels offer up to three additional inches of headroom. The passengers will have more storage space because of the longer overhead stowage bins.

Cargo 2,370 cu ft (67.1 cu m)

The extra space was created by superior engineering on the bins that eliminated the need for an internal support brace. The environmental control system for the passenger cabin has been modified to accommodate the additional passengers.

It have been added a larger precooler, an additional temperature and more powerful fans.
This model has 8 standard doors, with 4 over-the-wing exit doors, 2 on either side. The 757-300 also is outfitted with vacuum lavatories that mean the service time will be reduced.

Other than the interior, most of the changes to the 757-300 were made to have capacity for the extended fuselage and increased passenger and cargo load.
The maximum takeoff weight was increased to 272,500 pounds (123,600 kg) to preserve the passenger/cargo load capability.

Boeing 757-300 Avionics

The flight deck of the 757-300 is designed for two-crew member operation and equipped with digital electronic displays.
A computerized, fully integrated flight management system (FMS) provides for automatic guidance and control of the airplane from immediately after takeoff to final approach and landing.
Linking together digital processors controlling navigation, engine thrust and guidance the FMS will give the guarantee that the aircraft flies the most efficient route and flight profile for reduced flight time, fuel consumption and crew workload.
The pilot and also the copilot have a pair of electronic displays for primary flight instrumentation and navigation. One display indicates an electronic attitude director indicator and the other an electronic horizontal position indicator.

Global positioning system

Several flight deck improvements have been made on both the 757-300 and the 757-200. Now on Boeing 757-300 have become standard: the Pegasus flight management computer (FMC), the enhanced engine indication and the crew alerting system (EICAS). Having the FANS functions the operators can use sophisticated systems, such as global positioning system (GPS) sensors and satellite communications (SATCOM) and they will benefit of new communication, navigation and air traffic management systems for more professional routing and decreased trans-oceanic traffic separation.

The EICAS upgrade replaces existing computers with enhanced devices that are software loadable.

The new EICAS has improved built-in test equipment (BITE) functions that permits for enhanced self-diagnosis of faults in a more readable format. On-board software loading allows operators to work with the same EICAS computer as a replacement on any 757 or 767.

That diminishes the necessary inventory of spare parts.

Other developments to Boeing 757-300 are:

• a new software-loadable flight control computer (FCC);
• an improved ground proximity warning system (EGPWS), intended to reduce controlled flight into terrain;
• an enhanced wind shear warning system;

The 757-300 also has the latest technology air data/inertial reference system (ADIRS).

Boeing 757-300 Engines

The 757-300 and 757-200 share many of the same characteristics. Both have high-bypass-ratio engines and a wing design that help make them two of the quietest, most fuel-efficient jetliners in the world.

The engines are from Rolls-Royce or Pratt & Whitney, having a thrust rating of 43,500 (193.5kN) and 42,600 pounds (189.4kN) respectively.
The fuel capacity was not improved and therefore the range was reduced to 3,395 nmi (6,287 km).

Rolls-Royce RB211-535E4B thrust =43,500 lb (193.5 kN)

It has proved popular with charter airlines for its competence and dense capacity. For Boeing to have increased the fuel capacity, it had to fortify the undercarriage and other areas to enhance the MTOW.
The 757-300 series was available for acquire with four engine alternatives: either 43,100 lbf (191.7 kN) Rolls Royce RB-211-535E4-B turbofans, 43,850 lbf (195.1 kN) Pratt & Whitney PW-2043 turbofans and older models known from 757-200 series, PW2037 and PW2040.
Only Northwest Airlines ordered the 757-300 with the Pratt & Whitney engines.

Until July 2009 Boeing sold 51 aircraft for: Continental Airlines (17), Delta Air Lines (16), Condor Airlines (13), Arkia Israel Airlines (2), Thomas Cook Airlines (2) and Icelandair (1).
