In terms of range capability, the 777-300 can serve routes up to 6450 statute miles (10,370 km). The 777-300 has nearly the same passenger capadty and range capabUity as the 747-100/-200 models but bums one-third less ftiel and has 40% lower maintenance costs. Of course, this results in a lower operating cost. 

Baseline maximum takeoff mass for the 777-300 is 580,000 lb (263,080 kg) the highest maximiun takeoff weight being offered is 660,000 pounds (299,370 tg). Maximum fuel capadty is 45,220 gal (171,160 L). The 777-300 has a total available caigo volume of 7080 ft (200.5 m ).

The Generation III reactors Evolutionary Pressurized Reactor has expanded safety features such as 2 separate 51 inch thick concrete walls with the inner one lined with metal. Each of the walls is strong enough to withstand the force of a large commercial airplane.

The pressure of the air on the outside of your eardrums is decreasing faster than is the pressure of the air on the inside of your eardrums. FYI, commercial airplanes maintain a cabin pressure that is equal to the pressure one experiences at about 2400 meters (8000 feet) up a mountainside.

Find out about the wall construction of the cabins of large commercial airplanes, the range of ambient conditions under which they operate, typical heat transfer coefficients on the inner and outer surfaces of the wall, and the heat generation rates inside. Determine the size of the heating and air-conditioning system that will be able to maintain the cabin at 20°C at all times for an airplane capable of carrying 400 people. 

Commercial airplanes begin to pressurize their cabins at altitudes below 10,000 feet. Above this altitude cabins have to be pressurized, if the passengers do not use additional oxygen supply. Without oxygen, a pressure of about 10 p.s.i., corresponding... 

An example of air pollution in a confined space is the air in an airplane. The air in commercial airplanes contains reduced levels of oxygen, increased levels of carbon monoxide, carbon dioxide, ozone, volatile organic compounds and particulate matter. These contaminants have led to cockpit crew, cabin crew, and passenger complaints of headache, fatigue, fever, and respiratory difficulties. Another example of confined space air pollution is the release of solvent fumes when interior walls of buildings with inadequate air circulation are painted. ... 

During the decade from 1920 to 1930, the automobile manufacturers produced complex transportation mechanisms from metal, rubber, glass and engines, with electric, hydraulic and mechanical controls. The commercial airplane industry of the era produced complex transportation mechanisms made of metal, rubber, glass and engines, and had electric, hydraulic and mechanical controls. It would seem natural these two similar complex transportation mechanisms should be made by the same manufacturers. Of the automobile manufacturers in the United States, only Ford ever tried to manufacture aircraft. The Ford Trimotor was an excellent aircraft but was only manufactured for a few years.

The pitot-static tube is the standard device for measuring the airspeed of airplanes and is often used for measuring the local velocity in pipes or ducts, particularly in air pollution sampling procedures. One can easily identify the pitot-static probes projecting from the front of modern commercial airplanes look next time you are at an airport. For measuring flow in enclosed ducts or channels the venturi meter and orifice meters discussed below are more convenient and more frequently used.

Every hour, up to 6.2 t of waste are incinerated. The combustion of one ton of waste yields, on average, 16 000 MJ. The carbon dioxide emission amounts to only half of the hourly emission rate of a commercial airplane. 

The history of the modern adhesives and sealants industry is closely tied to the development of the aircraft and aerospace industries. From the earliest flights to the most modem aerospace equipment, light weight has been one of the most vital considerations. Adhesive bonding was an ideal joining method for the early wood and textile aircraft, and today is the most important joining method for aluminium, titanium, and other metals in advanced military air- and spacecraft and some advanced commercial airplanes.
