An aircraft’s landing gear is otherwise known as the undercarriage. This is the part of the airplane which is a structure made of several parts that supports it while on the ground. With it an aircraft can land, take off, and taxi. The most common type of undercarriage everyone is familiar with is a landing gear wheel. The other types of landing gears include floats and skids.

Landing Gear Wheel Sizes

Landing gear wheels are the most common type of undercarriage and are the ones most people are aware of. Different aircrafts have different dimensions of landing gear wheels. Other than that each aircraft model has a different sized wheel as well. The size and dimensions of the wheel will depend on many factors including the size and capacity of the aircraft.

For instance, if we compare two different models we will immediately see a difference in the dimensions of each model’s nose wheel. A Boeing 747-200 will have its nose wheel dimensions as follows: ply rating 30/32; dimensions 49 x 17 tire. However, a Boeing 767 H32 X will have the nose wheel dimensions as follows: ply rating 20/22; dimensions 14-15. A Douglas DC-9-50 will have tire dimensions at 26.6 x 6.6CH and a 10 ply rating. A Douglas DC10-30 has tire dimensions as 40 x 15.5 and 26/28 ply rating.

Gear Arrangements

Depending on the type of aircraft you’re looking at, there will be different gear arrangements on the each plane. There are basically a couple of conventions regarding gear arrangement. First arrangement has a couple of main wheels at the plane’s front and a smaller wheel at the rear. This type of arrangement is called the conventional undercarriage.

The second type of arrangement is called the tricycle undercarriage. Obviously there will be three wheel assemblies for this type of gear arrangement. Two of these assemblies are located underneath the wings and the third one is under the nose. As you might have guessed, the conventional undercarriage was popular when planes only used propellers and the tricycle undercarriage are more common with today’s modern aircrafts.

Dealing with Larger Aircrafts

Dealing with larger airplanes will of course necessitate the use of larger gears. Not only would you expect that the gears on these colossal aircraft to be a lot larger than what you imagine, there will also be more gears mounted on a larger aircraft as well. The bigger the airplane the more wheels were usually added. For instance the Antonov An-225 has as many as 32 tires mounted onto it.

Another feature of new landing gears is that they are now retractable. This is quite common today since the design is now made more aerodynamic. The size and number of gears on an aircraft will depend on its overall capacity and weight.

Also referred to as a sailplane, a glider is a special kind of aircraft designed primarily for the sport called gliding. It is classified into various types, the most popular of which include the paragliders, hang gliders and motor gliders. Aside from recreation, it also serves other important functions including for research and military applications. Moreover, there are other interesting things to find out about it including the different glider wing dimensions.

The Dimensions of a Glider Wing

The wings of gliders vary in size depending on the competition class. The FAI or Federation Aeronautique Internationale has set these standards. Likewise, this international body is also responsible for governing the world records in astronautics, aeronautics as well as other air sports.

A standard-class glider comes with a 15-meter wingspan, with water ballast and no flaps. Under the 15-meter class, a glider must have a 15-meter wingspan with water ballast and flaps. For the 18-meter class, it must possess a wingspan of no more than 18 meters, with water ballast and flaps. For the open class, the wingspan is not limited as long as the glider does not exceed the maximum weight of 850 kilograms.

Aside from these basic types of gliders, there is also the two-seater class. It is commonly referred to as the Doppelsitzer, which is actually its German name. The maximum wingspan for this particular class is 20 meters. For the ultra-light class, any glider is allowed as long as it does not go beyond the 220-kilogram limit.

Additional Facts and Other Interesting Details

Gliding is a sport that is highly popular in Germany as well as in many other countries. The top German manufacturers of high quality gliders are Alexander Schleicher GmbH & Co., Schempp-Hirth GmbH and DG Flugzeugbau GmbH. Aside from Germany, other manufacturers can also be found in different eastern European countries such as Poland.

A majority of gliders do not need engines although some requires at least one to operate, such as the case of motor gliders. Sailplanes or gliders can be launched using two common methods, which are either by winch or by aerotow. Because of their low long wings, gliders commonly create a high ground effect.

To make things very convenient, gliders are equipped with a number of different technical aids and instruments. The most basic items include the airspeed indicator, compass and altimeter. Additionally, you can also find other items such as an airband radio, a turn and bank indicator as well as a variometer in many gliders. In case of accidents, the time for search and rescue can be reduced significantly with the help of an Emergency Position-Indicating Radio Beacon.

It was once a bit of a fantasy for people in ancient times to hear of huge chunks of metal to fly into the air. The idea was simply impossible for them at the time until now when technology has paved new possibilities. Today we do not only have airplanes, large chunks of steel, flying in the air, they also carry passengers and cargo. Here are the world’s biggest airplanes starting from the very largest one.

An-225 Mriya – World’s Biggest Airplane

You might have thought that the Airbus A380 is the world’s biggest airplane. That plane may be huge but it definitely isn’t the largest one out there. The largest airplane in the world is not a passenger plane but a cargo plane, the An-225 Mriya. Technically, it is a strategic airlift plane that was built by the Antonov Design Bureau. It was awarded by Guinness Book of Records as the world’s biggest airplane in 2004.

The An-225 Mriya was built during the days of the Soviet era. By far, it is still the largest fixed wing airplane built by man. It’s ancestor is the An-124 Ruslan which enjoyed successful commercial usage in Ukraine, Russia, Libya, and the UAE. This plane has a wingspan of 88.4 meters. Its dimensions are as follows: length 73 meters, height 24.1 meters. It was built in 1988 and was outfitted with six engines. Its maximum weight during take off was 600,000 kilograms. Unfortunately, there is only one An-225 in operation today.

Other Large Aircraft

Here are some of the biggest planes in the world. Some may even be considered as the world’s biggest airplane in fields other than cargo.

Airbus A380: This may yet be the world’s biggest airplane among passenger aircraft. The Airbus A380 has a wingspan of 79.8 meters. Its dimensions are as follows: length 72.75 meters, height 24.08 meters. It was built in 2005 and outfitted with four engines. Its maximum weight during take off is 560,000 kilograms.

H-4 Hercules: The Hughes H-4 was dubbed "Spruce Goose" though it wasn’t entirely made of spruce at all. The Hughes H-4 is the biggest flying boat ever built. Sad to say it was only H-4 ever built in history way back in 1947. It has a wingspan of 97.5 meters. Its overall height is at 24.1 meters and length is 66.6 meters. It was outfitted with eight engines and was intended to carry 115,000 kilograms at take off. Its production ended when it was unable to fly properly.

Boeing 747: This is one of the biggest commercial airliners that were ever built. Its original version was built in 1966. However, records show that the ones we see in the air today were designed and built in 1985. It has four engines with a wingspan of 64.44 meters. Its length is at 70.65 meters and height at 19.41 meters. Its maximum takeoff weight is at 181,485 kilograms.

A balikbayan box refers to a box made from cardboard that is used to send packages from overseas Filipino workers to their families and friends in the Philippines. This box is also used by the workers to pack things for their loved ones and they bring this with them when they return to the country. Some of the items that are commonly stored in the box are canned goods, toiletries, electronics, clothes as well as toys. To send it to the Philippines, it should follow the regulations concerning the dimensions of the box. Below are the standard Balikbayan box dimensions.

Dimensions

There are three types of balikbayan box, namely the medium box, the large or the regular box and the extra large box. The width and height of the medium box is 18 inches while the depth is 16 inches. The standard width of the large box has a width and depth of 18 inches while the height is 24 inches. The extra large box has a width of width and height of 24 inches while its depth is 18 inches.

Additional Information and Other Important Details

One of the primary reasons why overseas Filipino workers send balikbayan boxes to their friends and loved ones is because it is economic. If the workers will send the items individually, the shipment will cost them too much. Unlike when they send all the items at once, they can save money for the shipping of the items. The delivery of the boxes may take several weeks or a month.

Another reason for sending the boxes is for the workers to keep in touch with their families. During Christmases many Filipino overseas workers send packages to their loved ones to let them feel that they think of them even if they are not present with their families for the holiday. According to reports, approximately 300,000 balikbayan boxes are sent to the Philippines every year from the United States alone.

Balikbayan boxes are important to the families of the workers because overseas Filipino laborers usually spend months to gather items that they will include in the box. In most instances, the workers wait for shopping malls to give discounts to customers to buy loads of merchandises that they will add to the box. Other Filipinos abroad include used clothes from their friends in the box. The shipping rates for the boxes usually range from $50 to $100. The rates vary on the location where the package will be shipped as well as on the size of the box.

What is the biggest airport in America? What is the biggest airport in the world? There are several interesting facts to know about these airports.

Denver International Airport

What is the biggest airport in America? Popularly called DIA, many deem Denver International Airport as the most spacious airport in America. It is the third biggest in the world after Montreal- Mirabel International Airport. Worthy of mentioning are also Atlanta Hartsfield Jackson and Chicago O’Hare. These latter airfields are known not just for their vast areas but most especially for their busy activities. Atlanta once handled 76.7 million passengers in the year 2002. Chicago handled 66.6 million in the same year.

King Fahd International Airport

Located in Dammam in Saudi Arabia, this airport occupies 780 square kilometers of land and gives people an idea of what is the biggest airport in the world. This international airport is even bigger than some cities in the world. To get an idea, the biggest airport in London, London Heathrow, is only a small fraction of this most spacious airport.

London Heathrow

London Heathrow was once thought to be the best description of what is the biggest airport in the world. It occupies 4.7 square kilometers of area. But then Saudi Arabia came up with the gigantic King Fahd International Airport which dwarfed the one in London. However, another international airfield was built in Asia in 2008 out-sizing the one in Saudi Arabia. Some experts observe that more travelers are going to Asia, and at the same time, there is a growing number of Asian travelers seeing the world. Asian migrant workers are partly the reason.

Gigantic Dragon

In 2008, the biggest airport was sprawled out on a 501-square mile airfield in China. It was finished in time for the Beijing Olympics. It is said to be able to cater to 50 million passengers annually. Thus, to date, China’s giant and hi-tech dragon airport best answers what is the biggest airport in the world. Being the most spacious airport globally, it has 5 levels, 2 of which are underground. It has three main parts: the Domestic Hall, Olympic Hall, and the International Hall. The edifice is a single structure housing everything under one roof.

This huge airport is environment friendly, using natural lighting in several ways to enhance its interior. The designer is very conscious about energy efficiency and has taken this in the building design of this most spacious airport in the world.
