 ANA's annual event: dedicating an ema (votive tablet) to Dazaifu Tenmangu Shrine to pray for success on behalf of students preparing to take the entrance examination. ANA has installed a large ema (votive picture tablet) at Kansai International Airport Terminal 1 as part of a project to support students preparing for entrance exams. Many "wish cards" have already been hung on one side of the ema. Requests are dedicated to Dazaifu Tenmangu Shrine. ANA will make a dedication to Dazaifu Tenmangu Shrine on your behalf. (Scheduled for February) The idea to install these ema was conceived by ANA's Kyushu branch office, which first placed them at Fukuoka Airport in 1993, and they have since spread to airports nationwide. In addition to Haneda, ema (votive picture tablet) are installed at 18 airports (Shin-Chitose, Hakodate, Kushiro, Asahikawa, Memanbetsu, Wakkanai, Sendai, Shonai, Fukushima, Toyama, Chubu, Kobe, Kansai, Fukuoka, Nagasaki, Kagoshima, Naha) and in Kagoshima C...

 When using domestic flights in Japan, check-in and bag check-in can be completed at a machine without going through the manned counter procedures. When you arrive at the airport, please go to this "self-service check-in machine" first. Here you will complete boarding procedures (check-in). The procedure differs depending on whether you are a JAL member or not. For JMB members JAL Card / JMB Card 2D barcode (e-ticket copy) Confirmation number Cell phone with JAL IC function Non-members 2D barcode (e-ticket receipt) Confirmation number Then, complete the procedure by touching the screen with these barcodes. You do not need to use your boarding pass except in special cases. You only need your smart phone or IC card to board the plane. If you have purchased at the reservation stage, completed seat selection, and "Touch & Go" is indicated in the "Boarding Method" field, you can use the JAL Touch & Go service. JAL Touch & Go Service is a service tha...

 ANA Domestic Premium Class Service  Premium Class" is ANA's highest class for domestic flights. ANA's Premium Class seats are available for an additional fee on top of the regular seat fare. ANA Premium Class is available on major ANA aircraft such as the Boeing 777-200 and 787. The number of seats and seat pitch varies by aircraft. On most aircraft, the seat pitch is 127 centimeters. Only some 787 aircraft have a seat pitch of 144 cm. This is because the 787s use international business class seats for premium class on domestic flights. The 787s for domestic flights are 127 cm, the same as the others. The number of seats varies depending on the aircraft: 21 seats for 777-200 and 777-300 aircraft, 8 seats for 737-800 aircraft, and so on. Many aircraft are equipped with USB power and personal lights. In some seats, a console separates the seat from its neighbors, making each seat private. Reclining angles vary by aircraft, but a standard 777-200 seat has a reclining angle o...

 Altimeter is indispensable for safe operation of airplanes During the flight, a TV monitor in the passenger compartment displays the time required to reach the destination, outside temperature, altitude, and other information. Passengers see without question that they are now at an altitude of 10,000 meters, etc. How does an airplane measure its altitude in flight in the first place? There are two main types of altimeters used in airplanes: radio altimeters and high-pressure altimeters. Radio altimeters are used at low altitudes and measure altitude by emitting radio waves toward the ground and receiving back radio waves. This instrument is very accurate, but it can only be used at altitudes of a few hundred meters. Therefore, the main device used is a barometric altimeter. It measures altitude by taking advantage of the atmospheric characteristic that air pressure becomes lower as altitude increases. Incidentally, the same principle is also used in watches for outdoor use. Howeve...

 What are "high wing," "medium wing," and "low wing" indicating wing attachment position? When you board an airplane and sit in a seat near the center of the cabin, you can see the main wings below the window; however, there are actually various ways to attach the main wings, depending on the airplane's performance and purpose. Generally, the wing attachment positions are classified according to their upper and lower positions, such as "high wing," "middle wing," "low wing," and so on. In the case of passenger aircraft, the majority are low-wing aircraft, i.e. The main wings are attached to the lower part of the fuselage, and the wings are visible below the windows. On the other hand, most transport aircraft are high-wing aircraft, meaning that the main wings are attached to the lower part of the fuselage. The typical medium-winged aircraft with its main wings attached in the middle of the fuselage is a fighter plane. Airc...

Meticulous attention is paid to the balance that determines the safe operation of airplanes.  Any plane can't fly stable unless the weight of the plane is balanced front to back and left to right. The reason why passengers are weighed when they check their luggage is to adjust the area where the luggage is loaded so as not to upset that balance. The same goes for the seating position of passengers and the number of passengers; if passengers sit too far forward or too far back, the balance will also be upset. Therefore, no matter how many seats are available, shifting seats without permission is not permitted from a safety standpoint. For example, in the case of a jumbo jet, the center of gravity of the fuselage is located slightly forward of the center of the fuselage, within a range of about 2 meters in front of and behind the center of the area where the main wings touch the fuselage. If the center of gravity deviates even slightly from this position, sensors are triggered and an...

 To fly a large airplane, need a lot of fuel. When boarding an airplane, if you are watching the plane near the boarding gate, you may see the plane refueling from the wing root area. This may seem surprising, but the fuel tanks of passenger planes are located in the wings. In some cases, fuel tanks are located in the fuselage or tail, but as a general rule, they are located in the main wings. At first glance, it may seem that not much fuel can fit in the wings, but a large aircraft can carry several hundred drums of fuel in its wings, or about 1,000 drums of fuel in a jumbo jet! The wing can hold several hundred drums of fuel, or about 1,000 jumbo jets. So why carry fuel in the wings? Airplanes are very heavy aircraft, especially the fuselage, which carries a lot of weight, including passengers and cargo. During flight, the fuselage naturally tries to go down, pulled by gravity. The wings, however, do the opposite, exerting upward force to lift the aircraft. The lighter the wing i...

 To reduce the weight of the aircraft, the tableware used in the fuselage meal has also been made as light as possible. With carbon dioxide emission reductions and rising fuel costs becoming global themes, the most important issue in the field of aircraft development is to make the aircraft itself lighter so that it can fly on less fuel. Research is being conducted daily to reduce the weight of materials used for airframes. Fuel costs can also be reduced, of course, because of the lighter aircraft. Such weight reduction of the aircraft has started with lighter seats and cargo containers, reduced pages in the in-flight magazine, eliminated the in-flight magazine itself, and finally extended to the in-flight tableware. Although weight reduction can be achieved by replacing ceramic dishes with plastic and other materials, the use of plastic rather than ceramic dishes for first- and business-class meals is a difficult problem because it leads to a decline in the level of service.

 Boeing's 737 is a highly valued airliner on the used market The life of an airplane is surprisingly long. but they can fly for more than 20 years without any problem.  It does not mean that you should take good care of it forever. However, this does not mean that you should take good care of your aircraft forever. Fuel consumption and environmental impact will increase if we continue to use too old a model, and the cycle time until a new model is introduced may be long. The longer the cycle between the introduction of new models, the more likely it is that the company's image will deteriorate. However, there are some used aircraft that are highly regarded. Boeing's B737 is one example. In the case of aircraft, models that have been produced in large numbers are popular because best-selling aircraft have a high reputation as such. The Boeing B737 is one of the most popular aircraft on the used aircraft market because of the extraordinary number of Boeing B737s produced. For...

Airplanes cannot back up on their own to depart.  After all passengers have boarded, the plane slowly backs up and leaves the passenger terminal, heading for the runway. At this point, the plane is not actually running backward. A tow truck pulls the plane and backs it backward. Unlike cars and other vehicles, airplanes are not powered by engines to move the wheels or any other special power to travel on the ground. How they run on the runway during takeoff and landing is, simply put, by idling the jet engines that propel them through the air. However, reverse thrust would cause considerable exhaust and noise emissions in the forward direction, and would be extremely dangerous because the cockpit cannot see the rear. In the past, some models were designed for "back-up operation" with reverse thrust, but today the majority of airplanes do not use reverse thrust.

 Why is "Cessna" a big hit and directed in the global market? The "Cessna" is synonymous with small propeller-driven aircraft. Cessna" is the name of the manufacturer of the plane, not the model name of the plane itself. However, the name "Cessna" is so well known that many people think of the small propeller-driven aircraft. In fact, Cessna propeller-driven airplanes have been a big hit all over the world, especially the 17-2s, which has been manufactured since 1956. The "172 Series," which has been manufactured since 1956, has been a huge hit, with a cumulative total of more than 40,000 units. But one of the reasons why Cessna became so popular was because of its excellent safety features. Cessna has always aimed above all else to provide an aircraft that anyone can fly easily and safely. The fact that Cessna is still the training aircraft of choice around the world is a testament to its high level of safety. Another factor is that Cessna ...

 The market for small and medium-sized aircraft is hotter than the market for very large aircraft. are more popular. While most of the talk about new passenger aircraft has focused on large jumbo jets and Airbus A380s, a look at aircraft sales shows that small aircraft are actually selling better. The world's best-selling passenger aircraft is the B737 series, which seats 100-170 passengers, and Airbus' best-selling aircraft is the A320 series, which is the same size as the B737. In short, the global aircraft market is dominated by small aircraft. The world's aircraft market is dominated by small aircraft. Airlines are also focusing on the market for smaller aircraft with seating capacity of less than 100 passengers. Since the world's two largest aircraft manufacturers have not entered this market, several leading manufacturers are competing with each other, and not a few new companies are aiming to enter the market. There are not a few new companies looking to enter th...

 This is how the "flight plan," which is essential for safe navigation, is determined. Airplanes do not fly freely in the sky. They fly according to a flight plan on a well-defined route. Flying in the airspace of another country is particularly delicate, and entering a route other than the approved one may be perceived as an "airspace invasion. However, even with a predetermined route, minor changes are always made depending on the weather and other conditions of the day. Before boarding, the captain holds a briefing with the dispatcher and others at the control center. The captain holds a briefing with the dispatcher and others at the control center before boarding the aircraft and decides on the "flight plan. At that time, the flight altitude and detailed course settings are made according to the "conditions" of the day. In addition, there is no guarantee that the airport where the aircraft is scheduled to land will not be closed in the event of an acci...

 Airframe Maintenance Usually referred to as a preflight inspection (T-maintenance), this includes a visual inspection of the entire aircraft, refueling, and checking the aircraft for departure readiness. There are four levels of aircraft maintenance: A maintenance, B maintenance, C maintenance, and D maintenance. Since A maintenance is performed every 300 to 400 hours of flight time and takes into account the number of takeoffs and landings, it is performed approximately once a month, at night in the hangar, and the aircraft is ready for operation the next day. A maintenance focuses on replenishment of engine oil, hydraulic oil, oxygen, etc., as well as the moving blades, tires, brakes, engine, etc. B maintenance is performed in addition to A maintenance and includes a detailed inspection, especially of the engine. C maintenance is performed every 3,000~4,000 hours of flight time and takes approximately one week. During this period, operations are suspended and a spare aircraft is...

 Leg Loads and Leg Arrangement An aircraft has main gear (main legs) and nose gear (nose legs), and the main legs carry more than 90% of the aircraft's weight. In addition to the weight of the aircraft itself, the load carried by the main landing gear (leg load) is closely related to the strength of the pavement of the runway, taxiway, and apron. The arrangement of the main landing gear also varies, with some having two legs, others having four, and some being attached to the fuselage, others to the wings, and so on. The wheels attached to the main legs can be 2-wheeled, 4-wheeled, or 6-wheeled. and six-wheeled. The combination of leg load, leg arrangement, and number of wheels is designed to distribute the weight of the aircraft so that the pavement is not burdened as much as possible.

 Aircraft Weight The weight of an aircraft is different for each type of aircraft and consists of dead weight, payload (weight of passengers, cargo, etc.), and fuel weight. Which is heavier at takeoff or landing: the aircraft is heavier at takeoff when it is loaded with fuel in addition to passengers and cargo. The maximum takeoff weight is the maximum weight of an aircraft at takeoff as specified for each aircraft type, and the aircraft manufacturer must prove that the stability, maneuverability, and strength requirements of the aircraft are met for this weight. In Boeing's B747 series, a typical large aircraft, the maximum takeoff weight is approximately 395 tons for a B747-400 dedicated to international use and 27 0 tons for domestic use. In the A380 series, the entire fuselage is double-decker, and the weight is approximately 560 tons for the A380-800.

 ”Autopilot" works in most situations, but takeoff is manual Among all vehicles, one of the most automated is the airliner. Airliners, which can be described as "a mass of advanced technology," generally use autopilot in many situations, such as during cruise. Autopilot is the term used to refer to the autopilot system. Autopilot is used to reduce the task of piloting. Piloting duties are left to the computer, making it easier for the pilot to do the head work. While piloting skills are important, flight management skills and coordination with the crew are also very important. You may imagine a machine like a car navigation system, where you set the destination and it will take control of the vehicle on its own. In actuality, autopilots set the flight path data and runway data to be used, but they do not do everything else for you. Landing operations are not automated. This is because the computer cannot decide whether to continue or abort takeoff in the event of unfores...

 Do aircraft drive on the right side of the road or on the left side? Many aircraft need rules to fly safely. Basic air traffic rules are set forth in the Civil Aviation Regulations of the International Civil Aviation Organization. These rules state that when two aircraft are approaching each other facing each other, they are to change course to the right. In other words, airplanes must fly on the right side of the road. However, there is no time to visually change course if a jet flying at high cruising speed approaches facing it, since the facing speed will be more than 1000 km/h. To prevent this from happening, aircraft flying by instrument flight system have their flight altitude determined by their course. An aircraft heading east on an east-west air route will fly at odd X 1000 feet, while an aircraft heading west will fly at even X 100 0 feet. Which of the approaching aircraft will yield the right of way? In principle, pedestrians have priority at crosswalks, but even in the...
