Common sense about flying on an airplane

(1) Prevent airsickness. Airsickness and vomiting are caused by balance organ disorders and poor body adaptation. Generally, as long as you stay calm, eliminate distracting thoughts, and take some anti-motion sickness medicine, you will be fine. If you know you might get airsick, it's a good idea to take your medication 15 minutes before boarding your flight.

(2) Prevent the onset of old diseases: Changes in flight attitude such as take-off, landing, ascent, descent, turns, bumps, etc., as well as rapid changes in light and shade when the aircraft passes through clouds, will stimulate the onset of some diseases. . Patients with encephalopathy caused by blood clots or hemorrhage must not fly; patients with severe concussions should be accompanied by a specialist and take effective preventive measures; patients with mild concussions should carry some painkillers with them; elderly people with vascular sclerosis should You can take a small amount of sedatives before boarding the plane. Patients with colds, runny nose and blocked nose are best not to fly, because the Eustachian tube obstruction may cause the risk of eardrum perforation.

(3) An effective measure to prevent aviation otitis media is to open your mouth and swallow. Opening your mouth or swallowing saliva can of course play a preventive role, but it is not elegant after all. That’s why it’s common to give each passenger a small package of beautifully packaged candies on a flight. Chew a few candies or pieces of gum to keep your Eustachian tubes open. Chewing is the most effective way to prevent aviation otitis media. If the symptoms are not eliminated, you can pinch your nose with your thumb and index finger, close your mouth tightly, and exhale forcefully, allowing the airflow to open up the Eustachian tube and enter the middle ear air cavity to eliminate symptoms such as ear tightness, ear heaviness, ear pain, and ear discomfort. .

(4) Changing seats without permission on an airplane is dangerous. Civil aviation experts also said that in principle, airlines do not allow seat changes, mainly for the sake of aircraft balance. When flying, airlines usually stop checking in for boarding passes half an hour before departure. This half hour is the critical time for flight loaders to balance the aircraft. At this time, the passenger's seat is basically determined, and the loader arranges how to place the cargo in the cargo compartment at the bottom of the aircraft based on the passenger's seat distribution to ensure the balance of the aircraft. Therefore, if passengers change seats without authorization after takeoff, the balance of the aircraft may change, thus posing potential safety hazards to the flight. Frequency of major aircraft accidents

Major accidents rarely occur, and the rate of accidents causing multiple casualties is about one in three million. Air is the safest mode of long-distance transportation, and it's getting safer. Major accidents occur at a rate of one for every 140 million miles flown. Today, it takes 1.4 billion miles before a major accident occurs, and safety has improved tenfold.

Which is safer, flying or taking a car?

According to a comparative study of casualty accidents by the National Safety Council of the United States from 1993 to 1995, flying is 22 times safer than riding in a car. In fact, over the past 60 years in the United States, fewer people have been killed in airplane crashes than in automobile accidents in a typical three-month period.

Which part of flying is the riskiest?

Takeoff and climb to cruising altitude, and descent and landing are the two stages of flight that are most prone to problems. In extremely simplistic terms, takeoff places the highest demands on the aircraft in terms of engine thrust and structural integrity, while approach and landing place the highest demands on the cockpit crew. About three-quarters of serious accidents occur during these two short phases of flight.

Where is the safest seat on the plane?

Some people may ask which position is the safest when flying? From a statistical point of view, airplanes are the safest means of transportation, but they are not 100% safe. Let’s introduce the safest location on an airplane!

Which is the safest place to fly?

According to the "Aircraft Seat KARMA Distribution Map", when an aircraft catches fire, passengers sitting in the front of the aircraft cabin have a 65% chance of escaping; while passengers sitting in the rear have a 53% chance of escaping. Passengers sitting in aisle seats had a 64% chance of survival, while those in other seats had a 58% chance of escape.

According to the above data, the seats with the greatest possibility of escape are the row of seats facing the emergency exit, and the seats in front and behind the emergency exit.

The most dangerous seats are those 6 rows and beyond from the emergency exit. We seem to be like wild geese migrating. We can fly however we want as long as we reach our destination. But in fact, they are queuing up to fly thousands of kilometers or even further, and their routes and flying altitudes are basically unchanged. This is true for birds, and so is the "Iron Bird".

Our planes can't fly as high as they want in the sky, or fly as high as they want.

Planes are also restricted

Planes flying in the sky must follow a certain route, which is equivalent to a road on the ground. Because pilots must master necessary weather, terrain, navigation and other information during flight to ensure the safety of the aircraft. Especially over the airport, the density of aircraft is the highest, including those taking off, landing, and passing through the air. In such a space with such busy air traffic, if planes fly in their own way, congestion and collision accidents will inevitably occur. There have been such accidents recorded in history. Therefore, a specific area is designated above the airport, and aircraft flying in this area must strictly abide by the regulations and fly according to the route designated by the air traffic controller. In addition, in order to ensure the need for airspace for military aviation, certain airspace must be designated as restricted areas or military controlled areas. Therefore, the routes that our aircraft can fly are also very limited and cannot be flown casually.

Flying altitude restrictions

Various aircraft have different performances, and the heights suitable for flying these aircraft are also different. For example, after a large jet takes off, it must quickly rise to an altitude of more than 7,000 meters. Flying at this altitude is both fuel-efficient and fast, but it cannot exceed a maximum of 13,000 meters. Flying further up, its engine capacity is not enough. The operating range of small and medium-sized aircraft is below 7,000 meters. The flying altitude of supersonic passenger aircraft is within 13,000 to 18,000 meters.

Of course these are the reasons why flow control occurs. With so many restrictions, coupled with some special weather reasons, it is inevitable that aircraft will sometimes flow out of control. So when flow control occurs, please be patient, understand each other, and respect each other! Many people will choose to fly to visit relatives and travel. Regarding some people who experience dizziness, chest tightness, nausea, vomiting and other discomforts while taking a flight, Bi Xun, director of the Nutrition Department of the Affiliated Hospital of the Armed Police Medical College, believes that this is related to improper diet before taking the flight. Specifically, the following points should be paid attention to:

Don't overeat and eat less greasy food.

When people are in the air, the blood supply to the gastrointestinal tract is relatively reduced, and the digestive function is weakened. Overeating or eating too much greasy food before taking a flight is not only prone to indigestion, but also increases the burden on the heart and blood circulation, causing dizziness. , nausea, severe cases can cause cardiovascular and cerebrovascular accidents.

Don’t fly on an empty stomach.

Flying at high altitudes increases blood sugar consumption, and fasting can easily lead to hypoglycemia, dizziness, palpitations, sweating and other discomforts.

Eat less "angry" foods.

Eat too many sweet potatoes, leeks, celery, garlic, radishes, and drink soda, beer and other easily "angry" foods before boarding the plane. The lowered air pressure after the plane takes off will expand the gas in the gastrointestinal tract, causing chest tightness. , abdominal distension.

Eat sweets in moderation.

When flying, especially first-time passengers, the amount of sugar consumed in the body will increase due to mental stress and lack of oxygen. Eating candies, chocolate, jam and other sweets appropriately before taking a flight can help maintain blood sugar levels and energy supply in the body, and enhance the ability to withstand hypoxia in the air.

Before choosing to travel by air, diabetics must have a better evaluation and estimate of their health. If blood sugar is not well controlled, it is best to cancel the flight temporarily. At the same time, if you have ketoacidosis, frequent arrhythmia or complications such as hypertension, renal failure, hyperthyroidism, and neuropathy, or if you have a cardiovascular or cerebrovascular accident and are recovering from surgery, you are not suitable for air travel.

Notes for diabetic patients:

First, it is best to test your blood sugar level before taking a flight, and use hypoglycemic drugs regularly as required to keep blood sugar at normal levels. level to avoid accidents. You can also take appropriate anti-sickness and anti-vomiting medications before boarding the plane to avoid airsickness.

Second, be sure to drink plenty of water on the plane. It is best to drink mineral water once an hour to avoid the body's dehydration. You can reduce your food intake appropriately to avoid abnormal fluctuations in blood sugar. If it is a long-distance flight of more than 3 hours, you should eat appropriately to withstand the energy consumption caused by the flight load.

Third, in terms of diet, diabetic patients should prepare their own meals and snacks on the plane. Meals or snacks provided by airlines may not be suitable for diabetics. When a diabetic travels by plane, it is best to prepare suitable food in a carry-on bag to help control blood sugar levels.

Fourth, in terms of seat selection, it is best for diabetics to book aisle seats.

Flying for hours on end increases the risk of deep vein thrombosis (DVT) and blood clots in the legs. People with diabetes should move around more. After getting on the plane, if possible, diabetics can request to change to a relatively spacious economy class exit row seat to better stretch their legs.

Finally, people with diabetes should avoid rushing to board a plane. Rushing and stress before flying can cause blood sugar to rise. Taking a plane requires a series of procedures such as parking, baggage check-in, and security inspection. Domestic flights generally need to arrive at the airport 90 minutes in advance, and international flights generally need at least 3 hours. For this reason, diabetic patients should allow enough time to board the plane calmly.
