Second, the psychological quality conditions
The Air Force also has strict regulations on the psychological quality of candidates, and the relevant departments will organize experts to conduct a strict inspection of the psychological quality. Candidates should have a strong interest and desire for flying; Open-minded and cheerful; Courageous and decisive, strong willpower; Emotional stability and strong control; Advanced intelligence such as understanding and memory; Quick thinking, flexible response, coordinated limbs, accurate orientation judgment and strong imitation ability.
Third, political conditions.
My qualifications: Students must support the Party's line, principles and policies, adhere to the Four Cardinal Principles, love China, love the people, love the socialist motherland, love the people's army, be advanced in thinking, have an innocent history, have a decent style, be loyal and honest, have good moral quality, abide by the law, perform well in reality, and be determined to devote themselves to the cause of flying voluntarily to defend the motherland and the people's peaceful labor.
Students in any of the following circumstances are not eligible for registration:
1, backward in political thought and dissatisfied with the party's current policies;
2. Having received criminal punishment or punishment by the public security department;
3. Rogue, theft, gambling, fighting and other illegal acts;
4. Participate in illegal organizations and activities;

(2) Family conditions: Family members and close relatives support the party's line, principles and policies, with a clear history and no major problems.
(3) Registration attitude: students are voluntary and parents support them.
Fourth, cultural conditions.
According to the person in charge of a city's recruitment office, the cultural requirement in the registration is "the person who has passed the unified entrance examination (English or Russian as a foreign language) for ordinary colleges and universities nationwide and is expected to achieve the minimum admission control stipulated by the Air Force."
The items and sequence of the preliminary physical examination for recruiting pilots are as follows:
1, asking about medical history;
2, ophthalmology: vision, color vision, phoria, fundus;
3. Surgery: height, weight, sitting height, leg length and arm length;
4. Internal medicine: blood pressure, pulse, heart, liver, spleen and kidney;
5. Otolaryngology: ear, nose, mouth and hearing.
▲ ophthalmology
According to statistics, the number of flight students who are eliminated due to poor eyesight accounts for four-fifths of the number of people eliminated from ophthalmology every year, which requires schools and students to attach great importance to vision problems.
Attention should be paid to the eyesight examination: excessive mental stress will lead to poor eyesight, so you can do some slight activities to relax your body before the examination. Excessive fatigue and lack of sleep will lead to poor eyesight, and these factors should be avoided as much as possible. Physical examination conditions not only stipulate vision, but also strictly stipulate diopter. If the diopter exceeds the standard, it will be unqualified.
Ophthalmic phoria examination is used to check the imbalance of extraocular muscles. Our country has strict regulations on the number of hidden slopes. If the highest altitude is found in the three inspections, the re-inspection will not be carried out unless the control essentials are not mastered. Candidates must look at the light source in front of them during the exam; After the adjustment point coincides with the straight line, do not reverse the adjustment point ... >>
Question 2: I want to test pilot. What are the requirements? This year, students recruited from high school students to develop flying skills. The training of "cultivating students" is carried out by combining academic education with flight skill training. During the four years in school, students should not only complete the credits stipulated in academic education, but also obtain eight kinds of qualification certificates for entering transport airlines. When recruiting "talented students", some schools accept both arts and sciences, such as the Civil Aviation Flight Academy of China, and some schools only recruit science students, such as Nantah.
Recruiting "nurturing students" generally starts from June 65438+ last year 10. Because schools and students come from different provinces and cities, the specific recruitment time is different, but the recruitment process is basically divided into six links: publicity, registration-physical examination (including psychological quality test)-political examination (those who pass the physical examination)-cultural examination (taking the college entrance examination, foreign languages are limited to English)-admission-physical examination after admission.
Candidates should pay special attention to the prevention of common diseases, such as respiratory tract infection and gastrointestinal tract infection. At the same time, the reporter suggested that all students who are determined to devote themselves to the cause of blue sky should take part in more sports on weekdays, because sports can exercise and enhance the coordination of limbs, which is very important for a professional pilot. As far as the general physical requirements for applying for civil aviation flight technology specialty are concerned: the height is between1.65-1.85 meters; Weighing more than 5 kg; The naked eye vision of both eyes on the circular eye chart is above 0.7; No color blindness, weak color. At the same time, those who have the following medical history or signs should not participate in the registration: first, those who have craniotomy or thoracotomy; Second, frequent low back pain, limb deformity or obvious physical deformity; Having chronic gastrointestinal diseases or infectious hepatitis after the age of three or seven; Four, family and I have mental illness, epilepsy (epilepsy) or I have sleepwalking, often headache and stuttering; Five, suffering from meningitis, tuberculosis or motion sickness, seasickness, obvious strabismus, etc.
If candidates can successfully pass the physical education, politics and culture exams, then the psychological quality test is a crucial link. At present, only the flight academy uses the self-improvement psychological test system imported from Hanseatic, Germany, which tests the potential of candidates through three parts: paper-and-pencil test, man-machine dialogue and psychological heart-to-heart. After synthesizing the information from all parties, the reporter found that the psychological test mainly tests the psychological quality and coordination ability of candidates to determine whether candidates are suitable for flying careers. Therefore, when taking part in the psychological test, candidates can achieve ideal results as long as they eliminate the psychological burden such as nervousness.
Memorandum of application conditions
It is understood that the manpower, financial resources and material resources needed to train a qualified pilot are almost equivalent to the gold value of a normal human body weight. Therefore, in order to become a civil aviation pilot, candidates need to go through many strict "customs". For example, the physical examination should be in accordance with the "Standards for Physical Examination and Appraisal of Civil Aviation Recruiting Flight Students" (the contents involved can be consulted online), including a relatively complete psychological test; Politically, candidates need to pass the examination of the Provisions on Political Conditions for Civil Aviation to Recruit Flight Attendants and Flight Attendants issued by the Civil Aviation Administration, the Ministry of Education and the Ministry of Public Security.
As far as the general requirements for applying for civil aviation pilots are concerned, the height is between1.65-1.85 meters; Weighing more than 55 kilograms; The naked eye visual acuity of binocular ring chart is above 0.7, and there is no color blindness and weak color. At the same time, those who have the following medical history or signs should not participate in the registration: first, those who have craniotomy or thoracotomy; Two, the limbs are incomplete or the body is obviously deformed; Having chronic gastrointestinal diseases or infectious hepatitis after the age of three or seven; Four, my family and I have mental illness, epilepsy, or I have sleepwalking, often headache and stuttering; Five, suffering from meningitis, tuberculosis or motion sickness, seasickness, obvious strabismus, etc.
If candidates can successfully pass the physical, political and cultural examinations, then the psychological quality test is a crucial link. At present, the Flight Academy uses a self-improvement psychological test system imported from Lufthansa, Germany, which tests the potential of candidates through three parts: paper-and-pencil test, man-machine dialogue and psychological heart-to-heart. After synthesizing the information from all parties, the reporter found that the psychological test mainly tests the psychological quality and coordination ability of candidates to determine whether candidates are suitable for flying careers. Therefore, when taking part in the psychological test, candidates can achieve ideal results as long as they eliminate the psychological burden such as nervousness.
In addition, during the physical examination, candidates should pay special attention to the prevention of common diseases, such as respiratory tract infection and gastrointestinal tract infection. At the same time, the reporter suggested that all students who are determined to devote themselves to the cause of blue sky should take part in basketball and other sports on weekdays, because sports can exercise and enhance the coordination of limbs, which is very important for a professional pilot ... >>
Question 3: What do ordinary civil aviation pilots need? My friend, although I am not a pilot, I almost flew into the blue sky at first. I solemnly advise you not to expect any "customs clearance skills"! Flying is no joke. Physical examination must be realistic. No, no! Even if you muddle through some measures, you will eventually get what you deserve. The risk of flying is very high. Do you think it's worth it if something happens in the sky because of your physical condition and you lose your life?
To apply for the flight academy, you must first have two physical examinations two or three months before the college entrance examination. The first is the initial test, which is generally divided into four major departments: ophthalmology, otolaryngology, surgery and internal medicine. Candidates are generally required to check ophthalmology first, because ophthalmology has the highest elimination rate. Most candidates will be eliminated in this subject, and there is no need to look up subjects in the future. When I applied for the exam that year, there were 10 boys enrolled in the whole school, and as a result, seven of them were brushed off in the first pass of ophthalmology. Ophthalmology mainly examines vision and fundus, requiring normal vision, no diseases such as myopia, hyperopia and trachoma, and no defects such as color blindness and color weakness. Pilots use a special "C" meter to check their eyesight, which has eight directions. It is far more difficult than the "e" list.
The second level of otolaryngology should check the health status of hearing, smell, teeth and mouth, and the elimination rate is not low. Even if only 1 tooth is filled, it is difficult to pass.
Surgery and internal medicine are similar to general hospital physical examination, and the pass rate of initial examination is generally higher.
Generally, the proportion of those who pass the initial examination is about 10%, and those who are selected will be re-examined in a closed way. Candidates live in concentrated communities and can't go home. It usually lasts 2 to 3 days. The content includes very detailed physical examination, exercise and physical fitness test, coordination and balance test, will quality test and so on. I won't elaborate on the specific subjects. In short, most people who pass the initial inspection will be eliminated at this level. The rest are "excellent products" that choose the best among the best.
If you pass the second interview, you will be qualified. Then, after passing the political examination, candidates can fill in the Air Force Flying Academy during the college entrance examination. As long as the test scores exceed the minimum admission line for undergraduate students, they can be admitted. Political examination and grades are relatively easy to pass.
Flight cadets should be checked for the third time immediately after entering the school, and the content is more detailed than the second time. Those who fail will be transferred to the ground service major, and there will be no more opportunities to fly into the blue sky. In the later learning process, some students with relatively low grades will be brushed off every semester. In the end, the rest accounts for about 30%-40% of the enrollment. These people will become real pilots.
If you start from the initial registration, less than 2% of people actually become pilots. These people are also in good physical condition, but in the end most of them can't fulfill their dream of flying, which shows the strict standards. Those who barely pass the initial examination with minor defects will almost certainly be eliminated after entering school. So I advise you to give up again, although this suggestion is a bit cruel. In my personal experience, it is better to give up at the beginning than to be eliminated at the last minute after hard work! Long pain is better than short pain!
Attached is the civil aviation industry standard of People's Republic of China (PRC).

Question 5: There are so many requirements for being a civil aviation pilot that you can't finish it without copying it. Actually, I don't think you need to know everything. Many physical examination items, such as height, it is useless for you to know the standard in advance. What's the use of knowing the standard in advance if it is not up to standard? What's more, different companies have different physical examination requirements. CAAC documents are only the minimum standards, and most airlines will require higher standards. As far as vision is concerned, some require a C-word table of 0.5 or above, while others require a C-word table of 0.3 or above. There is no absolute answer. There are still some vague physical examination standards. For example, for many surgical history and trauma history, it depends on the physical examination doctor's own mastery of standards and the comprehensive quality of students.
So I think you just need to know a rough idea. For those things that can be changed in time, such as weight, try to be close to the standard, and the rest is in your destiny. Mainly in the following aspects:
1, height, boys generally require 1.7 meters or more, girls 1.65 meters. Moderate figure, body mass index 18.5 ~ 23.9 (please calculate the body mass index yourself), and the leg length is at least 74 cm.
2, eyesight at least, at least you should be able to see the C font above 0.3, that is, the E font is about 4.5-4.7. The diopter cannot exceed 300 degrees. Astigmatism should not exceed 200 degrees Can't do myopia correction surgery, can't use orthokeratology.
3. Those who have a history of brain, chest and eye surgery are unqualified. Cholecystectomy failed. Kidney calculi of gallbladder is unqualified. Individual identification of gallbladder polyps, hepatic hemangioma and hepatic and renal cysts may be qualified or unqualified.
4. If you have bromhidrosis, do surgery quickly.
5, blood pressure, heart young people generally have no major problems. But many of them are still unqualified because of high blood pressure.
6, severe scoliosis, pelvic tilt, unqualified.
7. If you have other surgical history and hospitalization history, it is best to provide medical records and surgical records during physical examination.
8. Ten days before the physical examination, eat lightly, do not drink, take medicine, listen to things without wearing a mobile phone, and do not play in noisy environments, such as ktv. Exercise moderately and don't get hurt.
Otherwise, you don't need to know.
The score requirement depends on where you are. For example, Yunnan and other areas with low scores in the western college entrance examination must go to the second line. In areas with high grades in the central and eastern regions, there are also opportunities under the second line at 30: 40. English must be above 90%. Individual recruitment units should also examine their English listening and speaking ability during the interview. It is best to study science.
Question 6: Civil aviation pilots who meet one of the following conditions cannot apply:
1, the height of boys is less than 170 cm or more than187cm;
2. Weighing less than 50 kg; Weight calculation method: weight KG= (height CM- 1 10)+ (height cm-110) *10%.
3. Diseases or deformities of bones and joints;
4. Obvious "O" or "X" legs;
5. Long-lasting skin diseases, such as tinea capitis, eczema, psoriasis, chronic urticaria, etc.
6. Chronic gastrointestinal diseases;
7, hepatitis or hepatosplenomegaly, HbsAg positive;
8, nephritis or hematuria, proteinuria;
9. Family history of psychosis and history of epilepsy;
10, the facial features are obviously asymmetrical;
1 1, motion sickness, seasickness;
12, stuttering;
13, pus in the ear, poor hearing, frequent tinnitus;
14, naked vision less than 0.3 (table C) or corrected vision less than1.0 (table C) or diopter greater than 300 degrees; Those who have undergone myopia refractive correction surgery; Color blindness and color weakness;
15, pulmonary tuberculosis;
16, severe trachoma or trichiasis;
17, immediate family members have criminal records or join cult organizations;
18, over age. (Senior three graduates are required to be born after1August 3, 9941,sophomores and juniors1August 3 1, and seniors1August 3, 9901).
This is the standard of self-recommendation. For more details, please write privately.
Question 7: What are the disadvantages of being a civil aviation pilot?
1. is too restrictive. With the rapid development of domestic aviation in recent years, airlines buy more and more planes and need more and more pilots. In order to make a profit, the company will let everyone fly more and more, resulting in basically no extra time to do what they want to do. I feel that every day besides flying, I just go home to rest. The point is that I flew again before I had a rest.
2. less concern for the family. Because there are many days to fly, most of them are in the sky, or abroad, and there is too little time at home every month. Taking care of the elderly, children and families is basically empty talk. If you don't understand, your family will complain
3. The life circle is too narrow. The scope of work determines that I spend most of my time in contact with colleagues in the company and airport staff. I have limited knowledge of other industries, few friends, and limited space and scope for entertainment.
4. Work pressure is relatively high. The domestic aviation safety cycle hours are already very high, far higher than those abroad. Therefore, leaders hold meetings every day to talk about safety, and everyone's nerves are very tight. Once the safety bottom line is triggered, it will be miserable. It's harder to turn over than to ascend to heaven.
5. It is harmful to health. Although I have a physical examination once a year, I want to exercise when I am too tired to fly, but I don't have much energy. Some organs of the body will be overloaded for a long time, and will fall behind over time, and the body will collapse when it is old.
Once you can't fly for irresistible reasons, you will find that you know nothing but flying. Although the possibility of this happening is not very high, it is inevitable.
That's all I thought of. I want to know more about the chat list. I hope it helps you.
Question 8: What are the requirements for airline pilots to participate in the selection of senior three special skills, mainly physical examination? Those who pass the college entrance examination will be reported to Tefei College, and they will be admitted according to their grades. They will become pilots after graduation.
Question 9: When pilots have any physical requirements, China Civil Aviation recruits flight cadets to implement the new physical examination standard, and the requirement for naked eye vision is lowered from 1.0 to 0.7, while the standard for height and weight has not changed much. The new standard requires that the visual acuity of any eye should be above 0.7 and that of both eyes should be above 1.0. If the naked eye vision of any eye is less than 0.7, the following conditions must be met at the same time: the naked eye far vision is not less than 0.3; Corrected vision is not less than1.0; The diopter shall not exceed plus or minus 3.00D (spherical lens equivalent). The new standard also clearly stipulates that anyone who has undergone corneal refractive surgery is regarded as unqualified vision. According to the Admissions Office of the Civil Aviation Flight Academy of China, pilots fly planes at an altitude of several thousand meters, relying entirely on radar navigation. The reduction of pilots' vision standards will not affect flight safety, and excellent students can be selected in a wider range. The 2007 annual report of China Civil Aviation Flight Academy will be held this month, and the physical examination will be carried out in full accordance with the new standards. 1 The height of boys is less than 170 cm or more than187cm; 2. Weighing less than 50 kilograms; 3. Diseases or deformities of bones and joints; 4 obvious "O" or "X" legs; 5 long-term incurable skin diseases, such as tinea capitis, eczema, psoriasis, chronic urticaria, etc. 6 chronic gastrointestinal diseases; 7. Hepatitis or hepatosplenomegaly, HbsAg positive; 8. Nephritis or hematuria or proteinuria; Family history of psychosis and epilepsy; 10 The five senses are obviously asymmetrical; 1 1 carsick and seasick; 12 stuttering; 13: excessive ear flow, poor hearing and frequent tinnitus; 14 visual acuity is less than 0.7(C word table); 15 tuberculosis; 16 severe trachoma or trichiasis; 17 physical examination standards for air force pilots whose immediate family members (within three generations) have been detained, responsible, killed or joined a cult organization 1.
