The following medical tests are conducted for a Class 1 medical certificate:
Family health history: The doctor will ask you questions about illnesses that run in your family. It is important for them to know about this because some diseases like diabetes run in a family.
Hearing test: Your ears will be tested in various ways. You must identify the intensity and direction of sound accurately.
Eye sight test: Many people are worried about this because they wear glasses, well there is nothing to worry, you are allowed to wear them. Your vision must be 6/6 in the test with corrections if necessary i.e. without glasses if you claim to have a perfect eye sight and with glasses if you need them. Severe colour blind people are generally rejected. Blood and urine test. Blood pressure and ECG test. Organ test: Organs like lungs, stomach, etc. are tested to see if they are normal.
Limb test: Limbs are tested to check for deformity and strength. A person with very weak limbs (below normal) will be rejected.
Nervous system test: Basically these are the only tests a pilot has to face. Many people have a misconception about it, when they hear it is tough and they think physical examination involves things like running a marathon or so. These mistakes make me laugh. You are here for an examination, not military selection, don't confuse the word physical examination with physical training. Any average person could clear a Class 1 medical.
Class 1 and 2 medical examinations in India are practically the same:
ECG
X-ray
Ultrasound
Audiometry
Blood Test and Urine Test
Blood Pressure
BMI check
Eye Test
These are the common test in both of Class 1 and 2
In class 1 there was one additional test in which you may be asked to take of your clothes (including underwear) and your genitals will be checked. You may be told to turn my head left and cough while being without clothes. Basically, class 2 medical test is just a practice for class 1 medical test. Don't worry too much, if you passed your class 2 medical you will pass class 2 as well.
Just mind that it does take 2 days for class 1 to get over while class 2 is done in one day. Certificate of being Fit/Temp fit/Unfit is given on the 2nd day itself. If in case any abnormality is found, some recommendations might be issued. After proper care and recovery you may get the medical test done again.
