You will notice that the forms use a lot of medical terminology, much of which is Latin. Rather than asking forum users for definitions, please use Google or Wikipedia if you want to know what a term means.
An Ophthalmologist will do a detailed eye examination. These are the vision standards and here is the form the Doctor will complete. If you have concerns about whether or not you can pass the eye examination, print the standards and have your eye doctor tell you if you meet them or not. If your vision is within the acceptable range, but you wear glasses or contact lenses, bring them with you to the exam. The CAA use the Ishihara Plate Test to check for colour vision. While I have linked to sample plates on the Internet, they are not adequate for a final determination of your colour vision because computer monitors transmit light, while the actual plates reflect light. The above link is provided simply to show you what the test will be like. If you fail it, they may use a lantern test to double check the result.
An Otorhinolaryngologist (Ear, Nose, Throat Dr.) will conduct a detailed exam and an Audiologist will test your hearing. Here is the hearing standard and the form the doctor will complete.
Very few young people fail the Initial Class 1 Medical Examination. Unless you have a known medical issue that might cause you to fail, I recommend attending Skills Assessment before undergoing the medical exam.
The sort of conditions that will cause failure can be categorized:
Conditions that impair sensory input:
- Poor hearing
Poor vision
- Severe Asthma (smoke and fumes, stress or rapid decompression can trigger an attack)
Heart problems
Epilepsy or other seizure disorders
Diabetes
Psychological disorders
