All pilots who work in commercial aircraft must have a first-class medical certificate. This certificate adheres to the strictest medical guidelines. A medical certificate holder must be mentally and physically capable of safely exercising the privileges of the appropriate license.
Eyesight, ear, psychical examination, electrocardiogram (ECG), lung function, cholesterol blood, hemoglobin blood, chest X-ray, urine, and time of validity are all required for a first-class medical certificate. ECG can reveal problems with cardiac rhythm or impulse conduction, and it can also reveal a shortage of blood flow to the heart muscle. For PART-FCL Class 1, a chest X-ray investigation is not necessary, although it may be required if clinical or epidemiological reasons warrant it. The Lung Function Test measures your capacity to take deep breaths and evacuate air from your lungs. A physical examination is a general check to ensure that everything is in working order. The lungs, heart, blood pressure, stomach, limbs, and neurological system will all be covered.
