Class 1 and Class 2 medical certificates are two important categories for pilots. Class 1 Medical is the highest level and is required for those who want to work as commercial pilots or airline transport pilots. It involves stricter health checks including ECG (heart test) eye and vision checks hearing tests lung function blood tests and other examinations to ensure that the pilot can handle the mental and physical demands of flying large passenger or cargo aircraft safely.
On the other hand Class 2 Medical is for student pilots private pilots and recreational flyers. The tests are less strict compared to Class 1 but they still check eyesight hearing blood pressure and general fitness. This certificate ensures that a pilot is healthy enough to operate smaller aircraft safely during training or private flying. As a pilot progresses in career, upgrading from Class 2 to Class 1 becomes mandatory for professional flying.
