In India under DGCA rules a Class 2 Medical Certificate issued to private pilots student pilots and cabin crew is generally valid for 24 months from the date of the medical examination. However if the applicant is aged over 40 years the validity may be restricted to 12 months depending on health conditions. Renewal requires another medical checkup by a DGCA approved doctor ensuring fitness to continue flying duties.
In the United States under FAA regulations a Class 2 Medical Certificate is valid for 12 months for commercial pilot privileges regardless of age. If not used for commercial flying its validity reverts to Class 3 rules 60 months for applicants under 40 years and 24 months for those 40 or older. This system ensures pilots maintain a high standard of health while also balancing medical requirements with pilot activity levels.
