There is no universally fixed maximum age to start pilot training, but most aviation authorities and flight schools have practical guidelines. Typically, you can begin training at any age if you meet the minimum eligibility (usually 17–18 years old) and can obtain a Class 1 aviation medical certificate, which becomes more challenging to maintain as you get older due to stricter health requirements. While there is generally no hard upper age limit for obtaining a Commercial Pilot Licence (CPL), age affects medical fitness, the ability to complete intensive training, and long-term career prospects, as airlines often prefer pilots who can serve many years before mandatory retirement (usually around 60–65). Older candidates can still successfully complete pilot training and obtain a CPL, but securing employment with commercial airlines may be more difficult because hiring policies prioritize younger cadets who can have longer careers. However, opportunities may still exist in private aviation, charter services, flight instruction, or as second-in-command roles, so older candidates can pursue a pilot career if they plan strategically and maintain medical fitness.
