How long is a class rating valid for?

A class rating is typically valid for 2 years from the date of issue. This is established to ensure that pilots maintain their proficiency and currency in operating aircraft of that class. After 2 years, pilots are required to demonstrate their continued competency, which can involve meeting specific requirements such as flight hours or completing additional training. This regular evaluation helps to ensure safety in aviation by ensuring that pilots have up-to-date skills and knowledge relevant to the aircraft they are permitted to fly.

The duration of validity is designed to balance the need for experienced operation with the practicalities of flight training and pilot operations, making 2 years the appropriate time frame to ensure pilots remain proficient.
