What is the purpose of a "Special" flight inspection?

The purpose of a "Special" flight inspection is primarily to evaluate new navigational aids. This type of inspection is crucial because it assesses the performance and reliability of newly integrated systems to ensure they meet necessary safety and operational standards before being put into regular service. It involves a comprehensive analysis of the new equipment under various conditions to confirm its accuracy and effectiveness in aiding navigation, which is vital for aviation safety.

The focus on new navigational aids ensures that any potential issues are identified and rectified early in the system's lifecycle, helping to maintain high operational standards in aviation navigation.
