Private registered, non-commercial aeroplanes that had previously been for military operations would operate under which flight authority?

• A. Standard C of A
• B. Special C of A - Limited
• C. Restricted C of A
• D. Experimental C of A

Answer: (B)

Private registered, non-commercial aeroplanes that were previously used for military operations typically fall under the category of Special Certificate of Airworthiness - Limited. This designation allows such aircraft to operate under certain limitations that are appropriate given their history and potential modifications from military use.

The Special C of A - Limited is specifically designed for aircraft that do not meet all the requirements for a standard certificate due to their unique history, such as modifications or additional operational restrictions stemming from their military background. This category allows for safer integration of these aircraft into civilian airspace while accommodating their operational limitations.

In contrast, a Standard Certificate of Airworthiness would require full compliance with the regulations applicable to civilian aircraft, which may not be feasible for military surplus aircraft that need specific modifications or operating conditions. A Restricted Certificate of Airworthiness is typically used for aircraft that are limited to specific operations, which does not apply here since the Special C of A - Limited covers the specific needs of former military aircraft. The Experimental Certificate of Airworthiness involves aircraft used for research, development, or training that may not meet all requirements for standard operation, which is also not suited for an aircraft simply transitioning from military to civilian use.

Thus, the designation of Special C of A - Limited accurately reflects the operational capabilities
