Which of the following is not an objective of the PD 1570?

The primary objective of PD 1570, also known as the Presidential Decree on the Regulation and Practice of Aeronautical Engineering, is to establish a framework for overseeing and ensuring the integrity of the profession. Options A, C, and D align with the goals of this decree, which include the standardization and regulation of the field, oversight of the practice to ensure compliance with professional standards, and facilitating the registration of qualified individuals within the profession through examination.

Certifying aeronautical engineers specifically for type rating trainings does not fall under the direct objectives of PD 1570. Type rating pertains more to the operational qualifications necessary for pilots and specific aircraft. The regulation and practice of aeronautical engineering focus more on the engineering aspects rather than operational certifications, which explains why this option is not consistent with the main aims of the decree.
