What is one of the privileges of having a Certified Flight Instructor - Instrument (CFI-I)?

A significant privilege of holding a Certified Flight Instructor - Instrument (CFI-I) rating is the ability to conduct an Instrument Proficiency Check (IPC) for instrument-rated pilots. An IPC serves as a means for maintaining proficiency in instrument flying, and the CFI-I is specifically qualified to administer this check. During the IPC, a CFI-I evaluates the pilot’s ability to perform various instrument flying maneuvers, ensuring that they can safely operate under instrument flight rules.

The other options listed do not align with the privileges granted to a CFI-I. Teaching private pilot aerodynamics falls under the realm of a broader CFI, rather than being specific to the instrument rating. Conducting spin training is not permitted under the CFI-I privileges, as spin training requires specific endorsements and is generally outside the scope of instrument instruction. Reporting aircraft defects to the FAA is a responsibility that may fall on various individuals but is not a specific privilege granted to a CFI-I and typically belongs to the aircraft operator or owner.
