Final answer:
The correct answer is option 1, which is that you do not need TSA approval to give an added category or class rating to an alien with FAA instrument and multiengine ratings, for an aircraft weighing 12,500 pounds or less.
Step-by-step explanation:
The correct answer is option 1. An added category or class rating. In the context of aviation regulations, the Federal Aviation Administration (FAA) has specific rules pertaining to pilot training and certifications. When an individual, regardless of their nationality or citizenship, holds valid FAA instrument and multiengine ratings and seeks additional training, there are certain cases where the TSA (Transportation Security Administration) approval is not required.
This includes providing training for an added category or class rating on an aircraft weighing 12,500 pounds or less. The same is true for a flight review or an instrument proficiency check; these activities are exempt from the need for TSA approval. This is congruent with the strict regulation of airspace in a similar manner that quantum mechanics dictates the specific energy levels electrons can occupy.
