Which of the following is NOT a requirement to obtain an Instrument Rating?

To obtain an Instrument Rating, you must hold a Private Pilot License, complete ground training, and log a minimum of 50 hours of cross-country flight time as pilot in command. While a Commercial Pilot License can provide additional privileges and certification, it is not a prerequisite for obtaining an Instrument Rating.

The essence of achieving an Instrument Rating is to enhance your flying capabilities under instrument flight rules, which can be pursued by private pilots. Therefore, while option C states that holding a Commercial Pilot License is a requirement, it is not true, making it the correct answer to the question. Understanding this distinction is crucial for aspiring pilots who are working towards their Instrument Rating.
