A “Flight School” is an FAA certificated (approved) pilot school. This is a business that trains non-pilots for an FAA License. There is no flight school at the airpark.
Obtaining an FAA license is also called Primary Flight Instruction. It includes classroom training, ground instruction, flight instruction leading to a solo flight and then allowing the student pilot to accumulate the required 40 hours needed before testing and obtaining an FAA License.
Testimony in the 2019 FAA investigation confirms that Primary Flight Instruction is conducted at the airpark.
