What is the minimum requirement for current passenger carrying within 90 days?

The minimum requirement for carrying passengers within the preceding 90 days is indeed three takeoffs and landings. This regulation ensures that pilots maintain their proficiency in handling both the takeoff and landing phases of flight, which are critical components of a flight operation, especially when passengers are involved.

Completing three takeoffs and landings allows pilots to demonstrate their ability to effectively manage the aircraft during these essential phases, which is crucial for safety. This requirement is particularly important as it reflects both the practical skills and current experience necessary for safely operating an aircraft with passengers on board.

The other options do not meet the regulatory standards necessary for passenger transport. For example, two takeoffs and landings, or one takeoff and landing, would not provide sufficient demonstration of readiness and proficiency for handling an aircraft with passengers. Therefore, adhering to the requirement of three is vital for ensuring a higher standard of safety in aviation.
