What is required for a crew of two to legally fly an aeroplane?

For a crew of two to legally operate an aeroplane, the completion of ground and flight training, as well as passing the IATRA (Instrument Rating Test) is essential. This training ensures that both pilots are equipped with the necessary skills and knowledge to handle various situations that may arise during flight, including the instruments required for navigation and safety protocols.

The IATRA certification demonstrates that the pilots have met the standards set by the aviation authority, confirming their competency in operating the aircraft, especially in more complex environments, such as those that require instrument navigation. This regulatory requirement is crucial for maintaining safety in aviation, as it ensures that both members of the crew are adequately trained to manage the operation of the aeroplane effectively.

While factors like completion of solo flight training, certification from a flight school, and advanced navigational training are important in a pilot's overall development, they do not specifically address the legal requirements for a crew of two operating an aeroplane together in a certified manner.
