According to EASA regulations, aircraft flying in controlled airspace above FL285 must be FANS-compliant. This regulation aims to ensure the safe and efficient management of air traffic in European skies, promoting enhanced communication, navigation, and surveillance capabilities.

Non-compliance with these specific requirements can result in penalties imposed by regulatory bodies and even jeopardize the ability to operate within European airspace. Airlines and pilots must therefore be aware of and adhere to these regulations to maintain their operational privileges in the European region.

In conclusion, non-compliance with FANS requirements can have significant implications for airlines and pilots. Denied airspace access and specific requirements in certain parts of Europe underscore the importance of adhering to FANS compliance standards. To avoid operational disruptions and ensure the efficient management of air traffic, airlines and pilots must prioritize FANS compliance throughout their operations.
