What is the "grace period" for instrument currency after 6 months of being current?

The concept of the "grace period" for instrument currency is crucial for ensuring that pilots maintain their proficiency and safety in flying under instrument flight rules. When a pilot has been instrument current but then allows their currency to lapse, the regulations specify that they have another 6 months during which they can regain their instrument currency by flying with a safety pilot.

This allows a pilot who has not been actively flying under instrument conditions to have the support and oversight of a safety pilot, who must also be instrument-rated. This arrangement helps reinforce the pilot's skills through practice and feedback in a controlled environment, ensuring they are well-prepared to meet the demands of flying solely by instruments again.

After that 6-month grace period, if the pilot does not complete the required flight experience or training to regain currency, they would need to meet the full requirements for obtaining their instrument rating again, which involves more comprehensive training and evaluation.
