What is the duration of the grace period for IFR experience?

The duration of the grace period for IFR (Instrument Flight Rules) experience is indeed six months. This means that if a pilot's instrument currency has expired, they have a six-month window to complete the required flight experience to regain that currency without needing to undergo a full instrument proficiency check. During this grace period, pilots can log the necessary flight time under IFR conditions; however, flying with an expired instrument currency beyond the grace period requires retraining or a proficiency check to ensure safety and competency in IFR operations. Understanding this timeframe is essential for maintaining legal flight operations and ensuring that pilots remain proficient in their IFR skills before the window closes.
