Definition
The set of immediate actions a pilot takes after unintentionally entering instrument meteorological conditions (cloud, fog, or low visibility) while flying under visual flight rules. The recovery transitions the pilot from outside visual references to controlling the aircraft solely by reference to instruments, then establishes a safe course of action such as climbing to a safe altitude, turning toward known clear air, declaring the situation, and obtaining ATC assistance.
Plain English
What a pilot does the moment they accidentally fly into cloud or poor visibility while flying visually: stop looking outside, fly the instruments, get the aircraft level and under control, and take steps to get back to clear air or to ATC help.
Context Anchor
Seen in instrument training, emergency procedures, and discussions of loss-of-control risk after unexpected entry into cloud or poor visibility.
Derivation
Inadvertent means 'not intended.' Instrument Meteorological Conditions are weather conditions below those required for visual flight. Recovery here keeps its plain meaning: getting back to a safe, controlled state.
Why Pilots Care
A successful recovery prevents spatial disorientation and controlled flight into terrain.
Grounding Statement
Picture flying with the ground in sight, then suddenly entering cloud; the first job is not to find the ground again, but to keep the aircraft controlled using the instruments.
Intuition Check
IIMC recovery does not mean a quick turn back based on what feels right. It means using the instruments and a planned response to keep the aircraft under control after outside visual references are lost.
Example Sentence 1
During training, the instructor had the student practice an IIMC recovery by transitioning to instruments, leveling the wings, and initiating a climb to the minimum safe altitude.
Example Sentence 2
Recurrent training includes practicing IIMC recovery so the maneuver becomes automatic if weather is encountered unexpectedly.
