Instrument meteorological conditions concern visibility, cloud clearance and other relevant weather criteria under the applicable rules.
They describe the weather, not the flight plan alone. An IFR flight can operate in visual conditions, while a pilot encountering unsuitable conditions must act within their qualifications and prescribed procedures.
