Pilots must hold a specific instrument rating and the aircraft must be appropriately equipped to operate under IFR.
Key Points

- •Requires specific flight instruments and navigation aids to be fitted and serviceable.
- •Involves ATC clearances and separation standards when operating in controlled airspace.
