Instrument rating refers to the qualifications that a pilot must have in order to fly under IFR (Instrument Flight Rules). It requires additional training and instruction beyond what is required for a Private Pilot certificate or Commercial Pilot certificate, including rules and procedures specific to instrument flying, additional instruction in meteorology, and more intensive training in flight solely by reference to instruments. For most private pilots, the most significant value of flying under IFR is the ability to fly in instrument meteorological conditions (such as inside clouds).
You Must Be Atleast 17 Years Of Age And Hold at least a Private Pilot License. A Medical Certificate.
