c) Three different instrument approach procedures using navigation aids and equipment.

The applicant shall have demonstrated a level of knowledge appropriate to the privilege granted to the holder of an instrument rating in the following subjects:
(1) Rules and regulations relevant to flight under IFR, use of aeronautical documentation such as AIP, NOTAM;
(2) IFR air traffic management procedures, radiotelephony procedures and phraseology as applied to operations under IFR;
(3) Use, limitation and serviceability of avionics and instruments practices and procedures in the event of malfunctions of various flight instruments;

The applicant for instrument rating shall have completed not less than 3 hours of instrument training flight time within the preceding 60 days, or the applicant has completed CAA approved training program specifically designed for qualifying such applicants. The applicant flight check shall be conducted in accordance with the requirements prescribed by the Article27, Article 32, Article 44 and Article 49 respectively.

Pilots-aircraft or helicopter may engage in operations under IFR only after being granted the instrument rating.
