9CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘G’ PART I October 2024 Note.— The term obstacle is used in this CAR solely for the purpose of specifying the charting of objects that are considered a potential hazard to the safe passage of aircraft in the type of operation for which the individual chart series is designed.

An obstacle clearance height for a circling approach is referenced to the aerodrome elevation.

Note 2. — For convenience when both expressions are used they may be written in the form “obstacle clearance altitude/height” and abbreviated “OCA/H”.
