ICAO Annex 6 — Page 1, Lesson 9

Welcome to the start of your ATPL studies. I want to walk you through the first chapter of your Operational Procedures book, which is all about ICAO Annex 6. This is the international standard for the operation of aircraft — it's the rulebook that national authorities like the DGCA adopt into their own laws. You need to know this cold. Let's begin with the chapter outline. The chapter is called "ICAO Annex 6", and it opens with an Introduction on page 3. That's where we start. The introduction sets the scene for everything that follows. From there, the chapter moves into Compliance with the Law — that's the section that tells you exactly how an operator and a flight crew must adhere to the rules of the states they operate in. Next is Operational control. This is a key concept. Operational control means the authority and responsibility for starting, conducting, and ending a flight. It sits with the operator, not just the pilot in command, and it's a legal obligation under Annex 6. Then we have Safety. That section covers the operator's duty to establish and maintain a safety management system — a formal way to identify hazards and manage risk. After safety, the chapter addresses Alternate Aerodromes. This is about planning for the unexpected — you must designate an alternate airport to divert to if your destination becomes unavailable, and Annex 6 sets the rules for when and how you choose one. The next section is Flight time. This covers the limits on how many hours a crew member can fly and the mandatory rest periods. These are hard limits designed to prevent fatigue. Then we have Flight Safety and Accident Prevention. This section deals with the operator's programs for reporting hazards, incidents, and accidents, and for actively preventing them from happening. Following that is Maintenance Release. This is the certificate — often called a "release to service" — that confirms an aircraft is airworthy after maintenance. Without it, the aircraft cannot legally fly. Next is Lighting of Aircraft. This section specifies the external lights that must be fitted and when they must be used — things like anti-collision lights, taxi lights, and landing lights. Then, specifically, Navigation Lights. That's a subsection that details the exact colour, position, and intensity of the red, green, and white lights that tell other pilots which way your aircraft is pointing at night. We have a diagram for that. Finally, the chapter ends with Questions on page 7 and Answers on page 8 — those are the practice questions for you to test yourself after we've worked through the material. So, to summarise: this chapter is your foundation. It walks you through the legal and operational framework of international aviation — from how you comply with the law, to who controls the flight, to how you manage safety, plan alternates, manage fatigue, release aircraft for service, and light the aircraft so others can see you. Every one of these sections is examinable and directly applicable to your career as a professional pilot. Let's start with the first section: the Introduction.
