It's a map of the entire book — Page 267, Lesson 364

This is the index of the book, so I want to walk you through what it tells us about the structure of the course. An index is a list of topics and the page numbers where you can find them. It's a map of the entire book. Let's start with the first entry: 3% ERA. That's listed on page 26. ERA stands for En Route Alternate, and the 3% refers to a specific fuel planning rule — you'll learn that in detail later. Next, 123.45 MHz is a radio frequency, found on page 132. That's a specific VHF frequency used for air-to-air communications, often between aircraft. Under the letter A, we have a long list. Abnormal and Emergency Procedures start on page 27. ACAS is the Airborne Collision Avoidance System, on page 81. ACAS RA is the Resolution Advisory — that's the specific instruction the system gives the pilot to avoid a collision — also on page 81. ACAS/TCAS is listed on page 136; TCAS is the Traffic Alert and Collision Avoidance System, which is the specific implementation of ACAS. Acceptance of Dangerous Goods is on page 222 — that covers the rules for carrying hazardous materials. Accident/incident Reporting is on page 101. The Accountable Manager is the person ultimately responsible for the operator's safety, and you'll find that on pages 11 and 24. Additional Crew and Additional Crew Members are on pages 93 and 11 respectively — that covers when you need more than the minimum flight crew. Adequate Aerodrome is a defined term on pages 25 and 40. Adequate ETOPS En Route Alternate Aerodrome is on page 26 — ETOPS stands for Extended-range Twin-engine Operations, and this is a specific type of alternate airport for those flights. ADF is the Automatic Direction Finder, a navigation radio, on page 82. Admission to the Flight Deck is on page 14 — that's about who is allowed in the cockpit. ADS-C is Automatic Dependent Surveillance – Contract, found on pages 133 and 135; that's a way for the aircraft to automatically report its position to air traffic control. Aerodrome Operating Minima are the minimum weather conditions required for takeoff and landing, covered on pages 35, 37, and 38. The Aeroplane Flight Manual (AFM) is the official document for the aircraft, on pages 15 and 93. Aeroplane Lighting is on page 79. Aeroplane Maintenance is on page 29. Aeroplane/STD training — STD is a Synthetic Training Device, a simulator — is on page 96. The Aeroplane Technical Log is the aircraft's maintenance record, on page 103. AFM is the abbreviation for the Aeroplane Flight Manual, on page 93. AGL is Above Ground Level, a measure of altitude, on page 66. AIP is the Aeronautical Information Publication, the official guide to aviation in a country, on page 64. AIP ENR 5.6 is a specific section of that publication, on page 149. Airborne Collision Avoidance System Resolution Advisory is the full name for ACAS RA, on page 47. Aircraft Security Check is on page 197. Finally, the Air Operator’s Certificate (AOC) is the certificate that allows an airline to operate, found on pages 3 and 14. So this index gives you a preview of every major topic we'll cover, from fuel planning and radio frequencies to emergency procedures, navigation systems, and regulatory documents. It's your roadmap for the entire course.
