Look at the first entry: Closest Point of Approach, page 483 — Page 655, Lesson 759

This is the index of the book — the alphabetical listing of topics and where they appear. I want to walk you through what this tells you, because learning to read an index is part of learning how to use your reference material. Look at the first entry: Closest Point of Approach, page 483. That's a navigation concept — the point where two aircraft, or an aircraft and a ground station, pass nearest to each other. You'll find it in the navigation section. Next, CMU, page 318. That stands for Communications Management Unit — you'll see the full name spelled out a few lines down. This is the box that manages the aircraft's data link communications. It's part of the communications systems, which you'll see listed at page 317. Then CNS/ATM, page 319 — that expands to Communications, Navigation and Surveillance Systems/Air Traffic Management. This is the modern concept of how aircraft communicate, navigate, and are surveilled, integrated with air traffic management. It's a big-picture architecture you'll study in the communications chapter. Now, Coarse Alignment and Coarse Levelling, both on page 237. These are inertial navigation system terms — the initial, rough steps of setting up a gyro platform before fine alignment. They're in the inertial reference section. Cockpit Voice Recorder, page 505 — that's the CVR, the device that records cockpit audio for accident investigation. It's in the recording systems chapter. Then we have Coefficient A, Coefficient B, and Coefficient C, all on page 204. These are the three coefficients used in compass deviation analysis — the mathematical terms that describe how the aircraft's magnetic field distorts the compass. You'll see them in the compass chapter. Coefficients of Expansion, page 26 — that's a physical property of materials, how they expand with temperature. This appears in the early chapters on basic instrument principles. Coloured Arcs, page 9 — these are the coloured markings on an airspeed indicator, like the white arc for flap operating range and the green arc for normal operating range. That's in the flight instruments chapter. Command Attitude Changes, page 343 — this is in the flight director section, referring to the attitude commands the flight director generates for the pilot to follow. Command Speed Limiting, page 413 — that's in the autothrottle or autoflight section, where the system limits the commanded speed. Common Gimbal, page 234 — this is a gyroscopic term, referring to a gimbal arrangement shared between two gyros, often in inertial systems. Compass Deviation, page 119 — the error in the compass caused by the aircraft's own magnetic fields. Compass Liquid, page 122 — the fluid inside the compass that damps oscillation. Compass Needle, page 201 — the magnetic needle itself. Compass Requirements, page 120 — the regulatory and design requirements for compasses. Compass Swing, pages 122 and 201 — the procedure of rotating the aircraft to calibrate the compass against deviation. Compressibility Error, page 44 — the airspeed indication error at high Mach numbers due to air compression. Compression, page 30 — the physical process of air being compressed, relevant to pressure instruments. Computed Information, page 342 — data that is calculated rather than directly measured, used in flight director systems. Computers, page 307 — the general chapter on digital computers in the aircraft. Conditions of Engagement, page 359 — the conditions under which an autopilot system engages or disengages. Cone of Confusion, page 369 — the area directly above a VOR station where the signal is unreliable. Configuration Module, page 97 — a module that stores the aircraft's configuration data. And the last entry is cut off — Configuratio — which is the start of another configuration-related term. So what you're looking at is the map of the book. When you're studying, you use this to find where a topic lives. When you're in the cockpit and you need to recall a specific procedure or limitation, you know exactly which chapter to turn to. This index is your navigation aid through the entire syllabus.
