Starting with the M entries — Page 659, Lesson 781

This is the index of the book — the alphabetical listing of every topic and where it lives in the text. I want to walk you through the entries that fall under M and N, because this tells you exactly what the instrumentation syllabus covers and how the chapters are organized. Starting with the M entries. We have Manual at page 241, and Manual Systems at page 361 — these are separate topics, so don't confuse them. Manual is likely the basic concept of manual control, while Manual Systems is a deeper treatment later in the book. Manufacturing Imperfections appears at pages 142 and 157 — this is about how physical imperfections in instrument construction affect readings, and it's referenced twice, so it's a recurring theme. MAP at pages 286, 288, and 293 — and note the related Map Mode at page 293. MAP here is the navigation display mode that shows your position on a moving map. The Mode Selector at page 286 lets you choose it, and Map Mode is the specific display format. Mask at page 265 — this is a component that blocks or covers part of an instrument display. Maximum Pitch and Bank Angles at page 374 — this is a flight envelope limit, the steepest pitch and bank the aircraft is cleared for. MCDU at page 318 — that's the Multi Control and Display Unit, the main interface for entering flight plan data into the flight management system. MCP Mode Selector Switches at page 368, and MCP Parameter Selection at page 368 — the Mode Control Panel is the autopilot control head, and these entries cover how you select the autopilot modes and set the parameters like speed, heading, and altitude. Mean Sea Level at page 35, abbreviated MSL — this is the reference datum for altitude, the average level of the sea's surface. Measured Ram Rise at page 30 — this is the temperature rise caused by air being compressed as it hits the aircraft at speed. Measurement of Altitude at page 25, and Measurement of Speed at page 25 — these are the two fundamental measurements the instruments perform, and they're introduced together. Memory at page 309 — this is the storage in the flight management computer that holds the navigation database and flight plan. Mercury/levelling Switches at page 177 — these are switches that use mercury or a levelling mechanism to detect attitude. Metering at page 74 — this is the precise measurement of fuel flow in the engine fuel system. Methods of Demagnetization at page 108, and Methods of Magnetization at page 107 — these are the two processes for controlling the magnetism in the compass system, demagnetization removing it and magnetization applying it. Metres at page 2, Miles Per Hour at page 2, Millibar at page 2, Nautical Miles at page 2, and Minutes at page 2 — these are all the units of measurement introduced at the very start of the book, the foundation for everything else. Minimum Speed Reversion at page 414 — this is a flight director or autopilot feature that reverts to a minimum speed reference in certain conditions. MMO at page 83 — that's the Maximum Operating Mach number, the highest Mach speed the aircraft is certified to fly. MMR at page 86 — that's the Multi-Mode Receiver, a navigation receiver that handles multiple signal types. Mode Annunciator at pages 341 and 365 — this is the display that tells you which autopilot or flight director mode is currently active. Mode Controllers at page 341 — these are the devices that let you select and control the autopilot modes. Mode Control Panel (MCP) at page 341 — this is the physical panel on the glareshield where you set the autopilot modes and targets. MODE SELECTOR at page 286 — this is the switch that selects the display mode, like MAP or plan view. Mode Selector Panel at page 239, and Mode Selector Unit at page 240, abbreviated MSU — these are the panels that select the operating mode of the instrument system, like the attitude or heading reference. Modulation Cycle/Frequency Sweep at page 263 — this is the technique used in radio altimeters where the transmitted frequency is swept in a cycle to measure height. Moment of Inertia at page 140 — this is the property of a body that resists changes to its rotation, and it's key to how gyroscopes work. Monitor at page 308 — this is the display screen in the cockpit. MSG at page 278 — this is the message function, likely for crew alerting or communication. Now the N entries. N1 Equalization at page 395, and N1 Mode at page 394 — N1 is the fan speed of the engine, and these cover how the autothrottle manages it, equalization balancing the engines and N1 Mode being the control mode. So that's the full M and N section of the index. Every one of these terms is a topic you'll meet in the chapters, and the page numbers tell you exactly where to find them.
