Let me walk you through the key entries so you know what's coming — Page 659, Lesson 780

This is the index of the book — the map of everything we're going to cover. Let me walk you through the key entries so you know what's coming. We start with Logon at page 325, and Longitude at page 2 — that's your geographic coordinate, the east-west position on the globe. Long Range Cruise (LRC) at page 274 — that's the speed setting for maximum fuel efficiency over long distances. You'll see LRC as its abbreviation. Lowest Forecast QNH at page 64 — QNH is the barometric pressure setting that gives you altitude above mean sea level. The lowest forecast value is what you use for terrain clearance planning. Low Height Warning at page 265 — that's your ground proximity alerting system. Lubber Line at page 218 — that's the reference line on a compass or direction indicator that you align with the aircraft's longitudinal axis to read your heading. Now the M section — this is dense. Mach/Airspeed Indicator at page 90, and Machmeter at page 83 — both measure speed relative to the speed of sound. Magnet at page 105 — the fundamental source of the magnetic field. Magnetic Compass at pages 119 and 153 — your basic heading reference. Magnetic Detector Unit at page 211 — that's the sensor that detects the Earth's magnetic field for the compass system. Magnetic Dip at page 111 — the vertical angle of the Earth's magnetic field lines relative to the horizontal. Magnetic Equator at page 120 — where the dip is zero. Magnetic Field at page 105, and Magnetic Flux at page 216 — the field lines themselves. Magnetic Heading Reference System (MHRS) at page 366 — the full system that gives you magnetic heading. Magnetic Materials at page 108 — the materials that interact with magnetic fields. Magnetic Meridian at pages 110 and 201 — the line of constant magnetic heading. Magnetic Variation at pages 110 and 119 — the angular difference between true north and magnetic north. Main Engine Control (MEC) at page 393 — the engine control unit. Main Parameters at page 500 — the key engine readings. Maintenance BITE at page 100 — Built-In Test Equipment for fault detection. Maintenance Reports at page 324. Manoeuvre-Induced Error at pages 16, 42, 61, and 85 — the compass error caused by aircraft acceleration and turning. Manometric at page 366 — relating to pressure measurement. MANUAL at page 241 — the manual mode of operation. And Manual Systems — that's where the entry cuts off. This index is your roadmap. We'll work through each of these topics in order as we go through the book.
