The position of correctors should be recorded in the compass book and on deviation cards. To find the true course when the compass course is known: Compass course ± deviation = magnetic course ± variation = true course, Compass tends to dip toward the magnetic pole, most dominant as latitude increases, The lines of magnetic flux leave the Earth at the magnetic North Pole and enter at the magnetic South Pole, pronouncing magnetic dip near the poles, At both locations, the lines are perpendicular to the Earth's surface, At the magnetic equator, which is roughly halfway between the poles, the lines are parallel with the surface, Within 300 miles of the poles, the instrument is unreliable due to extreme errors, The south end of the compass is therefore weighted to minimize this error, The magnets in a compass align with this field; near the poles, they dip or tilt the float and card, A small dip-compensating weight balances the float, so it stays relatively level when operating in the middle latitudes of the northern hemisphere, To counter this, the pivot point on which the bar magnet swings is deliberately placed at a position other than the magnet's, The pull of the vertical component of the Earth's magnetic field causes northerly turning error, which is apparent on a heading of north or south, When an aircraft flying on a heading of North makes a turn toward East, the aircraft banks to the right and the compass card tilts to the right, The vertical component of the Earth's magnetic field pulls the north-seeking end of the magnet to the right, and the float rotates, causing the card to rotate toward West, the direction opposite the direction the turn is made, When turning from a northerly heading, the compass will initially turn the opposite direction and catch up by due East/West [, When turning from a southerly heading, the compass will indicate a turn in the proper direction but will lead the actual heading, slowing down by due East/West [, The rule for this error is: when starting a turn from a northerly heading, the compass indication lags behind the turn, The rule for this error is: When starting a turn from a southerly heading, the compass indication leads the turn, If the turn is made from north to West, the aircraft banks to the left, and the compass card will tilt down on the left side, The magnetic field pulls on the end of the magnet that causes the card to rotate toward East, This indication is again opposite to the direction the turn is made, When an aircraft is flying on a heading of south and begins a turn toward East, the Earth's magnetic field pulls on the end of the magnet that rotates the card toward East, the same direction the turn is made, If the turn is made from south toward West, the magnetic pull starts the card rotating toward West-again, in the same direction the turn is being made, New heading: roll-out heading ± latitude - half the bank angle, The dip-correction weight causes the end of the float and card marked N (the south-seeking end) to be heavier than the opposite end, When the aircraft is flying at a constant speed on a heading of East or West, the float and card is level, When the aircraft accelerates on a heading of East/West, inertia causes the weight to lag, and the card rotates toward North [, When the aircraft decelerates on a heading of East/West, inertia causes the weight to move ahead, and the card rotates toward South [, The airspeed changes that are needed to make this noticeable are infrequent, As soon as the speed of the aircraft stabilizes, the card swings back to its East indication, Fluid fills the compass body, which provides damping, thereby decreasing unwanted oscillations due to turbulence of the magnet and float, Fluid should therefore fill the compass, and no air bubbles or compass fluid discoloration should be present, The clear compass face (window) has on it a vertical line called a "LUBBER LINE" so that the pilot can use it as a datum to set the required heading, Oscillation is a combination of all of the other errors, and it results in the compass card swinging back and forth around the heading flown, Turbulence causes the compass to "bounce" or move in the container, When setting the gyroscopic heading indicator to agree with the magnetic compass, use the average indication between the swings, The floating magnet type of compass not only has all the errors just described but also lends itself to confused reading, It is easy to begin a turn in the wrong direction because its card appears backward, East is on what the pilot would expect to be the West side, The vertical card magnetic compass eliminates some of the errors and confusion, The dial of this compass is graduated with letters representing the cardinal directions, numbers every 30° and marks every 5°, A set of gears rotates the dial from the shaft-mounted magnet, and the nose of the symbolic airplane on the instrument glass represents the lubber line for reading the heading of the aircraft from the dial, Eddy currents induced into an aluminum-damping cup damp oscillation of the magnet, As mentioned earlier, the lines of flux in the Earth's magnetic field have two basic characteristics: a magnet aligns with these lines of flux, and an electrical current is induced or generated in any wire crossed by them, The flux-gate compass that drives slaved gyros uses the characteristic of current induction, The flux valve is a small, segmented ring made of soft iron that readily accepts lines of magnetic flux, An electrical coil is wound around each of the three legs to accept the current induced in this ring by the Earth's magnetic field, A coil wound around the iron spacer in the center of the frame has 400-Hz alternating current (A.C.) flowing through it, During the times when this current reaches its peak, twice during each cycle, so much magnetism is produced by this coil that the frame cannot accept the lines of flux from the Earth's field, But as the current reverses between the peaks, it demagnetizes the frame so it can accept the flux from the Earth's field, As this flux cuts across the windings in the three coils, it causes current to flow in them, These three coils connect in such a way that the current flowing in them changes as the aircraft heading changes, The three coils connect to three similar but smaller coils in a synchro inside the instrument case, The synchro rotates the dial of a Radio Magnetic Indicator (RMI) or a horizontal situation indicator (HSI), Made of soft iron that readily accepts a line of flux, A coil wound around the iron spacer has 400-Hz AC flowing through it, As current peaks, twice during each cycle, there is so much magnetism that the frame cannot accept the lines of flux, but as the current reverses, it demagnetizes to accept more, The three coils connect to three similar but smaller coils in a synchro inside case, The synchro rotated the dial of a Radio Magnetic Indicator (RMI or an HSI), Magnetic direction indicators (of which a magnetic compass satisfies) are required by, Full of fluid; card in place and indicating a correct heading, Compass card installed (does not need to be filled out), A compass swing must be performed whenever any ferrous component of the system (i.e. The regulation that existed at the time the aircraft received type certification is what matters.
