relation to the actual heading direction of the aircraft. When setting the gyroscopic heading indicator to agree with the magnetic compass, use the average indication between the swings. The Vertical Card Magnetic Compass The vertical card magnetic compass eliminates some ... errors and confusion encountered with the magnetic compass. The dial of this compass is graduated with letters representing the cardinal directions, numbers every 30°, and tick marks every 5°. The dial is rotated by a set of gears from…

The Vertical Card Magnetic Compass The floating magnet type of compass ... 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…

Magnetic Compass Overview A magnet is a piece of material, usually a metal containing iron, which attracts and holds lines of magnetic flux. Regardless of size, every magnet has two poles: a north pole and a south pole. When ... unlike poles attract each other and like poles repel. Figure 5-15. Color codes for an ASI. An aircraft magnetic compass, such as the one in Figure 5-16, has two small magnets attached to a metal float sealed inside…

Magnetic Compass Induced Errors The magnetic compass is the simplest instrument in the panel, but it is subject to a number of errors that must be considered. Variation The Earth rotates about its geographic axis; maps and charts are drawn ... geographic poles. Directions measured from the geographic poles are called true directions. The magnetic North Pole to which the magnetic compass points is not collocated with the geographic North Pole, but is some 1,300 miles away; directions measured from…

Magnetic Compass One of the oldest and simplest instruments for indicating direction is the magnetic compass. It is also ... placed in the field of another, the unlike poles attract each other, and like poles repel. An aircraft magnetic compass, such as the one in Figure 8-32, has two small magnets attached to a metal float sealed inside…

subtraction, as shown, to magnetic indications to arrive at a true geographic direction. Another peculiarity exists with the magnetic compass that is not dip error. Look again at the magnetic compass in Figure 10-79. If flying north or toward ... direction oriented as they are on an aeronautical chart or a hand-held compass. Vertical Magnetic Compass Solutions to the shortcomings of the simple magnetic compass described above have been engineered. The vertical magnetic compass is a variation…
