In the artificial horizon (attitude indicator), what is the gyro attached to? - ANSWER The gyro in
the attitude indicator is mounted rigidly on a horizontal plane.
In the artificial horizon (attitude indicator), what does the horizon bar indicate? - ANSWER The
horizon bar represents the true horizon and is attached to the gyro, remaining in the horizontal
plane as the airplane pitches or banks (rolls) around its lateral or longitudinal axis, indicating the
attitude of the airplane relative to the true horizon.
How can the pilot use the adjustment knob on the artificial horizon (attitude indicator)? -
ANSWER The adjustment knob can be used to move the miniature airplane up or down to align
it with the horizon bar as the pilot sees it from his position.
Normally, the miniature airplane is adjusted so that the wings overlap the horizon bar when the
airplane is in straight and level cruising flight.
In the attitude indicator, what does the movable arrow (perpendicular to the horizon bar)
indicate? - ANSWER Helps pilot see how far they are banking (rolling) one way or another
(10,20,30,90 degrees)

In the attitude indicator, if the horizon indicator line is tilted right, which way are you banking? -
ANSWER If the horizon indicator line is tilted right, you are banking (rolling) left.
*Look at Barron's study guide for different attitude indicators that can appear on tests and
familiarize with bank scale (pg. 147-148)
, What is the only direction seeking flight instrument? - ANSWER Magnetic Compass
On the magnetic compass card, what does 3 and 30 indicate? - ANSWER 3 indicates 30 degrees
30 indicates 300 degrees
The last zero is omitted on each number
What flight instrument is required equipment in all airplanes? - ANSWER Magnetic compass
(despite having many errors)
Magnetic poles vs geographic poles - ANSWER Earth's magnetic field's north and south poles
don't exactly coincide with actual geographic poles. Therefore, the magnetic compass's needles
that seek Earth's magnetic field will not point to true north, but instead to magnetic north.
Furthermore, local magnetic fields from mineral deposits and other conditions may distort
Earth's magnetic field and cause additional errors.
Vertical Card Compass (what's similar and different about it) - ANSWER A magnetic compass
that consists of an azimuth on a vertical card, resembling a heading indicator with a fixed
miniature airplane to accurately present the heading of the aircraft.
Its a newer design that significantly reduces the inherent errors of the older compass models.
Also allows pilot to see the complete 360 degree dial in relation to the airplane heading
Heading Indicator (what it is, its purpose, and advantage) - ANSWER Mechanical (not magnetic)
instrument that backs up and supplements the magnetic compass.
Being mechanical, a heading indicator is not affected by the forces that make the magnetic
compass difficult to interpret precisely.
