Question 1

How should a pilot determine the direction of bank from an attitude indicator such as the one illustrated?

Accepted Answer

By the relationship of the miniature airplane (C) to the deflected horizon bar (B).

Answer

The attitude indicator displays the aircraft's attitude relative to the natural horizon. The miniature airplane (C) remains fixed relative to the pilot, while the horizon bar (B) moves to represent the actual horizon. Therefore, the direction of bank is determined by observing how the miniature airplane's wings relate to the deflected horizon bar.

Question 2

Deviation in a magnetic compass is caused by the

Accepted Answer

magnetic fields within the aircraft distorting the lines of magnetic force.

Answer

Deviation is a compass error caused by localized magnetic fields within the aircraft itself. These fields originate from electrical currents, ferrous metals, and other magnetic sources in the cockpit and airframe. They distort the Earth's natural magnetic lines of force, causing the compass needle to point slightly away from magnetic north.

Question 3

In the Northern Hemisphere, a magnetic compass will normally indicate initially a turn toward the west if

Accepted Answer

a right turn is entered from a north heading.

Answer

This is an example of Northerly Turning Error (UNOS - Undershoot North, Overshoot South). When turning right from a north heading in the Northern Hemisphere, the magnetic compass's dip errors cause it to initially lag behind the actual turn. This lag makes it appear as if the aircraft is turning towards the west, even though it's turning right (east).

Question 4

In the Northern Hemisphere, a magnetic compass will normally indicate initially a turn toward the east if

Accepted Answer

a left turn is entered from a north heading.

Answer

This is another instance of Northerly Turning Error (UNOS). When entering a left turn from a north heading in the Northern Hemisphere, the magnetic compass's dip errors cause it to initially lag behind the actual turn. This lag makes it appear as if the aircraft is turning towards the east, even though it's turning left (west).

Question 5

In the Northern Hemisphere, a magnetic compass will normally indicate a turn toward the north if

Accepted Answer

an aircraft is accelerated while on an east or west heading.

Answer

This describes Acceleration Error (ANDS - Accelerate North, Decelerate South). When accelerating on an east or west heading in the Northern Hemisphere, the compass card tilts due to inertia and magnetic dip, causing the compass to indicate a turn towards the north. This error is most pronounced on east and west headings.
