Interpret readings on a turn-and-slip indicator.

Interpretation should include the following concepts:

• The slip/skid indicator is the horizontal line below the roll pointer.
• Like a ball in a turn-and-slip indicator, a bar width off center is equal to one ball width displacement.
• The turn-rate indicator is typically found directly above the rotating compass card.
• Tick marks to the left and right of the lubber line denote the turn (standard rate vs. half-standard rate).
• Typically denoted by a trend line, if the trend vector is extended to the second tick mark, the aircraft is in a standard-rate turn.
• An explanation of the difference between a turn-and-slip indicator and a turn coordinator.
