This is a Turn and Slip Indicator (also called a Turn and Bank Indicator), a primary flight instrument found in aircraft cockpits. It provides two distinct pieces of information to help pilots maintain control, especially when they cannot see the horizon: 

Key Features

• The Needle (Top): This indicates the direction and rate of turn.
• The markings "L" and "R" stand for Left and Right.
• "360° 2 MIN." means it is calibrated for a standard rate turn. If you align the needle with the white marks (often called "doghouses"), the aircraft will complete a full 360-degree circle in exactly 2 minutes.
• The Inclinometer (Bottom): The curved glass tube with a ball inside is used to check the "quality" or coordination of the turn.
• Ball Centered: The turn is "coordinated" (smooth).
• Ball Off-Center: This indicates a slip or skid, meaning the pilot needs to adjust the rudder. Pilots use the rule of thumb "step on the ball" to remember which rudder pedal to push.
