From this the pilot can tell whether the wings are level and whether the aircraft nose is pointing above or below the horizon. ; Airspeed indicator : Shows the aircraft's speed (usually in knots) relative to the surrounding air. ; Compass : Shows the aircraft's heading relative to magnetic north. ; Direction indicator (also known as Gyrocompass) : Shows the aircraft's heading. ; Turn & bank Indicator or Turn coordinator : Tells if the aircraft is turning and whether it is "in balance" ie, not sideslipping. ; Vertical speed indicator : Shows whether the aircraft is climbing or descending relative to the surrounding air.
