Pneumatic Turn & Slip Indicator
1: Turn indicator pointer
2: Slip indicator ball
The turn and slip indicator is actually two
instruments in one. The turn portion is a
pointer (1), attached to an air-driven gyro,
which indicates the airplane´s turning rate
in degrees per second. An indicated stan-
dard rate turn should show a turning rate
of 3° per second on the directional gyro.
The slip portion indicates gravitational and centrifugal forces acting on
the airplane. The slip indicator is a simple inclinometer comprised of a
ball contained in a sealed, liquid filled glass tube (2). In a skip or slip,
the rate of turn is too fast or too slow for the angle of bank and will
be indicated by the ball (2) moving from the center to the outside or
inside of the turn.
