SLIP-SKID/STANDARD RATE TURN MARKER
DISPLAY
The slip-skid display indicates lateral acceleration of the aircraft. The
slip-skid display replaces the traditional slip ball indicator where the
trapezoid is the equivalent to the ball in a standard turn and bank
indicator. The trapezoidal bottom half of the roll pointer is used as
the slip-skid (lateral acceleration) indicator. When the trapezoid is
displayed offset one width, this is equal to one ball out.
The inverted “V” marks on either side of the center mark of the roll
scale mark the bank angle that must be flown to maintain a
standard rate turn. The position of these “V” marks is a function of
true air speed.
NOTE: The Standard Rate of Turn indicator will not be displayed if
the Air Data, OAT, or TAS has failed or is inoperative.
