Flight Management System (FMS) for the Agusta AW139/AB139 Helicopter
DEFINING A PROCEDURE TURN
The PROCEDURE TURN page, shown in Figure 6--101, is displayed
by pushing the PCDR TURN prompt on the PATTERNS page. The
procedure turn fix is displayed at 1L, the boundary distance at 1R, and
the inbound course at 3L. No changes to this data are permitted. The
outbound leg length defined by distance (3R) or time (2R) and
procedure turn angle (2L) is permitted to be changed. The outbound leg
from HOSSY has a 3.5 NM default leg length while the default
procedure turn angle is L45_.

Defining a Procedure Turn
The default turn angle is changed from the PROCEDURE TURN page.
Enter an angle between 20_ and 90_, prefixed with either an L (left) or
R (right), specifying the turn out direction. In addition, the outbound leg
is permitted to be changed by either specifying the outbound time
(OUTBD TIME) in minutes or outbound distance (OUTBD DIST) in NM.
The controlling entry is in large capital letters. The time or distance
value calculated by the FMS is based on predicted speeds at or into a
procedure turn entry fix (when available), the approach speed (when
available), or a default speed of 120 kts.
After changing any of the parameters, the ACTIVATE prompt at 6R is
displayed. Selecting this prompt redefines the procedure turn.
When the procedure turn is predicted to exceed the boundary distance,
the outbound leg and the turn angle are displayed in reverse video. The
procedure turn is still defined with these values.
