TRIAL MENU
Func tion
93 Provides a graphical display of an intended change
of course (CRSE) or speed of Ownship which can then
be assessed in advance, enabling avoiding action to be
planned, when a potential collision exists.
NOTE:
Trial manoeuvre vectors are Relative only.
Se lec tion
94
To select the Trial Manoeuvre menu, carry out the
following:
(1) Highlight the
[TRIAL] box and press any

(3) The cursor is automatically placed in the TRIAL
MANOEUVRE box and the pop-up boxes and the
Pushbutton Selection boxes [3] contain the
following:
(4) If the course (CRSE)/speed/delay (ARPA)
requires adjustment, the implications of the
changes can be viewed quickly on the display as
other target vectors show their new directions
relative to Ownship.
NOTE:
The delay provides a means of delaying the result of the
Trial Manoeuvre for the stipulated period.
(5) To adjust the speed, course or delay press the
appropriate pushbutton and move the trackerball
until the required figure is obtained.
(6) To exit the Trial Manoeuvre facility, position the
cursor in the [TRIAL] box and press any
pushbutton.
95 The course and speed defaults to Ownship’s present
course and speed (i.e. values at the instant ‘trial’ is
activated). The delay (time before the manoeuvre is initiated)
defaults to 10 minutes.
NOTE:
If a previous Trial has not finished, the defaults will not be
used.
De lay
96 The delay may be set to any value, in 1 minute
increments from 1 to 30 minutes. The delay counts
down to zero, from the selected delay period.
97 The delay is adjusted using the trackerball in the
vertical plane whilst pressing the DELAY pushbutton.
At delay time ‘zero’, the trial is cancelled, menu area cleared,
‘TRIAL’ legend cancelled, and the display reverts to normal
operation.
Trial Course/Speed/Time
98 The TRIAL COURSE operates in 5 deg steps, while
the TRIAL SPEED operates in 1 knot increments (0-99
knots). For example, if default Ownship course is 118 deg
true, starboard trial course adjustment selects 123, 128,
133, 138 etc.
99
The trial course and speed are varied by moving the
trackerball in the vertical plane whilst pressing the
COURSE or SPEED pushbutton, as appropriate.
100
The trial manoeuvre functions in True motion TM(T),
Relative motion RM(T) and Relative motion RM(R)
modes. In Relative motion, a TRIAL COURSE LINE radiates
from Ownship to indicate the proposed heading.
101 In True motion TM(T), Ownship’s vector is displayed
along the heading line, then turns onto the TRIAL
COURSE. The DELAY TIME is defined as the time from the
initialisation of the delay period to the time that Ownship has
completed the manoeuvre.
102
Collision targets in Trial mode are designated with a
triangle symbol.
