NT888G MK2 AUTOPILOT OPERATING MANUAL
1.9 Programmable Automatic Rate of Turn (Section 2.6, 2.32 & 2.35) … (Continued).
(iii)
Use the rotary (+/-) illumination control to select “ ROT ”.
To select required Rate of Turn (6 – 300 deg/min or 0.1 – 5 deg/sec):-
NB. ROT can be expressed (and displayed) in °/min or °/sec as preferred and can be
selected accordingly via the Set Up Menu. (Section 2.6(v) refers).
(iv)
Use the “ LIMITS ” key to display the Limits Menu.
(v)
Use the “ LIMITS ” key again to step through the Menu listing until the
“ ROT°/S ” box is highlighted.
(vi) Use the rotary (+/-) illumination control to select the required ROT in
°/min or °/sec (noting that 6–300°/min = 0.1-5°/sec).
Using the Turn Rate control.
Provided the Rate of Turn function is enabled and specified with a value in °/min or
°/sec, it will automatically control the vessel’s rate of turn during course changes.
When the vessels Rate of Turn is being limited by this function the SET ROT display
box will flash alternating between the value set (i.e.
1°/SEC ) and “ MAX ”. As the
vessel approaches the new set heading and the Rate of Turn decreases, the MAX
display indication will automatically extinguish.
NB. During Track Steering Mode using the HTC sentence (Section 2.9 & 2.38) it is
possible for the Track Controller to override the Autopilot programmed (internal)
value. However, this is only possible up to any maximum permissible ROT value set
within the Autopilot. In this (HTC sentence) Track Steering Mode, it is not possible to
manually Adjust ROT.
1.10 Programmable Automatic Radius of Turn (Section 2.6 & 2.34).
The Autopilot Turn Radius Control function can operate in both the Adaptive and non
Adaptive Modes but it is essential to note that Speed over the Ground (SOG) input
data must be present – without which Radius control will not exist.

the “ TURN TYPE ” box is highlighted.
(iii) Use the rotary (+/-) illumination control to select “RAD”.
To select required Radius of Turn (0.1 - 9.9Nm):-
(iv) Use the “ LIMITS ” key to display the Limits Menu.
(v)
Use the “ LIMITS ” key again to step through the Menu listing until the
“ RAD:nm ” box is highlighted.
