2.6 (v) Rate of Turn (ROT) Calibration & Display (°/sec or °/min).
The required ROT operational parameters must be entered into both the Autopilot
SET UP
and
LIMITS
Menus to specify maximum permissible safe Rate of Turn
and normal operating Rate of Turn respectively.
Max. Permissible Safe Rate of Turn & Display Mode (°/min or °/sec):-
It should be noted, that a maximum permissible safe Rate of Turn can – and
should for safety reasons – be entered into the Autopilot
SET
UP
Menu (on
Masters advice) during installation.
This maximum level will be the absolute maximum allowed by the Autopilot even if
a higher ROT is later ordered by the operator or by a Track Control system (and
which, in either case, will result in an Autopilot alarm).
