DISPLAYS INDICATIONS
Many of the airplane’s parameters are indicated on one of the displays,
in analogic or digital format.
ANALOGIC INDICATIONS
Analogic indications are provided as pointers moving over a scale,
which may be graduated or not. In both cases, if the pointer indicates a
value out of the normal range for that parameter, both pointer and
scale become amber or red, if the parameter goes deeply into the out
of range area. Pointers are removed if the parameter signal becomes
invalid. For some parameters, scale may also be removed in this
condition. Scale and pointer are not presented for some parameters,
when they are not required, as for EADI chevrons, V

bugs, trend vectors, etc.
DIGITAL INDICATIONS
Digital indications are provided as green characters for normal values.
If the associated parameter goes outside its normal range, digits
become amber, with an amber box surrounding them. Both digits and
box become red if the parameter goes deeply into the out of range
area. If the parameter signal becomes invalid, digits are replaced by
amber dashes, without boxes.
