System variables
Points P
3
and P
4
can be read in the WCS as system variables during approach.
Changing the WCS between the SAR block and the read operation has no effect on the position values.
$P_APR:
Read P
3
(start point) in WCS
$P_AEP:
Read P
4
(contour start point) in WCS
$P_APDV
=1
If the content of $P_APR and $P_AEP is valid, i.e., if these contain the
position values belonging to the last SAR approach block programmed.
=0
The positions of an older SAR approach block are read.
