This prompt allows you to create a lattitude/lontitude crossing point.
INCR= ranges from 1 to 20°
NO= number of crossing points ( 1 to 99)
This is especially used in polar navigation, atlantic crossings etc for position reporting....
For example you want to have a point every degree from lattitude N48° and you want a total of 10 points
You have to write N48/1/10
Insert it with the R2 key
on flight plan insert it with R6 key
These points are not considered as part of the pilot defined elements /flight plan and the FMGS will erase them once sequenced.
