Airbus FMGS question
 

Hi all, can anyone answer this?
If you make a lateral revision on the flight plan page, you are presented with various options. One of these option is this;
LL XING / INCR / NO
[ ] / [ ] / [ ]
What on earth does it mean?
Thanks.

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.

( thanks god for FCOM4 :-) )

Not a function I'm likely to use around europe then.

Thanks for the speedy reply.

FCOM 4.3.25 has the answer.
