Tho I can input the coordinates just like WarriorX's howto says, I have a question related to that.
I input coordinates prosecute my attack, kill the target and contact JTAC again.
In the process, making SPI and CDU comes up with markpoint Z. After that the CDU no longer accepts LL input (since markpoint Z is reserved). What i then do is switch to steerpoint page move the steerpoint and switch back to WP page. How you guys do it?
