there is currently no possible entry through papgets. I'm not sure I understand 
what you want exactly. But if you
are ready to develop a standalone application to do it, commnications over the 
Ivy bus would may be enough

For example, if you want to move a waypoint, you will just have to send a 
message like
  joe MOVE_WAYPOINT 3 2 43.123 1.345 250
to the Ivy bus (description of the fields of the message is in conf/conf.xml). 
This message will be handled by the server and forwarded to the aircraft. 
Waypoints ids are available in your var/ACNAME/flight_plan.h

There are examples of connection in C to the Ivy bus in 

If you just need another kind of coordinates, it is maybe simple and I could 
add the feature to the GCS waypoint editor ... Let me know

I would like to be able to allow the operator to enter coordinates as bearing 
and range of a waypoint using the keyboard.  Something like the existing 
waypoint editor, but using different coordinates, and it needs to always be 
at the beginning of the flight plan.  I found some reference to graphical 
objects at, but there's not much 
detail on how to use this, and OCAML is very cryptic to me.

Is there any good documentation on adding functionality (modules?) to the GCS?

I would also be happy to write a separate application in C if necessary, but I 
don't know how to get the data into the GCS.  Can the GCS read data from a file?
