Hi Dee,

You have to add formation.c in the sources to be compiled (makefile section of your airframe). I also advise you to use the TCAS (http://paparazzi.enac.fr/wiki/MultiUAV#TCAS) in addition to the formation flight control to avoid collision with vertical maneuvers. I really should add some doc in the wiki about this formation flight code. Maybe this summer...

There are many examples in the svn code
for airframes look at
mmlaas_N1.xml
mmlaas_N2.xml
mmlaas_N3.xml
 for flight plans look at
form_follow.xml
form_lead.xml

To see altitudes of planes follow this guide
http://paparazzi.enac.fr/wiki/GCS#Altitude_graph_widget

The flight plans will be shown in the GCS simultaneously you just have to click on the tabs in the notebook section of the GCS

    Dear all, I just barely start working on our multiple UAV project,
    but on Paparazzi website, there is nothing related to the
    formation flight so far. I am looking for some reference that can
    help me start with.
    Here are some general questions after my studyings,
    1. In a general flight plan, in the blocks for the formation
    flight, if we add "call fun=add_slot(#, #, #, #)", "call
    fun="start_formation()", "call fun="stop_formation()", what else
    do we need to add, I try to edit the formation.c and nav.c, but
    there are always "undefined reference to 'add_slot' ", "undefined
    reference to ' start formation' ", and etc kind of errors show up.
    2. Do we have to add anything into each A/C file we are using? and
    how can we set the flight plan for each plane separately showing
    up on the GCS?
    3. I read one paper regarding "Multi-UAV Control with the
    Paparazzi System by Pascal and Gautier", on that GCS, operator is
    able to see the different altitudes for each plane, is there a way
    I can do that too?

    Because I am trying to get the simulation work first, so any help
    and information will be very welcomed. Thanks ahead!
