Hi Gautier
Thanks for your explanations. When I configure my flight plan as follows:
<block group="home" key="F8" name="Figure 8 Auto Pitch"
strip_button="Figure 8 Auto Pitch" strip_icon="eight.png">
<eight center="1" radius="nav_radius" turn_around="2" pitch="auto"
throttle="0.75"/>
</block>
I get the error when building:
Unexpected attribute : 'PITCH'
make: *** [ap.ac_h] Error 1
When I read the code in fp_proc.ml I assume the figure eight does not
expect a pitch or throttle attribute. This is my interpretation not
really knowing OCaml.
Where do I need to set the pitch attribute for the figure eight
navigation pattern?
To fly the nav_line navigation pattern in auto pitch mode, how would I
need to change the indicated lines (nav_line.c:81):
NavVerticalAutoThrottleMode(0); /* No pitch */
NavVerticalAltitudeMode(WaypointAlt(l1), 0.);
Best regards,
Reto

Hi,
There is no vmode="pitch".
The possible values for vmode are alt, climb, throttle and glide
(http://paparazzi.enac.fr/wiki/Flight_Plans#Navigation_modes).
Also the vertical mode is independent of the horizontal mode, so you
should
be able to set it with any build-in patterns. This is the case of "eight"
but not "nav_line" which is a custom navigation pattern that sets the
vertical mode by itself (subsystems/navigation/nav_line.c:81).
So, if you want to do altitude control with auto pitch and fixed throttle
with regular patterns: pitch="auto" throttle="xxx" (don't set
vmode="throttle", it would disable the altitude control)

Hi guys
How can be the figure eight of line be flown in vmode auto pitch
(instead of auto throttle)?
I find the according parameters only in the "go", "path" and "circle"
primitive. Not in "eight" nor in "nav_line":
pitch="auto"
throttle="0.75"
vmode="pitch"
By the way, is there a difference between pitch="auto" and
vmode="pitch"?
Cheers,
Reto
