Re: [Paparazzi-devel] Artificial horizon bank orientation / throttle adjustment

[Stephen Dwyer]

Hello,

Yes, the PFD roll direction issue is a little unintuitive at first, but you have to imagine you are in the aircraft, not looking at the aircraft from the outside (i.e. roll your head to the right, and the horizon now looks to be from upper right to lower left).

For adjusting the cruise throttle, you can use the settings in the GCS notebook to do so (like with any other variable that has the setting available in the settings file). On the Notebook in the GCS, simply go to Settings->control->auto_throttle and adjust the slider for cruise throttle (ranges from 0.0 to 1.0 as a fraction of full throttle). Press the Commit checkmark to send the new value to the aircraft. The number to the left of the slider updates when the change is acknowledged by the aircraft. See the wiki for more details.

Hope that helps.

Thanks,

-Stephen Dwyer

Some people are confused by the pfd as it is a representation of the ground
for an observer inside the plane.
You have to think "left wing looking at the ground", so if the plane is
tilted to the left the slope of the pfd will be to the right...
If you have an IMU you have to follow the instructions here :

However, I noticed when the aircraft is turning  right the AH (artificial
horizon) suggest a bank to the left and vice versa. Has anybody got an
explanation for this ? Is there a way to fix this, eg. have the aircraft
turning right and the AH also banking right ?

example I see the throttle set to 35% and the ac is flying with a certain
airspeed according to throttle setting and attitude, and I decided that I
want to have more or less throttle for whatever reasons. So far I couldn't
find anything, but maybe somebody can point me in the right direction.
