I appologize if I missed this, but I didn't see it when I RTFM'd. I am setting up the ardupilot for an airplane. I have an airspeed sensor, a magnetometer, and a XBee downlink. All using DIY Drones parts, set up as shown on the wiki page. I have not flown, I am bench testing.
What do the symbols in the upper left of the hud represent;
1: The five small vertical bars with the center one slightly larger
2: The three horizontal bars with a green T below one of the bars.
3: On the top down map, the colored lines; red is aircraft heading, yellow is commanded nav path? Green is ? Black is current ground path?
4: Is there any set up needed to use the magnetometer? If I use the declination for my area my heading doesn't line up with reference directions (Off by ~10deg when pointing north, more as pointed south) Is there a calibration procedure, or will it autocalibrate as it begins to fly/cover ground? I took the setup for a walk, including some turns, but it did not change the reading.
Thank you for your time.

hi.
1. is crosstrack error.
2. turn rate
3. green is nav path
black is course over ground
red is current heading
orange is path to next wp
4. in planes a mag is optional, some uses do find it better as it reduces the yaw lag while turning. however is not required. on a quad a mag is required. when using a mag you set the current magnetic declination offset, the rest is auto calibrated.
