are 90,180,270. When the plane’s speed is greater than 5km/h the heading data comes
from the GPS. When the speed is less than 5Km/H, the heading data comes from the
combination of GPS and internal compass.
5.
The number of satellites that GPS locked.
6.
RSSI, receiver signal strength. If your receiver supports analog RSSI output, AP can read it
from the sensor port and display the value here.
7.
Azimuth angle to the target. Only shown in Auto modes (CIR/ALT/WPT/RTH). When the
target (in WPT mode it's the current way point we are flying to; in RTH mode it's the
home location; in ALT mode it's the cruise direction that AP locked) is to the NORTH of
the plane, the azimuth is 0. When the target is to the WEST of the plane the angle is 270.
8.
Altitude of the target. Only shown in Auto modes. It is the altitude that we are flying to.
In WPT mode it's the altitude of the way point we are flying to; In RTH mode it's the safe
altitude; In ALT mode it's the altitude that we are trying to maintain.
9.
Ground Speed. The unit is km/h or Mile/h.
If AirSpeed sensor is connected you will get 2 readings here. In this case the above one
is air speed reading. The below one is ground speed reading.
10.
Air Speed. Only display when an air-speed sensor is connected to AP.
11.
Throttle indicator. Comparing with the speed bar beside the throttle indicator, a full
length line of the speed bar indicates 100% throttle output. The throttle value of this
screenshot is about 25%.
12.
Relative altitude. Refers to the altitude of the HOME location. It's from the baro-meter.
The unit is in meter or feet.
13.
Climbing rate indicator. A full length line as the altitude bar indicates a 4m/s climbing
rate.
14.
If the climbing rate is greater than 4, A precise number will be displayed (as shown in the
below picture, the climbing rate = 5.7m/s). With 0m/s climbing rate this indicator will be
invisible.
15.
AHL (Artificial Horizon Line). AP estimates the current attitude of the plane and simulates
a horizon line on the screen.
16.
Target indicator. It points to the target (in WPT mode it's the way point we are flying to;
In CIR mode it is the center we are circling, in other modes it's the home location). When
the indicator points to the 12 o’clock, it means the target is in front of the plane. When
the indicator points to 9 o’clock, it means the target is on the left side of the plane and
you need to turn 90 degrees to the left to flying to the target.
17.
Visual Target Object. In WPT mode the system will render this object in the view to
indicate the waypoint you are flying to. In RTH mode this object indicates the HOME
position.
