Error Coefficient Assessment
（
Attitude measurement error coefficient assessment
）
1.
Attitude measurement error coefficient is an assessment (ECA) of the aircraft attitude as
measured by FY-21AP, FY-31AP or FY-3ZT.
2.
“
0
”
value is normal, maximum value is
“
1000
”
.
3.
The higher the ECA is, the more error in autopilot attitude control will be.
4.
If this coefficient continues to increase to 1,000 in the flight, this indicates the
FY-21AP ,FY-31AP or FY-3ZT do not meet the requirements of automated flight, so flight
control will be transferred back to you (manual flight or RC mode).
5.
This is usually caused by installations that result in high vibrations or shock to the FY-21AP ,
FY-31AP or FY-3ZT. You will need to check or adjust the autopilot installation to reduce
vibration.
l
Display Modes selection
The OSD can be controlled to show different display information via one spare
channel of your radio Rx. There are 5 optional display modes controlled by the different
PWM signals. You can use default mode if you do not want to change the display modes.
How to change the display modes:
You can use a 2-way switch to change the display modes, the PWM signal of the
2-way switch is 900
μ
s
～
1200
μ
s and 1800
μ
s
～
2100
μ
s (in order to describe the
frequency range conveniently , the PWM signal
“
900
μ
s
～
1200
μ
s
”
might be called
“
L
”
for short , and
“
1800
μ
s
～
2100
μ
s
”
might be called
“
H
”
for short. ).
The default mode is
“
A. All information displayed
”
, if you want to change to
“
B.
Default Mode With artificial horizon
”
, just operate as following: first the switch is required
to be played to
“
L
”
, then to
“
H
”
, you have changed the display mode for one time by this.
Save the information after changing. When the OSD powers down and restarts, it will
continue to keep in the display Mode B.
That is to say, you can change the display mode for one time by switching the
“
L
”
to
“
H
”
, the five display modes can be selected by circling in turn like this. (Note: the fifth
display mode is
“
E. Remove All Information
”
)
Mode B is default when a jumper is used in the SW connector and power for the
Hornet-OSD.
l
The modes are shown as below:
Mode A: All Information Displayed
Mode B: Partial Display With Artificial Horizon
Note:
9:Relative altitude (Unit : meter)
A.
When connect with the autopilot or FY-31AP will display the barometer altitude.
B.
When only GPS Receiver is connected to the Hornet, GPS Altitude will be
displayed.
Mode C: Radar Positioning Function
Mode D: Brief Mode
l
Data record of FY-21AP, FY-31AP, FY-3ZT and GPS module
Hornet-OSD can automatically record the information of FY-21AP, FY-31AP, FY-3ZT
or GPS Receiver connected to it via an inserted MICRO SD card.
Data naming:
If no data is received by Hornet OSD, the recorded data is noted at
“
FEIYU***.txt
”
.
(
“
***
”
is a running number from 000 to 999), for example,
“
FEIYU001.txt
”
. If 4 GPS
satellites or more are detected, the file will automatically be renamed after the date and
time of flight (month, day, hour and minute). For example, if the date is Nov 14, eight
minutes pass eight, the name will be
“
11140808.txt
”
.
l
Flight mode
When in the NAV mode (for FY-21AP: Fixed Altitude flying mode; for
FY-3ZT/FY-31AP: Air route fly mode), it will display not only the letter
“
NAV
”
on the
overlay interface, but also the current waypoint every two seconds,
so circulates
.
