Data Type
1 = ADAHRS data. Other Dynon Avionics formats
look similar, and may be interleaved. This bit tells you
what kind of data will follow.

Data Version
Currently 1. This is the version of the data
represented below and will change if there is a future
version that changes data. Has not changed to date.

System Time
HHMMSSFF, current Zulu time according to
SkyView's internal clock which is synchronized with
GPS time if GPS is available. HH is the hour from 00
to 23. MM is the minute from 00 to 59. SS is the
second from 00 to 59. HHMMSS are '--------' if GPS
time has never been available. FF is the 1/16-second
fraction counter from 00 to 15, and may skip digits if
baud rate is too low to send data at 16Hz.
12
4
Pitch (deg)
+/- then 000 to 900, pitch up or down from level flight
in degrees * 10 (900 = 90°), positive meaning the
aircraft is pitched up. XXXX when not available.
16
5
Roll (deg)
+/- then 0000 to 1800, roll left or right from level flight
in degrees * 10 (1800 = 180°), positive meaning the
aircraft is banked right. XXXXX when not available.
21
3
Magnetic Heading
(deg)
000 to 359 in degrees. XXX when not available.
24
4
Indicated Airspeed
(knots)
0000 to 9999, indicated airspeed in units of knots * 10
(1234 = 123.4 knots). XXXX when not available.
28
6
Pressure Altitude (ft.)
+/- then 00000 to 99999, altitude in units of feet, at a
baro setting of 29.92" Hg, positive meaning altitude is
above sea-level. XXXXXX when not available.
34
4
Turn Rate (deg/s)
+/- then 000 to 999, rate of yaw change in
degrees/second * 10, positive meaning the aircraft is
turning right. XXXX when not available.
38
3
Lateral Accel (g)
+/- then 00 to 99, lateral g’s in units of g * 100 (99 =
0.99 g’s), positive meaning the aircraft is experiencing
leftward lateral acceleration (slip / skid ball is
deflected to the right).
XXX when not available.
41
3
Vertical Accel(g)
+/- then 00 to 99, vertical g’s in units of g * 10 (99 =
9.9 g’s), positive meaning the aircraft is experiencing
upward vertical acceleration.
XXX when not available.
44
2
Angle of Attack (%)
00 to 99, percentage of critical angle of attack. XX
when not available.
46
4
Vertical Speed
(ft./min)
+/- then 000 to 999, feet/minute / 10 (42 = 420 feet
per minute), positive meaning the aircraft is climbing.
XXX when not available.
