Data Type
3 = EMS Data. Other Dynon Avionics formats
look similar, and may be interleaved, this bit
indicates what kind of data will follow.

Data Version
Currently 2. This is the version of the data
represented below and will change if there is a
future version that changes data. Data version
changed at SkyView Software v5.1.

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.

Oil Pressure
(PSI)
Varies
(see note 1)
000 to 999 or XXX. Oil pressure in PSI. There
must be a pressure sensor named “OIL” for this
to work. See note 2.

Oil Temp (deg
C)
Varies
(see note 1)
+/- then 000 to 999 or XXX. Oil temperature in
C. There must be a temperature sensor named
“OIL” for this to work. See note 2.

Manifold
Pressure
(inHg)
C37 P26
0 to 600. Manifold Pressure in 0.1 inHg. 299 =
29.9 inHg. There must be a pressure sensor
named “MAP” for this to work. See note 2.

000 to 999. Fuel flow in 1/10
th
Gallons Per Hour.
086 = 8.6 GPH. See note 2.

Fuel Flow 2
(gal/hr.)
C37 P19
000 to 999. Fuel flow in 1/10
th
Gallons Per Hour.
086 = 8.6 GPH. This is usually return flow. See
note 2.

Fuel Pressure
(PSI)
Varies
000 to 999 or XXX. Fuel pressure in 1/10
th
PSI.
274 = 27.4 PSI.
There must be a pressure sensor named
“FUEL” for this to work. See note 2.

Fuel Level L
(gal)
Varies
000 to 999 or XXX. Fuel level in 1/10
th
Gallons.
128 = 12.8 Gallons.
There must be a Level sensor named “LEFT” for
this to work. If there is no “LEFT” OR “RIGHT”
but there is a “MAIN”, this will be MAIN. See
note 2.
