Ships power and Skydemon Logging

[Lerk]

Hi all,

I've been trying to solve an issue with logging engine start times in SkyDemon whilst using PAW connected to ships power.

Previously I used PAW on a powerbank, but now I am using one connected to ships power, I have stumbled on the issue of logging engine start when the PAW is not yet booted.

See discussion on SkyDemon Forum here...

It would appear that the only way to use PAW on ships power is to start the engine and then start flight logging 2-3 minutes later once the PAW has booted.

Are there any other users of installed systems that use SkyDemon that have come up with a better process for startup?

I'm wondering about a pass-through powerbank and separate switch, but I know Anker don't do that and I know PAW issues are frequent when homebrewing power supplies!

Have you seen this?
(which I think is short on output power, 1A)
Or this, but I don't know if it will have the U in UPS

Hi Lerk
I've been using something very similar to this below[note output power] for a year+without any problems [I know I shouldn't have said that!].
Just choose your output plug.
Wired in through a separate CB on the main bus.
Comes on with the Master switch.
All fired up and ready to go before start up.
No problems with starter cranking - modern electronics is incredibly insensitive to voltage drops on the main bus - as this device appears to be.
For a simple avionics setup I can find no reason for an avionics master switch.
 
Good luck
Bob

Hi All,

Good to hear you are getting positive results using such a cheap power supply Ancien. Just a word of warning to others that these type of devices have a poor record as they can be very prone to putting out RFI (interference) all over the place, which can have a seriously negative effect on avionics (not just PilotAware) and comms. There is a reason why Aircraft specific power supplies are expensive - and it’s not to create profit for the makers.

I’m not saying don’t try it - just be aware of the potential issues.

Best Regards

Peter
