Don't know if you guy's have tried this but it's worth the shot at it.

Start FSX and then select the Cessna 172, select the airport and parking position you would have selected for your c-130. Set time and season etcetera and continue to load FSX.

Once up and running turn off the engine and all lights and avionics switch. Ensure that it is a complete cold and dark cockpit.

Select your c-130 and then save the flight. Now go through your startup sequence and see if you are able to complete the flight without loosing any power to any of your systems.

Regards,

James.

please please please

my ticket is still pending!

Mr. CS help me!

I had the same problem 'til I searched the dim recesses of my brain from about 40 years ago.  Is the AC Essential bus powered (upper Engineer's panel) and the Flight Director's switch set to normal (AP Panel)?  That should at least solve the power to AP issue.

Two things that can fix this.

First. Create a default C172 flight with everything off except the Avionics Master switch.

Second. Create a keyboard combination for the Avionics Master switch. I use the combination CTRL+SHIFT+A for mine.

I have actually done both of these. But on some planes I want the Avionics Master switch left off.

Also. Pressing CTRL+E (default engine start) also turns on the Avionics Master switch which is why you didn't have the problem when you started it that way.

Hope this helps.

I have the same problem but in my case it is only caused when I open a window that causes the screen to re-write. the culprits seem to be any settings window, open the map, aircraft fuel and payload.

I can restore power to avionics using the avionics master key (Ctrl+Shift+A) which I have assigned.

The same problem/solution also applies for the B727.

Same problem here. This plane has pretty much sat in my hangar since buying it a few years ago.  Reason has been reliability, namely it won't start, but then it will start but there is no way to tell why it did.  Would be good if CS had an answer on this as I am far from alone - i.e. we DO all follow the manual and the tutorials (which are very clearly written) but cold & dark starts continue to be hit or miss.

Got her out yesterday for the first time in ages and managed this time to start her up (odd numbered day of the week perhaps) took off and then had these same avionics failures.  I already have the default C172 with everything off except for avionics set as the default flight and also have a key mapped for master avionics.

Why can't CS even post here to say they have these tickets and are working on it?  With so many other payware aircraft these things often get quickly gang tackled by this kind of group discussion on a forum by the devs and customers together.  Results in nice warm fuzzy feelings all around and one would expect customer goodwill and future sales.  Don't get me wrong, I have the Herc, the 727 and 707 and think they are amongst the best payware, inside and out.  It's just that there is a kind of odd robotic like manner here, not wanting to communicate easily like normal adults do and should.
