Some questions for you. If you don't mind. 1. Have you have added the electric_always_available=1 to you aircraft.cfg? 2. If you haven't added that line, are you having trouble with loss of avionics power? 3. If you haven't added that line AND you aren't having that problem, could you please guide us through what you do from a Cold-n-Dark cockpit to the knob/button settings for maintaining power? Markoz, I have not added anything to the .cfg file and as long as I keep the engines running I have no problem with loss of power. Let's see if I can remember all the steps to get the old bird fired up from the cold.... 1. Cockpit safety check. Hyd pump switches off, gear, gear doors and flaps handles agree - you don't want anything moving until clear. 2. Battery ON - check voltage 3. Fire test APU then start up APU.    Check volts and freqs of APU and close AGR to connect to aircraft busses. Essential power to APU    Note: I do not find a master avionics switch on the pilots overhead??? I wonder how the radios are turned on??? 4. On F/E panel make sure all bleed valves are open - packs off - to get engine start air. Manifold pressure around 40 psi.    If you're not starting engines at this time, turn on packs for air temp control in plane. 5. When clear by ground - HYD B pumps on. Make sure brakes are parked or chocked. 6. Load fuel to desired level. 7. Turn off packs to start engines. 8. As each engine is started, F/E checks engine gen volts and freq [ 115 volts & 400 cycles ]    Select Essential Power to engine one and close MGR to change over power from APU. Do same with each engine. 9. After engine start, turn on A/C packs. That should get you started... :D The more I play with the CS-727 the more fun I have! It's pretty good indeed. If you could have seen the multi-million dollar simulator we had in the 60's you would laugh. Now, today, the simulators we train in are super, but back then the CS-727 would have been heaven. I wish I would have kept my old 727 books. Lou

Hy Sir

I bought CS 727 last week and dispite the beauty of the aircraft it self I beguin To face natural dificulties due the transition of the others airliners of CS and others editors.
The first was about the use of autopilot, that I turn around with more or less dificulty and with precious and of the others members of this forum.
But one remains and caused To send a ticket To CS support that was closed by CS saying that the error was in most cases from users witch don't read the manuals, in most cases is true, because the answers are in these manuals witch in this case don't seam to be true.
So the problem is a well known by you Sir and is about the misterious (for me), loss of the avionics and consequently loss of the autopilot after more or less 8 minutes of shuting down the APU. I have read carefuly your post about this problem with another member and the 3 manuals of CS and did not find why this happens. I followed rigorosly the procedures from you and from the manuals and the end is the same. Solution for me is turn on the APU when it shuts  down et voila I have the avionics and autopilot back. I believe that the error is certanly something that escape from me but I'm shure that the solution is not on the manuals. Oh One more thing: in fact when I beguin a flight from flight 727-100 Cold and Dark Ksea, this problem don't exist, simply don't loose the avionics and the flight goes well.

Can you help about this Sir? Hope not be boaring.
Regards
Antonio
