eric737 Posted July 13, 2014 Report Share Posted July 13, 2014 Hi,I am trying to get the engine start working with FSUIPC , however when I connect starter 1 to the assigned switch it works but light up via fuel selector does not work ? When I connect the same to autostart 1 it works but there is an annoying grinding added to it , any idea which way would be the correct way to connect my overhead switches to FSX ?

Thomas Richter Posted July 13, 2014 Report Share Posted July 13, 2014 Hi, Fuel Selector is not the way to feed the engine with fuel, you need to use the Fuel Cutoff lever. In FS it is the Offset for Fuel Mixture. 0890 2 Engine 1 Mixture lever, 0 – 16384 0928 2 Engine 2 Mixture lever, 0 – 16384 Link to comment Share on other sites More sharing options...
eric737 Posted July 14, 2014 Author Report Share Posted July 14, 2014 HI , thanks but I do use the fuel cutoff to get the engine started at the right N2 speed , which as I said will do the trick but still have this grinding noise with it , so what is the correct setting in FSIUP for engine start?

Pete Dowson Posted July 21, 2014 Report Share Posted July 21, 2014 HI , thanks but I do use the fuel cutoff to get the engine started at the right N2 speed , which as I said will do the trick but still have this grinding noise with it , so what is the correct setting in FSIUP for engine start? What program is making a "grinding" noise? Merely enabling the fuel to flow at the correct N2% value is the way to start a jet engine, then you release the starter back to "off" when the EGT has peaked (or simply watch the combustion flag in FSUIPC offsets). There's no other 'correct' way. Pete Link to comment Share on other sites More sharing options...
eric737 Posted July 23, 2014 Author Report Share Posted July 23, 2014 Thanks Pete If I select engine autostart 1 in FSUIPC to my starter switches I get this rumbling/grinding noise , when I select all eng autostart then I get no noise , I know how to start engines, that is not the problem it is that noise and consequently failure of some systems after 15 min when finally the noise stops? I use a normal i.o.card to do the functions via numbered switches in FSIUPC cheers Eric Link to comment Share on other sites More sharing options...

You are using the additional FSUIPC separate engine autostart controls? I thought you were talking about operating things yourself. There are no sounds produced by FSUIPC. I really don't know what is going on with your system, but here's exactly what that autostart system does: 1. Switches the battery on (offset 281C) 2. Switches the avionics on (offset 2E80) 3. Selects appropriate fuel tank(s) (offsets 3880, 37C0, 3700, 3640 according to engine number) 4. Turns the appropriate fuel pump on (bit in offset 3125) 5. Turns the starter switch to start, according to engine type (jet/prop) and engine number (offsets 0892, 092A, 09C2, 0A5A) After a delay (20 seconds for jets, 2 for props) 6. Sets props to full (offsets 088E, 0926, 09BE, 0A56) 7. Sets fuel rich for all but turbos, which start with about 40% (offsets 0890, 0928, 09C0, 0A58) Waits to see engine combustion flag (offsets 0894, 092C, 09C4, 0A5C), then: 8. Returns starter switch to "Gen", "Both" or "off" depending on engine type (same offsets as before) 7. Switches engine generator on (offsets 3B78, 3AB8, 39F8, 3938) And that's it. As you can see it is a truly lazy way of preparing the cockpit for flight! I can only think that the sound you are hearing is from one of the subsystems and is an effect built into your aircraft, or maybe supplied by another app, such as pmSounds. I know, for instance, that pmSounds produces an electrical fan/motor type noise when you have the avionics turned on. If this is it and it goes off after 15 minutes it seems you are turning whatever subsystem it is back off. If you don't like the sound, try turning it off at source.

Aviation BoSs Posted July 23, 2014 Report Share Posted July 23, 2014 Hello .. Excuse me if i'm posting in wrong section How I can read PMDG737NGX HDG bug value by visual basic ? I need a basic example Link to comment Share on other sites More sharing options...
Pete Dowson Posted July 23, 2014 Report Share Posted July 23, 2014 Excuse me if i'm posting in wrong section You aren't in the wrong 'section', but yours is a new question and you are appending it to an existing thread about a different matter. I'll answer it here, but please, when you have a NEW question please start a new topic. You'll see the button to do this. Then entitle the topic with something relevant. How I can read PMDG737NGX HDG bug value by visual basic ? I need a basic example I'm afraid I don't use VB so I can't tell you myself. Have you looked at example code in the FSUIPC SDK? It can't be too hard. It might be even easier if you use Paul Henty's .Net interface (see separate subforum above).. If you really want more help then you need a topic entitled with a question which will attract the folks who can help. Pete 1 Link to comment Share on other sites More sharing options...
eric737 Posted July 23, 2014 Author Report Share Posted July 23, 2014 Thanks again Pete , I am trying simply to connect my 2 overhead switches via FSUIPC to starter 1 and starter 2 , as I have a console with fuel shutoff I use them to lightup the engine after the correct N2 , when I use the same switch to all eng start or CTRL+E no noise what so ever? I only use the default 737 for the action? very confusing? Need to make atrip to me to sort it (Cheshire )????? Regards Eric Link to comment Share on other sites More sharing options...

I only use the default 737 for the action? Why on Earth do you want to use an autostart action, which is designed for folks with no switches, just a spare button or keypress, when you have separate switches? You want to use the"StarterN set" control (N is the engine number), not autostart! The parameter for that is 0 for off, 1 for ground (=start), 2 for "gen" (not a proper 737 setting for the starter switch, but FS doesn't truly simulate a 737 in this area).

(N=Engine number)! If you know how to do all this using keyboard or mouse on the screen cockpit, you can easily find the right controls by using FSUIPC's logging. Just enable Event logging. You can even see it in real time on screen if you (temporarily) run FS in Windowed mode and enable FSUIPC's console log. Pete Link to comment Share on other sites More sharing options...

eric737 Posted July 24, 2014 Author Report Share Posted July 24, 2014 Pete I have now mostly sorted it , the only thing I needed as my fuelshutoff's are not recognized by FSIUPC to assign another switch to mixture , now the strange thing is that the fuel shutoffs seem to work , maybe I leave things as they are at least no more noise from any grinder, very much appreciated and kindest regards Eric Link to comment Share on other sites More sharing options...
