Help with some failures & altitude

[Snooky]

Hey Pete,

the configuration of our buttons and LEDs is nearly complete, but there are still some LEDs and buttons we don't really know about.

We are still using the Bombardier CRJ-700. I hope you have some ideas where we can read the desired information from FSUIPC. I haven't found anything by now :(

The first 2 LEDs indicate a failure in the generators, LED 1 for generator 1 und LED 2 for generator 2. I searched the offset status pdf but haven't found any offset related to generator or alternator failures.

Then we have 2 LEDs indicating, that crossfeed is inoperable.

You can see that here at the upper middle panel: http://www.digital-aviation.de/site/wp-d_pre1.jpg

There is one LED for the left engine and one for the second engine.

Then again, there are two LEDs named "BTL 1 armed" and "BTL 2 armed". I weren't even able to find out what BTL means. I always got to pages related to some military operations or something.

You can find the LEDs here, right under the engine fire ones: http://flightsimx.s3.amazonaws.com/wp-c2d_day.jpg

For all those LEDs we only need something to read a state like 0 = ok, 1 = failure to control the LEDs.

The last problem I am currently facing is the altitude together with the pull up and ground proximity warning. I tried to light up the LEDs according to the aircraft altitude, but the altitude always seems to be absolute. I would rather like to have the altitude in relation to the ground height. For example, if we are flying to a valley we are 1000 meters high. Now we fly over a mountain, but don't change the absolute altitude. Then we are only like 200 meters high and the ground proximity warning would show up. Is there any offset providing this or can it be calculated from 2 offsets via luascript?

Thanks in advance and keep up the good work!

Unless you are simulating such failures yourself you won't get anything like that. You can build up quite a lot of systems actions using Lua, of course. But FS doesn't in itself. The nearest you'll get to a generator failure is an electrical failure, but by the time you get that you won't see the indications because you'll have no power.

Of course you could light the Generator warning just to indicate they are off when they should be on (e.g. when the engines are 'combusting', if we are talking about engine powered generators).

If you are using a more advanced add-on aircraft then they may simulate subsystems and their failures -- for example the PMDG and Level D airliners do. But then you may not be offered access to their variables as they are in the business of selling the complete system including screen-based panels.

They'll be the extinguisher bottles, to put the fire out. When used you should get a warning as you'd need to refill them on the ground.

Again, FS doesn't simulate the fire control subsystem at all. Only the fire warning when an engine is on fire. There's no extinguishers in FS! I have the complete fire subsystem implemented in my 737NG cockpit, but that's because Project Magenta's "pmSystems" simulates it along with many other subsystems.

The last problem I am currently facing is the altitude together with the pull up and ground proximity warning. I tried to light up the LEDs according to the aircraft altitude, but the altitude always seems to be absolute. I would rather like to have the altitude in relation to the ground height.

You have to subtract the ground altitude, of course. ;-)

But if you are low enough to be within range of the ground radar altitude system on the aircraft then you can read the radar altitude at 31E4. After all, isn't that what the GPWS system uses? Why not use the same?
