• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

FSXA Starter AMPS issue

The formular is : P (watt) = U (voltage) * I (ampere)

So if you know the amps and normally the voltage you can calculate the performance. And vic versa.

I was always told the best way to remember the formula is to think of James's wife Ivy Watts. James Watts invented the steam engine and it probably the only Scotsman who is mentioned in the SI system.

Seriously though Ed, I know that amperes are the benchmark for normal electrical consumption but If I stop blathering on about watts will you agree that electrical power, which is basically what people have been talking about here, is in Volt-Amperes.

As to Manuals, depends on which ones you have. Most of mine are for military airplanes and they ALL talk about electrical power supply. Power is in W oops! volt-amperes, not amperes. The rate of dissipation of a battery is a product of the voltage output and the current drawn. The battery loses power.

According to the International System of Units... volt is V. I'm not trying to be country specific. Sorry.
 
Roy,

I am concerned that you are introducing a complexity that has no value in the actual discussion. Civilian aircraft typically (I'm certain one can always find an exception) describe the capacity of it's generators/alternators/batteries in amperage and the voltage is defined as being a rated value. There is no indication of watts or volt-amperes in use in the cockpit, only amps.

I can argue semantics with you until the cows come home... but bottom line... the units used in civilian aircraft manuals for describing system performance potential and actual is amperage. Let's leave it at that.
 
The war of letters:)

But was is power? I found there Watt.
But this table is a little weak. There is volt and ohm listed but not ampere.
Okay i will forget everything i learned:banghead:
