Are you now talking about a separate C++ instrument?
Yes.
So the way I see it is I need two C++ modules that need to be created and
hooked into FG.
Right.
How does one do that?
Instrument modules are located in src/Instrumentation.
However I thought JSBSim was just a flight dynamics engine?
Even if these features were added to an aircraft config file FG would still
have to be modified so that instruments can also have their own separate
config files otherwise you end up coding the instrument maths/logic into the

out yet)
How precise is this energy going to be?
Working out gravitational and kinetic energy is trivial; accounting for
energy in the fuel not hard - but I don't think you'll be able to
account for elastic energy stored in the

It's a pilot's tool, not a design thing. It's designed for glider
pilots to show
I'm busy creating a variometer for FlightGear.
My instrument needs to be able to :
1. Display total energy (using some maths I haven't figured
out yet) 2. Play sounds (audio cue) 3. Accept user input to
its 2 knobs and 3 toggle switches.
From what I've seen in FG I would have to

Then only a single include has to be done in an aircraft config file to
load the instrument at the right
