I don't see 'accuracy' and 'visual detail' as mutually exclusive - you can
have both. I for once am interested in 'realism' in a simulator. An
important part is that the aircraft behaves like an aircraft, rather than
an antigrav vehicle. But part of that is also the visual impression - that
metal surfaces look like metal and clouds look like clouds is for me part
of the immersion experience in the simulation (and yes, I am bugged by the
fact that they behave weird in aerobatics - I just can't fix it...). I
like to look out of the window and watch the terrain and clouds go by.

I realize fully well that there are also people who are mainly interested
in IFR flight who would probably be equally fine with a wireframe terrain
or no terrain at all - but not everyone is like that. Equally well, while
you think it is sufficient that an instrument is readable, I enjoy the
experience more if it looks like a real instrument.

There may not be 'the' real cockpit. The ASK-13 cockpit in Flightgear has
instruments arranged differently from the ASK-13 I have flown in real
life. Should this disagreement in positioning bother me? I have an
altimeter in front of me, a vario, airspeed gauge, they look like they
should, they work - and I just assume it's not the same aircraft and has a
different cockpit arrangement.

And naturally instruments must be functional (I didn't say it anywhere
because it seemed obvious, but instrument fakes, i.e. photo-textures of
gauges which are not operational didn't count as detail in my rating -
they count as 'empty spots').

Short remark: We don't actually disagree here :-) - what I wrote is "which
means either by a single person (or a group of persons with averaging the
opinions), or by a set of sufficiently well defined objective criteria as
stated above"

I looked it up and it got a 3 - seems to be reasonable, even given your
description (it shouldn't get zero because it actually flies - it
shouldn't get 1 because it has usuable gauges, thus maybe it really (=
according to a more involved set of criteria) should be a 2.

So, funnily enough, the rating did produce a reasonable number, even given
the additional info which I could not have known (and indeed did not know
before). Your point being?

It sounds very neat and if a large fraction of aircraft ends up rated that
way, then I'll be the the first to admit that it works better than my
scheme because it contains more information on other aspects.

The main problems I see is:

* it relies on a large number of people (= almost every developer should
do it), otherwise if you create a list and people use it to pick aircraft,
they will pick based on who bothered to self-rate, not based on what is
good

* different people may have different ideas what for example an
'accurately modelled cockpit' is - the same way as right now 'alpha' and
'beta' ratings on the download page mean very different things dependent
on developer

So - let's simply see what happens!

For comparison, here is a draft for how I would rate systems. I think an
important idea is that a model should get full points whenever it is
complete, i.e. implements all there is - so gliders are not punished for
the lack of an engine startup procedure.

"0: doesn't have any instruments, flown with default HUD
   doesn't have controllable systems, engine is always on, no brakes,
flaps etc.

1: has basic set of instruments (altimeter, airspeed, vario,...)
   has basic set of systems, can switch engine on and off, can extend and
retract flaps and brakes

2: has extended set of instruments (navigation, engine gauges,...)
   has a working AP

3: has special instrumentation (basic radar, GPS,...)
   has realistic set of engine start/stop procedures,  has tuned AP

4: has complete set of instrumentation (obviously, gliders don't have much
instrumentation and it's unfair to ask for it, so whenever you have all
instruments and systems an aircraft has in reality, you get this score)
   has realistic emergency procedures (engine flameout in the air, cf. the
Concorde's ram air turbine or the emergency gear extraction of the
IAR-80), models systems beyond those necessary for flight (the F-14b
targeting radar and missiles for example)"
