I believe it was more a function of m-drive. A minimum P-plant 2 was needed to
run a maneuver-2. Most ships usually had much higher P-plants.

Two points. First the High Guard sytem was far more abstract than the MT
abstraction. Secondly. Agility and M-drive was almost synonymous in High Guard
which is not true any more (to belabor the point).

Not necessarily. I believe what it meant was an abstract way of representing
evasiveness. Besides if the 6-G P-plant is only putting out 1-G, why not just get
a 1-G drive and use the space for s-thing else.

Why does it have to translate? I think part of our problem is an attempt to High
Guardize, Megatraveeler starship combat system. I wish GDW had totally redone the
system and left no references to High Guard. Basically for all practical
purposes, Megatraveller is an entirely new game from Traveller. In many ways even
the universe is quite different.
>Agility may not exceed maneuver drive rating.
>(No more agility=6 1-G drive ships...)
So??? Were there ever any such ships? High Guard certainly disallowed it and so
does MT.

What you still haven't made clear is how your agility explanation is more
rational. Are the M-drives of a 6-G agility 3 ship pulling actually 9-G
acceleration!!! These eqns are just as arbitrary as the one in MT.

But since there are anti grav modules on board, does the loaded weight really
matter?? I think it was more a question of mass and inertia then weight. However
I do tend to agree with this as it will make all agilities more sensible, just
as adding the mass of armor has.

Why 10?? It is still arbitrary. I would prefer 5, as I personally think that all
ships are too over agile anyway.

Most starships according to Starship Ops manual use overdrives for short periods
routinely to get off planets. Why can't this overdrive ability be considered a
ship's "agility" in combat. It would explain why it is useful in combat. A 6-G
ship all of a sudden pulling 24-G(even for 30 sec) can screw up any one's aim
especially at stellar distances. Assume a 6-G agility 6 ship making 24-G bursts
or 6-G lateral thrusts for 30 sec every 5 minutes can be about 50km from its
predicted location.

Again the question is whether starcraft "agility" has any meaning beyond MT
combat. A grav fighter agility 6 can produce SUSTAINED 6-G turns for 20 min. If
you take my above explanation it can pull up to 24-G for short periods with no
discomfort to its passenger. A Tomcat pilot doing 6-G turns for 20 minutes....!!!
I think COACC is terrible in its most interesting and useful part - the air-space
interface combat involving aircraft and space craft. It is not clearly detailed
and really makes no sense. It makes no real effort to explain any such combat
even though it claims to be basically about this concentrating more on air-air
and air-ground combat. In many ways it is a parallel set of rules to the starship
combat rules.

I presume you mean for COACC. If you intend to give space fighters involved in
MT starship combat agility 9 then there is a major problem. An Agility 9 TL15
fighter(<100t) with Model 9 comp will be impossible to hit except by a spinal PA.
An agility 11 fighter will be totally impossible to hit.
