MT Only: Control Points calculations?

[Redcap]

I've hit a tricky issue: Calculating Control Points for a design...

Given: Price figures are not consistently unitised, some are in Mcr, some are in Cr;

Given: Design stage 8.2 (Bridge Control Points) (pp 81 of the MegaTraveller Referee's Manual);

Where:

2 - Control Points

Determine the number of control points required using the
following formula:

CP = (Pr/100000) x TL

CP = Control Polnts Pr = Price. TL = Tech level of the craft.

Section Control Points: Determine the control points required
by each of the 8 following sections:
Hull, Power Supply, Locomotion, Communications, Sensors, Weapons,
Screens, Environment Control.

And:

Noting the Consolidated MegaTraveller Errata (ConsolidatedMegaTravellerErrata v2-21 2-2013.pdf),

Page 81, Step 2, Control Points (correction and additions):
Do not figure control points on hull. When determining control
points required by the power supply, ignore storage batteries.
Storage batteries require no control points.

Is the price in the CP formula in MCr or Cr? Makes one hell of a difference!

Price in Cr. Compare with example craft in IE.

That's what I tought, but I wanted to be sure Ta muchly

Aaaaaaah... NO. No ta, I'd like to keep what little grey matter I have between me ears, not dribbling out of them

 

[Redcap]

Aaaaaand away we go to the headache races! At the bell, it's:

Costs of Power Supply, Locomotion, Communications, Sensors Weapons, Screens, and Environment Control totals Cr. 50524400.00. Thus:

If:
CP=(Pr/100000) x TL;
so:
50524400 / 100000 = 505.244
and as:
505.244 x 14 = 7073.413
thus Control Points = 7073.413

um... that's a BUCKETLOAD of panels in a 20-ton small craft...?!

What did I get wrong?

Wow. Thank you for that. I think?...

I actually did pull out my old RM to follow along and was delighted to find nearly every page of the Craft Design section had pencilled in notes, adjustments, etc. Of course they’re as inscrutable to me now as the original tables they were meant to simplify

Several points:

• even a computer 1 will reduce this by a factor of 10, as it's the multiplier for the panels
• a single HUHD will give you 200 CP...
• even so, it would need quite a lot of panels, but a 50 MCr (before adding the computer and panels) 20 dton small craft must be a quite complex one one, to say the least, so I can find logical for it to need quite a lot of controls (it costs nearly as much as 2 Scouts)

Here are the current calculations to the point of working out control points; if I've messed up, perhaps someone could let me know?

[AnotherDilbert]

Control units are connected to the computer and hence produced control is multiplied by computer CP Multiplier.

A Heads-up Holodisplay produces 200 CP, with a computer m/1 (CPm=10) that becomes 2000 CP, or with a m/1bis (CPm=15) 3000 CP.

So, to produce 7000 CP you need e.g. a comp m1/bis (CPm=15) and 7000 / 15 ≈ 467 CP of controls, e.g. two Heads-up Holodisplays (2×200) and 45 Holographic Linked panels (45×1.5).


You should only have one add-on (HUD, Holodisplay) per crew, so max two?

 

[AnotherDilbert]

You don't need an Intake Compressor with a Fusion Power Plant.

Intake Compressors are for air-breathing engines using hydrocarbon fuels.

 

[AnotherDilbert]

Base price of Small Craft hulls are in kCr, not MCr.

You hull price is 1000 times to high.

 

[AnotherDilbert]

A TL-14 Fusion powe plant produces 3 MW / m³ × scale factor.

Presuming large (14+ m³) plant the scale factor is ×3, so 9 MW / m³.

A 300 MW plant takes 300 / 9 = 33.3 m³ (=kiloliters).

Ah, yes, good point

oops!

 

[AnotherDilbert]

You don't need both HiPen and LowPen Densitrometers. They are the same thing, one is just more sensitive.

A spare system does perhaps good, though.

Ah, I musunderstood the process, then, thanks

Yes, two separate cockpit areas, they're in tandem, so two HUDs. Have you seen the cockpit of a Hind? Two HUDs, same IIRC with the Apache Longbow IIRC, as well, although granted, they don't duplicate the functions, one's an optimised gunsight, the other's a pilot's HUD.

D'OH. No Lanthanum jump grid.

Oh, fiddlesticks. And other imprecations.

Presuming large (14+ m³) plant the scale factor is ×3, so 9 MW / m³.

A 300 MW plant takes 300 / 9 = 33.3 m³ (=kiloliters).

Gagh. Maths

.

Thanks. I'll set to on fixing those TARFUs.

Possibly. The energy budget's low enough for them not to make too much of a diff, anyhow, so I'll hang onto 'em for the moment.

 

[AnotherDilbert]

You have two RFX-14 guns, but only one PD module?

Each gun mount needs a PD module to be PD capable. To have two independent PD capable mounts you need two PD modules.

 

[AnotherDilbert]

Basic Life-Support is ten times too large, see errata.

 

[AnotherDilbert]

Power seems off for Artificial Gravity.

AGrav should be 0.05 MW per m³ Hull, so 0.05 × 270 = 13.5 MW.

 

[AnotherDilbert]

You need more power, the craft consumes ~600 MW.

You need fuel for the power plant.
