CT Only: Calculating Agility in CT

[Silverhawk]

Okay you would think that having played Traveller on and off for as long as I have that I would remember how to calculate agility properly. But I seem to have done something silly and I am getting impossible numbers.

Can someone refresh me on how the calculation works in CT

Thanks

This is the section of Book 5 (1980)
Agility: Energy points remaining after weapons, screens, and computers have
been installed may be applied toward the ship's agility rating. Divide the remaining
energy points by 0.01M; the result is the number of agility points the ship has.
Drop all fractional points. Agility is the ability of a ship to make violent maneuvers
and take evasive action while engaging hostile targets. A ship's agility rating may
never exceed its maneuver drive rating. For each power plant hit received in combat
(cumulative) the ship's agility rating is reduced by one.

A ship may voluntarily refrain from using any weapons or screens (computers
may still be used) which require energy points and receive an emergency agility
rating (for that combat round only) equal to its current maneuver-drive rating or
power plant rating (whichever is lower).

That said, one needs more info to help.

Basically, if you can power the M-drive fully agility is M-number.

If you use some of that power for something else, reduce agility proportionally (drop fractions).

Easiest way to think about how to calculate Agility is ... 1% of tonnage in EP per point of Agility.

Example:
100 ton starship
1% of 100 tons is 1 EP.

• Agility=1 requires 1 EP.
• Agility=2 requires 2 EP.
• Agility=3 requires 3 EP.
• Agility=4 requires 4 EP.
• Agility=5 requires 5 EP.
• Agility=6 requires 6 EP.

Scale upwards proportionately for larger hull sizes.
400 ton starship requires 20 EP allocated to maneuver drive to achieve Agility=5.

Weapons, computers and screens will require additional EP on top of that amount.

Easiest way to determine Agility is to take total EP generated by the power plant, subtract the EP spent on weapons, screens and computers (and anything else, if any) to find the "remaining" EP that can be dedicated to the maneuver drive. Whatever that remainder is ... divide that remaining EP by 1% of the hull tonnage and drop fractions.

Example:

• 400 ton starship
• Maneuver-4, Power Plant-4 (16EP generation)
• Pulse Laser (1EP) and Computer Model/4 (2EP)
• 16-3=13
• 13/4=3.25
• Agility=3 with +1EP to spare (3*4+1=13+3=16)

Once you get used to "doing the math in your head" it only becomes something that needs a calculator when dealing with tonnages that are not divisible by 10 or 100.

Thanks all. I think I had a number or two reversed on the page and got super large number that even when you use the cut off for size of the M-drive just didn't seem right.
