CT Only: Skills that provide levels in other skills

[JEH]

Is there a collated list of these anywhere?

e.g.

Traveller book p29

pilot expertise minus 1 may be used as
ship's boat expertise as applied to interplanetary vessels
under 100 tons; thus, an individual with pilot-3 could also
operate a small craft interplanetary vessel as if he or she had
a skill of ship's boat-2. The reverse is not true.

Book 8 p46

Robotics skill may be used as the next lower level of Computer skill, where needed;
thus Robotics-2 equals Computer-1 . Robotics skill may be used as the same level
of Robot Operation skill.

Also:

LBB4 Page 10:

Battledress expertise may be used as Vacc Suit expertise (...)

LBB5 page12/LBB6, page 17:

(...) Liaison may be used as the equivalent of the next lower level of either streetwise or admin whree necessary (...)

Instead of a hard list, I've always used common sense in regard to this issue. I look at the instances in the game where this happens (Pilot can be used as Ship's Boat at one level lower) as an example. Then, in the game, I may situationally allow skills to be used in different ways based on the game.

For example, let's say the ship goes through a space battle with pirates and comes out a winner against the pirates but dead in space due to a busted jump drive. The ship's engineer--the only character with Engineering skill--was killed during the boarding action.

Do I strand the players out in space or pull of an unbelievable rescue? Nope.

There's no Engineering skill, but maybe the issue can be fixed using Electrical or Mechanical skill. Maybe both skills are needed. I might adjust the target higher than I would if a character with Engineering skill were available.

It's logical that Engineering skill includes some Electrical and Mechanical training, but the game doesn't specify. It's up to the Ref to make a call.



What about ship's sensors? In the basic game, there's no sensor skill (is there one in Book 5...maybe). Let's say the Ref has some pirates hiding just below the surface of a gas giant, laying in wait, to attack some vessel. The PC suspect it's there. How would you roll a sensor check?

I'd use Navigation as the skill. Barring that, I'd use Gunnery (lots of computer sensor use in firing weapons), or Computer, or Forward Observer. Some of these, I might use at a level or two lower.

Off the top of my head, if I needed a sensor task, I'd use:

Navigation - at +2 DM per skill level.

Gunnery - at full skill level. Firing weapons is about using sensors, plotting, and firing weapons.

Forward Observer - at minus one skill level

Computer - at minus two skill level



But, really, it's all up to the Ref and the situation at hand.

Megatraveller Player's Manual, pages 28-29...

You did say "Anywhere...

S4, if you look at the description of Navigation in TTB, it specifically says that the skill covers the operation of the ship's sensors. That only makes sense, as the Navigator needs external data to tell where the ship is in space. Somewhere (Bk5? MT?) there is a Sensor Operation skill introduced, which IIRC serves as Navigation at a 1 skill level penalty. Or Navigation serves as Sensor Ops -1.

It's in MT, and it's Navigation that serves as Sensor Ops at -1. Also reccon (at any level of skill) serves as Sensor Ops 1 (skill level 1, not minus one).

I'm not sure if I missed that sentence or just forgot about it over the years. Thanks for pointing it out.

(FWIW, it also appears in Book 1 (1981)).
