From the Skills and Tasks section of the Mongoose Traveller Core Rulebook:
Most of the actions undertaken by characters do not require a skill check. A player does not have to roll Athletics to run through a forest, or roll Computers to access information from his ship’s library. Some actions will require the character to have a particular skill, but will still not require a roll. A character with Flyer 0 can fly an air/raft under normal conditions without having to make a roll.
The Referee should only call for checks:
• When the characters are in danger.
• When the task is especially difficult or hazardous.
• When the characters are under the pressure of time.
• When success or failure is especially important or interesting.
