Trust belongs to each Settlement and reflects sustained Food supply. Security belongs to a region and reflects the danger of flying cargo there. Unrest links both: it pauses a Settlement's growth and worsens regional ambush risk.

Trust rises only while a commissioned Settlement has supply, and recovers faster the fuller its stock is.

Trust does not fall at or above 75% stock. From full to unrest takes about 44 hours at 70%, 9 hours at 50%, 4 hours 20 minutes at 25%, and 3 hours when empty. Civic Administration multiplies recovery and a UH-1H Food delivery adds a temporary boost.

The clock runs only while someone flies. Spread never pushes a Settlement below unrest and stops as soon as the original source rises above 55% Trust. Recover an Unrest Settlement is the action guide.

Clearing enemy groups raises Security; a wholly unanswered ambush lowers it. Checkpoints create a floor that combat losses cannot cross, and Airspace Command adds 10 floor points everywhere. Every point matters and ambushes disappear only at 100%; Checkpoints alone reach 65%.

Unrest applies a 20-point penalty to ambush rolls in its region without changing the displayed value. Low-Security regions regenerate enemy groups near villages or known sites. Respond to an Ambush covers the player response.
