# Contingency

import { ContingencyCard } from "@/components/react/PlannerSettingsScreens";

An overrun is the dive you did not plan: the bottom held a few minutes longer,
or a few metres deeper, than the plan says. The **Contingency** card re-plans
the dive for each overrun you name. The primary schedule never moves; every
overrun is computed beside it.

## The fields

- **Contingency**: on or off. A plan arrives with it on and two rows in place,
  +5 min / +3 m and +5 min / +6 m. Switch it off and it stays off for that
  plan, and no overrun is computed.
- **+min over**: minutes added to the planned bottom time.
- **+m over**: metres added to the planned depth.

Each row carries its own remove control, and a new row starts at
+5 min / +3 m. The planner holds at most six rows; at six the add control is
disabled and says so. A row with both fields at zero computes nothing.

## In the Review step

Each row appears in the [Review step's](/planning/reviewing) scenario picker as
its own group, labelled by its numbers: "+5 min / +3 m". On a closed-circuit
plan every overrun carries a full [bailout set](/ccr/bailout) of its own, which
answers the question the card exists for: if the dive runs over *and* you then
have to bail, is the bailout gas still enough? On open circuit each overrun
carries its own set of lost-deco-gas ascents instead.

Read an overrun's figures from the group's own row, named **Loop +5 min /
+3 m** on a rebreather and **OC +5 min / +3 m** on open circuit, then select
the ascents grouped under it, each named with the overrun's numbers before its
own; every one is a complete plan with its own schedule, gas figures and
warnings.

## Next

[Descent and ascent rates](/planning/rates) is the next card. For what the
scenario picker shows on the dive as planned, see
[the Review step](/planning/reviewing).
