# Reading a bailout plan

import { BailoutScenarios } from "@/components/react/PlannerScreens";
import { ccrDive } from "@/demo/plans";

The **Scenarios** control on the Review step answers one question: if you left
the loop, what would the ascent be? The planner replays the loop plan to the
end of a level, then plans the rest on open circuit on a subset of the gases
you carry, with the same model, gradient factors and stop grid.

You do not pick the failure. The planner bails at the end of every level in
turn, and at the last one tries the whole set of open-circuit-capable gases,
each gas alone, and the combinations between.
[Bailout scenarios](/ccr/bailout) has what limits that list.

## The rows of this dive

55 m for 30 minutes on a 21/35 diluent, a 12 L 21/35 as Diluent + Bailout and
an 11 L 50 % as Bailout with a 21 m switch depth. Every row leaves the loop at
`BAIL @ 55 M · T=33 MIN`, because the dive has one level; a second level adds
a second group.

- **Loop**: the dive as planned, 68 minutes to surface. The rest are read
  against it, and it toggles independently.
- **All bailout gases**: 81 minutes. Open circuit on the 21/35 from 55 m, onto
  the 50 % at 21 m.
- **21/35**: 379 minutes. The whole ascent on the bottom mix, with nothing
  shallow to shorten the stops.
- **50 %**: 77 minutes. Nothing here is breathable at 55 m, so the ascent holds
  its stops on the loop down to 21 m and switches there; a warning in that
  scenario names the wait.

Selecting a row draws it over the profile as a dashed line; the schedule, gas
and tissue views read from it.

## Reading the spread

- The two rows that reach the 50 % surface in 77 and 81 minutes; the one
  without it takes 379. That spread is what the enumeration is for.
- A single-gas row answers whether that cylinder alone would get you out; a
  combination row assumes every cylinder in it is usable.
- Two rows report the 21/35 to 50 % switch at 21 m at error severity in their
  warnings, and both are still planned. See [ICD violations](/gases/icd).

## Next

- [Scrubber tracking](/ccr/scrubber) is the last of the three CCR cards.
- [The gas view](/planning/review-gas) reads a scenario's cylinder figures.
