* Departure frequency.
* Ground frequency.

## <mark style="color:$warning;">Smart formatting</mark>

The tool formats some common inputs when you move to the next field:

| Input                         | Result    |
| ----------------------------- | --------- |
| `050`                         | `FL050`   |
| `350`                         | `FL350`   |
| `5000`                        | `5000FT`  |
| `119625` in a frequency field | `119.625` |

## <mark style="color:$warning;">Taxi highlighting</mark>

Taxi mode visually distinguishes higher-attention instructions:

* Runway crossing instructions are shown as red chips.
* Hold-short instructions are shown as amber chips.
* Follow-the-green and other airport-specific tokens use distinct colors where available.

## <mark style="color:$warning;">Storage</mark>

Structured clearance, scratchpad text, and draw mode data are saved locally. Taxi route data is transient and can be cleared when complete.
