# Fuel

Manage fuel pump and crossfeed selections, and read switch states and pressure warnings. The MCP group also includes APU controls.

The fuel system provides six pump-position indications and corresponding toggle actions. Use the selected fuel configuration and actual loading. Where center-pump automatic shutdown is fitted, switch selection and pump operation must be distinguished.

## Controls and readings

See [the current controls and readings](https://www.narev.ai/docs/irl-gym/aircraft/fuel/controls.md) for this system.
