# Autoflight

Set MCP targets and select autopilot modes for speed, heading, altitude and vertical guidance.

Read active and armed modes separately using the [current autoflight readings](https://www.narev.ai/docs/irl-gym/aircraft/autoflight/controls.md). Do not infer a mode from an undecoded number or a selected button light.

Selected airspeed, heading, altitude and vertical speed have separate observations. The current `cockpit_mcp_and_autopilot` tool provides target-setting actions for altitude, heading, airspeed and vertical speed. Use the units and ranges in the [control catalog](https://www.narev.ai/docs/irl-gym/aircraft/autoflight/controls.md), then verify the selected target.

VNAV behavior depends on BASIC/COMMON, VNAV ALT installation, intermediate restrictions and whether the MCP target is reset before or after top of descent. Use the actual configuration and observed mode. TO/GA roll behavior and GS-before-LOC capture are also configuration-dependent.

## Controls and readings

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