# Airflow chart compatibility reference for Astro Private Cloud

Astro Private Cloud (APC) Deployments use the [Astronomer-distributed Helm chart for Apache Airflow](https://github.com/astronomer/airflow-chart). A Deployment's Airflow chart defines how a Deployment interacts with other components in your cluster.

Use the following table to see the Airflow Helm chart version for each supported version of APC. To view the Airflow Helm chart for an unsupported version of APC, open the default Astronomer Helm chart in the [`astronomer/astronomer` repository](https://github.com/astronomer/astronome/blob/release-2.0/charts/astronomer/values.yaml) and select the **Tag** that corresponds to the unsupported version. The value of `airflowChartVersion` is the Airflow Helm chart version.
