How to get stairs for the MD-11?

The tfdidesign MD-11 does not include built-in passenger stairs functionality, and users report that opening the aircraft doors at default airports does not automatically trigger the stairs to connect. This issue arises because the default simulator environment does not provide external stair vehicles that can dock with the MD-11's doors. The developer tfdidesign has not released a specific update or addon to address this feature for the MD-11 in either Microsoft Flight Simulator or Prepar3D.

To have passenger stairs appear and connect to the MD-11, users must rely on third-party airport scenery or ground services addons that include interactive stair trucks compatible with the aircraft. Without these external stair vehicles, the default simulator will not display stairs when the MD-11 doors open. This limitation affects users who want to simulate boarding or deplaning procedures realistically with the tfdidesign MD-11, highlighting the need for compatible ground service addons or custom airport environments.
