Hi PX4 community,

> **Related context:** this question follows the broader [generic airship support proposal](https://discuss.px4.io/t/proposal-generic-airship-support-for-px4/48929), but I am keeping this topic intentionally limited to the airframe ID / `SYS_AUTOSTART` convention for airship configurations.

In [`ROMFS/px4fmu_common/init.d/airframes/CMakeLists.txt`](https://github.com/PX4/PX4-Autopilot/blob/c9b13827d996025511f19e6c67b752eb92a78299/ROMFS/px4fmu_common/init.d/airframes/CMakeLists.txt), IDs `2000–2999` are labeled `Standard planes`. However, the existing airship configuration [`2507_cloudship`](https://github.com/PX4/PX4-Autopilot/blob/c9b13827d996025511f19e6c67b752eb92a78299/ROMFS/px4fmu_common/init.d/airframes/2507_cloudship) also uses an ID in this range and is registered under `CONFIG_MODULES_AIRSHIP_ATT_CONTROL`.

Is this range intended specifically for conventional fixed-wing aircraft, or is the label only a historical grouping?

Should airships:

- remain in this range, with the label clarified; or
- have their own category and ID range?

I am also preparing a generic airship configuration. If airships remain in the current range, would `2500_generic_airship` be the appropriate filename and `SYS_AUTOSTART` ID? If a separate range is preferred, which base ID should the generic airship use?

I’d like to confirm both the range convention and the generic airship ID before suggesting a change, since `2507_cloudship` is already an established airframe configuration.

Thanks.

**Update:** I’ve opened [PX4-Autopilot #27697](https://github.com/PX4/PX4-Autopilot/pull/27697) adding a generic airship airframe, currently using **`2500`** — just below `2507_cloudship`, in the 2000–2999 band that’s documented as “Standard planes.”
