Categories & Types
A two-level classification of the fleet — categories contain types — that rules target by stable ids so renames never break them.
What it is
Categories & Types give the fleet a two-level classification. A category — such as glider, tow-plane or microlight — groups together the specific models, or types, that belong to it. Every aircraft sits under exactly one type, and every type under one category.
This structure is what lets pricing and qualification rules target aircraft broadly (“any glider”) or narrowly (“this specific model”) without listing planes one by one. Crucially, rules reference categories and types by their stable internal ids, not their names, so you can rename a category or type for clarity at any time and never silently break the rules that depend on it.

How to use it
- Browse categories — the list shows each category in the fleet; open one at
/aircraft-categories/[id]. - Manage types — add or edit the specific models within a category at
/aircraft-categories/[id]/types. - Rename freely — relabel a category or type whenever you need; rules follow the stable id, not the name.
- Target rules — use categories and types as conditions when writing pricing or qualification rules.
