Definitions
The reusable vocabulary of the club: membership types, certificates, flight tasks, duty types, transaction types and custom fields.
Small lists of reference data that the rest of the app draws on.
Memberships
The membership-type vocabulary every member is assigned to — the basis for pricing tiers and recurring fees.
Certificates & Licenses
Definitions of pilot licenses and ratings, with the validity intervals that feed proficiency tracking and qualification checks.
Flight Tasks
The catalogue of flight activity types — dual, solo, tow, cross-country — used to classify flights and drive pricing.
Duty Types
The classifications of club duties and shifts — line management, retriever crew, instructor — used to roster and bill duties.
Transaction Types
The categories used to classify ledger entries — flight charge, membership fee, refund, penalty — so payments and statistics group meaningfully.
Custom Fields
Club-defined fields added to members, aircraft and flights without any schema change, letting each club capture data the base model doesn't cover.
