Logbook Skill Lifecycle State Machine

This state machine diagram illustrates the various states a logbook skill entry can transition through during its lifecycle.

Currency Status State Machine​

Instructor Approval Authority State Machine​

Skill Request Lifecycle State Machine​

Key State Transitions​

Critical Business Rules​

  1. Currency Dependency: Many state transitions depend on active currency status
  2. Progression Gates: Certain states can only be reached after completing prerequisites
  3. Suspension Memory: System remembers pre-suspension state for proper restoration
  4. Timeout Protections: Automatic state changes prevent requests from lingering
  5. Retry Mechanisms: Failed attempts don't permanently block progression

State Persistence​

  • All state changes are logged with timestamp and actor
  • Previous states stored for suspension/reactivation cycles
  • State history maintained for audit trail
  • Bulk state changes tracked separately

This state machine design ensures consistent skill progression management while handling edge cases like currency expiration, administrative actions, and complex approval hierarchies.
