Class: CasSystem

Defined in: src/sdk/cas/CasSystem.ts:189

A system for CAS management.

Every avionics system must have exactly one instance of CasSystem configured as the primary system. This is the one that is responsible for triggering sim-level master caution/warning alerts and intercepting and handling master acknowledge events.

Each JS instrument should have at most one instance of CasSystem. Multiple instances of CasSystem on a single instrument will cause duplicated events to be published to the topics defined by CasStateEvents.
