Avionics Electrical Technician First Class (AET1) SWE Practice Test

The situation tested is how mission readiness is blocked by the type of constraint. When a critical part or supply item is not available, the asset cannot be flown or deployed, so it is Not Mission Capable Supply. This specifically flags that the limitation is due to missing parts in the supply chain, not due to maintenance work or a repair action. Not Mission Capable Maintenance would apply if maintenance manpower or resources were the bottleneck, while Not Mission Capable Repair indicates a repair action is needed or in progress rather than a missing part. Fully Mission Capable means there are no such blockers.
