Understand the connected system

Trace stored oxygen through the shutoff/regulator to crew, first-aid and passenger branches. Understand SYSTEM READY, automatic and manual passenger deployment, the container-door relationship, local lanyard outlet and pressure-switch reports. Learn why stored pressure or a dropped mask alone does not prove individual flow.

Practise defensible fault isolation

Complete six prediction-and-Apply exercises, eight two-stage cases, separate crew/passenger/high-pressure leak comparisons and twelve independent decisions. Complete all 24 lab requirements and pass a separate 40-question final at 80%. Based on supplied Beechcraft 130-590031-11 Chapter 35 with November 2025 effective pages; current aircraft and supplier tasks govern physical work.
