3.2 Pressurization & Environmental

DRAFT lesson page — content pending POH verification and video production.

Learning Objectives

• Describe the pressurization schedule and the air source / outflow path
• State max cabin differential and cabin altitude at FL310 ‹VERIFY POH›
• Respond correctly to a pressurization failure at altitude

In This Lesson

• Air source (engine bleed) → cabin → outflow valve, which sets cabin altitude
• The cabin stays low while the aircraft climbs to FL310
• Environmental / temperature controls and oxygen
• Max differential and cabin-altitude schedule ‹VERIFY POH›
• A pressurization failure at altitude is time-critical: oxygen, then emergency descent (Module 7)

Video

In production — original pressurization schematic and cabin-schedule animation + Austin controls footage + AI voiceover.

Knowledge Check

• The outflow valve sets cabin altitude
• Maximum cabin differential ‹VERIFY POH›
• A pressurization failure at altitude calls for oxygen, then an emergency descent
• Cabin altitude at FL310 ‹VERIFY POH›
• The pressurization air source is engine bleed air
