In this episode of the VSL Aviation Podcast, Seth takes a deep dive into high altitude operations, breaking down FAA requirements, oxygen systems, and cabin pressurization from both a technical and checkride prep perspective. Whether you're a Commercial, CFI, or ATP applicant, you'll gain practical insight on:

• The types of oxygen systems you’ll encounter in GA aircraft
• How to calculate oxygen requirements for your flight
• FAA Part 91.211 rules and what “if installed” really means on a checkride
• Physiological risks of flying without oxygen above 10,000 feet
• Best practices for maintaining and using onboard oxygen systems
• Real-world stories, Q&A, and prep tips for earning your high altitude endorsement

Plus, Seth outlines how to use AC 61-107B as a ready-made lesson plan and shares additional resources including the FAA’s O2 brochure, SkyOx system specs, and pressurization system maintenance best practices.
