Leaky Cabin At 45,000' - How Long Can You Last?

Want to fly high and fast? See how well you know high-altitude physiology and oxygen rules with this quiz...

  1. 1) While cruising at 20,000 feet, you lose pressurization. How long do you have before you're no longer effective?

    Awesome

    You lose effectiveness after around 30 minutes, and fall unconscious shortly after.

  2. 2) One ounce of alcohol makes your body feel like it's:

    Awesome!

    One ounce of alcohol can make your body feel like it's 2,000 feet higher.

  3. 3) While cruising at 25,000 feet, your cabin altitude starts dropping.  How long until you're no longer effective?

    Awesome!

    You've got about five minutes until you're no longer effective at 25,000 feet.

  4. 4) You're cruising at 23,000 feet, ferrying a King Air with a broken pressurization system.  What oxygen system are you wearing?

    Awesome!

    You should wear a rebreather bag above 18,000. It's good up to 25,000'.

  5. 5) You've got an oxygen tank with cannulas in your 182 and you're taking a night flight. When does the AIM say you should start using oxygen?

    Awesome!

    The AIM recommends you wear oxygen at night above 5,000 feet.
