Pre-takeoff checklist
It’s been suggested to me that age, health and other factors influence your altitude tolerance. Okay, I agree - so I picked up a small pulse oximeter I can use in the cockpit to check my oxygen levels during long flights at higher altitudes.
My question is how to interpret the values. If I read 98 or 99 on the ground, when is it time to put on the mask? 90? 60? 30?
