So, I know the regulation says that the pilot needs to have oxygen if flying above 12,500 ft PA for more than 30 minutes. I never fly that high, but was wondering if you fly at 13000 ft for 25 minutes and then descend to 12500 or lower: how long to you have to wait before flying back up to 13000 again? (I'm not talking about what is physiological or what is smart. I'm asking whether there is a regulation or an FAA guidance letter.)

Thanks

Do you think the FAA could be persuaded to relax the stadium TFR during games with no fans?
