Oxygen basics for pilots

Medical and aviator oxygen is 99.5% pure, and industrial, or welders oxygen, is 99.2% pure. The biggest difference between medical and aviator oxygen is the moisture content. Medical oxygen can contain 67 ppm of moisture. Industrial oxygen can contain 50 ppm of moisture. Aviation oxygen can contain 7 ppm of moisture.

Flight planning for a weekend getaway

There is nothing like trying to depart on a Sunday morning and needing assistance when no one is around. The departure date or day of the week can make a difference. Check the FBO operating hours and emergency (after hours) phone number. I always plan for enough fuel to fly to another airport for fuel if something happens and I am not able to fuel up at the destination airport.
