Im just a simple single pilot 135 VFR. I was asked the other day if a passanger could use his medical oxygen poor health I suppose. I told them that he couldn't. I checked my ops specs and there is nothing that says anything about passanger using there own provided oxygen. Only that we must provide oxy to passangers above such and such altitude, than that we don't have a way to provide oxygen and than we can't fly over a certain altitude. We don't carry hazmat either and the boss hasn't sent me to hazmat recongization trainging. So I guess to sum it up can I take this old fart or not?
