I've always flown in a club whose hourly charges are wet rates. I was wondering how does one pay for clubs that use dry rates for aircraft. So paying the hourly dry rate is simple, but how do they manage the cost of fuel. If I fill up the tanks with my own credit card, but then only use up half of the fuel, does the next pilot reimburse me for what he's used and so on? or do the clubs or flight schools come out to check who's used how much fuel. I was just wondering how the dry rate charging method works.
