I am looking for a discussion of how your club handles this problem. Background: Our waiver is 15K. We have a number of what I will refer to as altitude junkies. They continually ask to kiss the waiver sometimes regardless of wind and weather. I have always gone by the 10% rule. If you are going 13,500 feet or higher, you can't fly it on our field. We have considered making a rule that 8K or higher needs a simulation file or calculation to back up how high you will fly and preapproval. How does your club handle these flights?
