Selecting his link above launches the IAC Contest Calendar. IAC provides online contest registration using a button adjacent to each Regional Contest entry in the contest calendar.
After completing online registration for a Chapter 67-sponsored contests, pilots can choose the option of paying the registration fee with a PayPal button by returning to this page.
As of mid-January, 2020, the Chapter 67 contests for the coming season haven't been posted to the IAC calendar.
We want to make absolutely certain that the PayPal option is completely secure and protected from mischief before offering this option; registering and paying the fee can also be accomplished at the contest.
