The four trips will be awarded using the following method looking at challenges from each Stage of the TCO17:
1. Remove copilots who have fulfillment less than 85% in their development challenges. (Design challenges are not considered in the fulfillment calculation. If a copilot has only design challenges then this filter will not be applied.)
2. Rank the remaining copilots by earnings made. The top earner from each Stage will win the trip!
