SUMMARY
The discussion highlights several demerits of winglets in aviation, particularly focusing on their impact on aircraft performance and costs. Key drawbacks include the fixed costs associated with purchasing winglets as an aftermarket feature, the expenses incurred from taking aircraft out of service for installation, and the need for additional routine inspections. Furthermore, winglets increase the overall weight of the aircraft due to the additional structure required for support and alter the aeroelastic behavior of the wings. While WestJet reported a 10% fuel savings relative to installation costs, the benefits may vary based on fleet utilization and operational routes.
