Why do cargo aircrafts make use of supercritical airfoil?

A)
Better takeoff and landing performance
B)
No vortex formation
C)
Thinner airfoil resulting in less wing weight
D)
More fuel carrying capacity in thicker airfoil

Correct Answer :   Better takeoff and landing performance


Explanation : Supercritical airfoils work efficiently even in the transonic regime. It’s unique geometry of large leading edge, flatter top surface and cusp shape at the bottom aft section all result in high lift. This leads to very good take-off and landing performance as during this flight regime, higher lift is required. For this reason, cargo flights make use of supercritical wings.
