Which wing type is likely to need greater speeds for takeoff and landing?

The delta wing design is characterized by its triangular shape and broader wingspan, which leads to a unique aerodynamic profile. This design allows for high-speed flight and improved performance at higher altitudes, often resulting in a higher stall speed compared to more traditional wing types like straight wings. As a consequence, aircraft with delta wings require greater speeds for takeoff and landing.

The advantages of the delta wing include better lift at high speeds and superior maneuverability, particularly in supersonic flight. However, the trade-off is that to generate sufficient lift at lower speeds, as required during takeoff and landing phases, the aircraft needs to achieve these greater speeds. This attribute makes the delta wing especially suitable for military jets and certain experimental aircraft rather than commercial airliners, which need to operate effectively at lower speeds.

In contrast, straight wings predominantly used in conventional aircraft designs tend to produce adequate lift at lower speeds suitable for takeoff and landing requirements. Truss wings and monocoque wings serve specific structural purposes but do not inherently influence speed requirements for takeoff and landing in the same manner as delta wings.
