Delta wings are most commonly seen on military aircraft. I understand that delta wings are ideal for supersonic flight, and provide high maneuverability.
Having high maneuverability and speed are good characteristics for commercial airliners. But, most of the commercial airliners do not use delta wings (Except for Concorde and Tu-144).
- Are there any specific reasons for this?
- Are there any regulations that prevent using delta wings in commercial airliners?
- Does it cost more in maintenance?
