Some types of variable geometry vary the wing sweep during flight:

The first successful wing sweep in flight was carried out by the Bell X-5 in the early 1950s.

The outputs controlled the primary flight controls, wing sweep, the F-14's leading edge "glove", and the flaps.

The level of wing sweep, the angle of the wings in relation to the fuselage, can be altered in flight at the pilot's control.

These other elements (such as wing sweep, vertical mount point of the wing, etc.) may be more difficult to change than the dihedral angle.

The design was controversial, and the Short SB5 was built to test wing sweep and tailplane combinations.

The wing sweep varied between 16 degrees and 72.5 degrees (full forward to full sweep).

The low wing sweep will give a good low-speed performance and excellent handling characteristics essential for the trainer role.

As wing sweep is conventionally measured at the 25% chord line an unswept wing may have a swept or tapered leading edge.

The aircraft will have a T-tail empennage, area-rule fuselage contouring, and 30 wing sweep.
