Summary

It is shown that the trailing vortex wakes generated by large aeroplanes can cause serious upsets (loss of control) to smaller following aircraft that may encounter them and may damage buildings near an airport. The increase in separation behind big aircraft imposed as a safety measure leads to a serious loss of runway capacity.

After discussion of the nature of wake vortices, it is demonstrated that they may be attenuated, so avoiding unnecessary separation between aircraft at an airport and, at the same time, obviating ground damage.

Discussion of alternative devices available for moderating the vortex wake indicates that practical solutions may be confidently expected.
