Abstract: An aircraft approach path indicator (1) including a projector unit (6) adapted to provide three discernibly different signals (11, 12, 13), wherein one of the signals (11) indicates an approach path which is too high, one of the signals (12) indicates an approach path which is too low and the other signal (13) indicates an approach path which is safe, and wherein the three discernibly different signals comprise bands of light, wherein the three different signals are generated by a first projector (6a) and a second projector (6b), wherein the first and second projectors are located in fixed relationship to each other, and wherein each projector emits light of a different colour in a band, and wherein the two bands of light emitted by the projectors overlap, and wherein in the region of the 10 overlap a third band of light of the third colour is formed.

Abstract: A weapon system comprising a firearm having a barrel through which a projectile may be propelled and further comprising a non-lethal means for selectively ejecting a stream of fluid, such as an incapacitant, in a direction substantially parallel to the axis of the barrel and aligned with the sights of the firearm. The system removably houses a fluid containing pressurized canister, the outlet of the canister co-operating with a nozzle for the release of said fluid from said canister under control of a nozzle trigger mechanism. The pressurized canister, nozzle and trigger mechanism may be removably mounted on said firearm.
