Abstract: A steering angle warning system comprising a rotation-measuring unit located on an aircraft, and an alarm unit. The rotation-measuring unit is arranged to output a first signal dependent on the steering angle between a nose landing gear of the aircraft and the longitudinal axis of the aircraft fuselage. The alarm unit is arranged to generate an alarm, in dependence on the first signal, when the steering angle is greater than a predetermined value, for example, 60 degrees. The rotation-measuring unit may also be arranged to perform a function in relation to an aircraft steering system, for example to indicate the steering angle to the pilot during ground manoeuvres.

Abstract: This invention relates to methods of fastening seating to the floor of vehicles, and in particular to systems for allowing the seating to slide for adjustment or removal. Accordingly, a seating system is provided in which the longitudinal configuration and spacing of the seats may be more easily altered, without compromising safety. There is provided a seat anchorage system for seating carried in a vehicle including a track adapted to be attached to the load area of a vehicle, a traveller member configured to inter-engage with the track for longitudinal movement therealong and fixable to a seat, and securing means operative to permit securing of a seat associated with said traveller member in a desired position so as to prevent longitudinal movement of the seat.
