Fuel; flight control; hydraulic pneumatic systems

a. Hydraulic, mechanical, electro-optical, or electro-mechanical flight control systems (including fly-by-wire types);

It also includes any storage reservoirs for the operating medium and the return lines, but not the vehicle's engine (except for the purposes of item 4.1.3) or its drive to the energy source; 1.3.4.1. Energy source means that part of the energy supply which provides the energy in the required form e.g. hydraulic pump, air compressor; 1.3.4.2. Energy reservoir means that part of the energy supply in which the energy provided by the energy source is stored; 1.3.4.3. Storage reservoir means that part of the energy supply in which the operating medium is stored at or near to the atmospheric pressure. 1.4. Steering parameters 1.4.1. Steerin ...[+++]g control effort means the force applied to the steering control in order to steer the vehicle; 1.4.2. Steering time means the period of time from the beginning of the movement of the steering control to the moment at which the steered wheels have reached a specific steering angle; 1.4.3. Steering angle means the angle between the projection of a longitudinal axis of the vehicle and the line of intersection of the wheelplane (being the central plane of the tyre, normal to the spin axis of the wheel) and the road surface; 1.4.4. Steering forces mean all the forces operating in the steering transmission; 1.4.5 Mean steering ratio means the ratio of the angular displacement of the steering control to the mean of the swept steering angle of the steered wheels for a full lock-to-lock turn; 1.4.6. Turning circle means the circle within which are located the projections onto the ground plane of all the points of the vehicle, excluding the external mirrors and the front direction indicators, when the vehicle is driven in a circle; 1.4.7. Nominal radius of steering control means in the case of a steering wheel the shortest dimension from its centre of rotation to the outer edge of the rim. In the case of any other form of control, it means the distance between its centre of rotation and the point at which the steering effort is applied. ...

For steering equipment in which the steering forces are provided solely or partly by the muscular effort of the driver the steering control includes all parts up to the point where the steering effort is transformed by mechanical, hydraulic or electrical means; 1.3.2. Steering transmission includes all parts of the steering equipment which are the means of transmitting the steering forces between the steering control and the steered wheels; it includes all parts down from the point where the steering control effort is transformed by mechanical, hydraulic or electr ...[+++]ical means; 1.3.3. Steered wheels means the wheels the alignment of which may be altered directly or indirectly in relation to the longitudinal axis the vehicle in order to determine the direction of movement of the vehicle (The steered wheels include the axis around which they are rotated in order to determine the direction of movement of the vehicle); 1.3.4. Energy supply includes those parts of the steering equipment which provide it with energy, control the energy and where appropriate, process and store it.

2.2.1.12.2.the failure of a part of a hydraulic transmission system shall be signalled to the driver by a device comprising a red tell-tale lamp lighting up not later than on actuation of the control and remaining lit as long as the failure persists and the ignition (start) switch is in the on (run) position.

The review found that some wiring systems were difficult to inspect and that there were insufficient inspection criteria for corrosion on flight control and hydraulic systems.
