While the landing gear is retracted both valves are energized and excessive hydraulic fluid on one side is drained into the tank. This configuration of the system is shown in the following figure.


For an emergency extension of the landing gear, the hydraulic fluid can pass through an emergency extension valve so that the gear is extended by gravity. The condition of the system is shown in the figure below.

 

 

7.6 SEATS AND SAFETY HARNESSES
To increase passive safety, the seats are constructed using a carbon fiber/Kevlar hybrid material and GFRP. The seats are removable to allow maintenance and inspection of the underlying controls. Covers on the control sticks prevent loose objects from falling into the area of the controls.
The seats have removable furnishings and are equipped with energy-absorbing foam elements.
The seats are fitted with three-part safety harnesses. The harnesses are fastened by inserting the end of the belts in the belt lock, and are opened by pressing the red release on the belt lock.
The backs of the rear seats can be laid forward after pulling upwards on the locking bolt knob.
' If front seats with adjustable backrests are installed (O.M 42-067), the angle of the ' backrests can be adjusted for best comfort. The backrest lever is situated on the outboard ' side of the backrest. However, during take-off, landing and emergency landing the ' backrests must be fixed in the upright position designated by a placard on the roll-over ' bar.
' CAUTION ' Before the backrest lever is lifted in order to unlock the ' backrest, lean back towards the backrest to counteract the ' spring load; otherwise the backrest may snap forward.
' ' For adjustment lift the backrest lever and bend forward or backward to the desired backrest ' angle. Then lift the backrest lever fully, release and press down to set the friction lock.

' If possible, set the backrest lever to the ”locked” position. The mechanism must be repaired ' at the next scheduled inspection.
' The lumbar support can be adjusted by operating the lumbar support lever mounted on ' the outboard side of the seat pan.

7.7 BAGGAGE COMPARTMENT

The other baggage compartment is behind the seat backs of the rear seats. Baggage may be loaded there provided it is restrained by means of a baggage net.
