head to the tanks. This system ensures that the air space pressure in each
tank is the same, minimising uneven fuel feed rates.
The J160/J170 may use either two fuel sight gauges (one in each wing root) or
two electric fuel gauges on the instrument panel to show fluid levels in each
wing tank. The sump tank does not have a fuel gauge as its contents are
deemed to be unusable and should not to be considered for flight planning.
As an option, a low level warning light may be installed in the header tank.
NOTE
•
As ground & flight attitudes are essentially the same, fuel gauge
indications are valid in both cases
NOTE
•
Flying “1 ball” out of balance causes the fuel in the tanks to slosh in to
one side by an angle of about 8°. This leads to uneven fuel feeding – 1
tank emptying before the other. In extreme cases, this can cause fuel
starvation & engine stoppage while there is significant fuel remaining in
one wing tank. Care must be taken to fly the aircraft in balance at all
times.
CAUTION
•
In the unusual condition where the pilot suspects that one wing tank is
feeding and the other wing tank is not, the pilot must consider the fuel
in the non-feeding tank as “unusable” and manage the flight
accordingly.
BRAKE SYSTEM
The aircraft has a single disc, hydraulically actuated brake on each main
undercarriage wheel.
Each brake is connected by a hydraulic line to a master cylinder fitted to the
front of the centre console in the cabin. The wheel brakes operate
simultaneously.
