7.4.1.7 External Audio Jack
The external audio jack accommodates a 2.5 mm stereo plug and
connects an audio source to the auxiliary input of the intercom unit.
Sound level must be controlled at the source.
7.4.1.8 Electric Fuel Pump
The 912S engine has a mechanical fuel pump and is backed up by an
electrical pump for priming and emergency operation. The 914 engine
has no mechanical pump but has two electric pumps. The power for one
primary pump comes through the main power source and the second
backup pump is connected through its own circuit breaker directly to the
battery. All electric pumps have check valves in parallel with them.
Fault? The aircraft may be operated without the use of its primary
mechanical or electric pump. It is not recommended that a flight be
initiated with an inoperable electric fuel pump.
7.4.1.9 Bilge Pump
Before takeoff, the interior of the hull step area should be checked for
water accumulation. The bilge pump should be used to expel the water.
Do not run the pump continuously but only until no more water is being
pumped out.
Fault? The aircraft may be flown with a failed bilge pump so long as
there is no appreciable water accumulation in the hull. Water operations
should be avoided.
7.4.1.10 Emergency Locator Transmitter (ELT)
The ELT is mounted in the nose area. It has a control panel on the
instrument panel for testing the transmitter and observing its operation.
The pilot should become familiar with its operation and maintenance by
consulting the user manual.
7.4.1.11 Alarms
The EFIS on Elite Aircraft provides alarms for the following parameters
when they go outside their normal range. In addition to audio warnings, a
red LED acts as a master alert indication:
Oil pressure
Oil temperature
Head temperature (CHT R & L)
Engine speed (RPM)
