Lane failure/fault indication modes
NOTE
:
please refer to Rotax 912 iS series Operators Manual for additional
and detailed information.
The Rotax 912 iS Series uses a dual redundant system of fuel pumps, fuel
injector, ignition system, ECUs and generators. The control and ingnition
system is divided in two independent and complementary systems named
LANE A and LANE B. Normal operation is with both lanes ON (Auto mode).
Engine can operate also with a lane malfunction.
Failure modes of LANEs are indicated with 2 (two)
LANE warning lights
on
the main electrical panel. The lights indicate three modes:
LED OFF
Proper healthy operation, no malfunction.
LED intermittent
(blinking)
Abnormal operation, LANE fault. Pilot is advised to
manually switch to the remaining healthy LANE. It
is recommended to land soon and inspect engine
systems to discover fault.
LED ON (permanent)
LANE failure, pilot MUST manually switch over to
healthy LANE and land as soon as practical.
Fuel Pumps
The system uses two redundant high pressure fuel pumps. Should a pump
fail, the other pump can replace its role. Only one functional pump is re-
quired for the engine to function nominally. In case of a pump failure, switch
over to the remaining healthy pump. Should the engine quite before the
pump is activated, restart engine normally. Should both fuel pumps fail, the
engine cannot be restarted as not enough fuel pressure is produced.
