Backup Mode Operation
When operating in the backup mode the LASAR
®
system provides traditional magneto ignition. The
LASAR
®
system automatically switches to the backup mode when the system receives inadequate
electrical power, or internal system diagnostics detects a hardware or software fault. The system may
be manually switched to backup operation by turning the ignition switch to the “LEFT” or “RIGHT”
position, or by interrupting input power to the controller by manually pulling the circuit breaker, if
equipped. Engine performance in the backup mode is identical to engine performance with traditional
magnetos. During backup mode operation the LASAR
®
controller provides a ground return path for the
cockpit enunciator light (if equipped) which becomes illuminated provided the light is receiving
adequate input power. To restart the engine in-flight with the LASAR
®
ignition system operating in the
backup mode, windmill the engine above 500 rpm.
Piloting
Operation of the LASAR
®
system is transparent to the pilot under most conditions. Unless the aircraft
is equipped with a cockpit enunciator light, the pilot is typically unaware of the two million logic and
control command decisions that take place inside the controller every second. What the pilot does
experience with LASAR
®
Ignition is better engine starting and smoother engine operation resulting from
the controller’s decisions and commands.
The performance improvements including reduced fuel consumption realized on any aircraft will be
dependent on the flight profile, throttle and mixture settings, engine RPM, CHT, manifold pressure, and
the cylinder to cylinder balance of the induction system. For flight planning purposes, always follow the
original operating manual including mixture leaning procedures and cowl flat operation.
CAUTION:
NEVER FACTOR IN ANY IMPROVEMENT IN FUEL CONSUMPTION RESULTING
FROM LASAR
®
ENGINE CONTROL SYSTEMS, AS THESE IMPROVEMENTS WILL
VARY FROM FLIGHT TO FLIGHT DEPENDING ON THE FLIGHT PROFILE AND
MIXTURE LEANING PROCEDURE.
1.4
FUEL OCTANE REQUIREMENTS
The LASAR
®
system is approved for use on engines operating with a minimum fuel grade of 100
octane. Operation of LASAR
®
equipped engines using a minimum fuel grade of less than 100 octane
has not been validated.
