Unison Industries announced today that it has received FAA-PMA status for its LASAR® (Limited Authority Spark Advance Regulator) Digital Engine Control System for Lycoming O-540 and IO-540 series engines with 25° base ignition timing. This new approval makes the LASAR system available for most aircraft that use Lycoming engines. To purchase LASAR, visit Unison's Web site (www.unisonindustries.com) for a list of authorized Unison distributors, or e-mail Unison at buyLASAR@unisonindustries.com.

Examples of certified aircraft outfitted with Lycoming 540 engines and perfectly suited for the latest generation LASAR system include the SIAI Marchetti, the Piper Cherokee, and the Piper Comanche. Homebuilt and experimental aircraft such as the Glasair and the Harmon Rocket are also ideal LASAR candidates.

Installation of the LASAR system takes approximately four hours. LASAR can be installed in the field or during an engine overhaul by an A&P or a qualified engine shop. Kitbuilders and experimental aircraft owners who choose to install LASAR themselves can use Unison's detailed Service/Installation Instructions and special magneto timing equipment.

LASAR was first made available for installation on most Lycoming -320 series engines and associated airframes in 1996. Certification of the LASAR system for installation on Lycoming -360 series engines followed in 1997. In 2000, Unison's LASAR system received FAA-PMA status for installation on Lycoming IO-540 series engines with 20° base ignition timing.

LASAR is the first and only FAA-PMA Approved microprocessor-based electronic engine control system for GA piston engine aircraft. LASAR improves engine starting, rate of climb, and engine idle performance. LASAR also reduces fuel consumption in cruise conditions by up to 12 percent. Unlike traditional full authority digital engine controls (FADECs), LASAR provides redundant magneto-based ignition as a backup in the event of an aircraft electrical power interruption.

LASAR users clearly benefit from increased fuel efficiency and improved engine performance. Hans Georg Schmid relied on LASAR in his Long-EZ that completed a record-setting 24,154 nautical mile flight around the world. "LASAR enabled me to reduce my total fuel consumption and complete several 15-hour flight legs without refueling," said Schmid. "I wouldn't leave home without the LASAR system."
