LARS 1 VLJ Being Prepared For First Flight Polish company Flaris is currently working on a VLJ (Very Light Jet) they announced at the Paris Air Show last year. It is a single-engine jet in the VLJ segment that Flaris is trying to bring to market. Williams International has been chosen to provide the single powerplant in the form of a Williams FJ33-5 turbofan. The engine has already been installed on the first aircraft. Testing on the engine is anticipated to commence this month ahead of the first flight slated for Spring.
