NBAA is expecting to draw 2,000 attendees to its Business Aviation Regional Forum on Thursday at Teterboro Airport in New Jersey. Landmark Aviation is hosting the event, which will feature 174 exhibitors and 34 aircraft on static display. Based at the busiest business aviation airport in the nation, the Teterboro event tends to be among the largest of NBAA’s regional forums.   The association estimates that TEB generates $2.3 billion in economic activity, including $868 million in wages. The forum will provide a venue to cover both local and national issues. NBAA president CEO Ed Bolen is scheduled to discuss policy issues. Industry experts also will provide overviews of market and financing trends, the nois- abatement program and business aircraft appraisals and evaluations.
