A soon-to-be-released very light jet forecast from PMI Media estimates that 7,650 VLJs, worth some $18.36 billion, will be delivered between 2007 and 2016. “We are predicting 2007 deliveries of VLJs to be around the 200 mark, up from our 2006 forecast of 175. In the first half of 2007, 31 Cessna Mustangs and Eclipse 500s were delivered, so the second half of the year should see a steep ramp up in production activity,” the forecaster wrote. While the VLJ order book currently stands at more than 4,010 aircraft, the research firm said there are still “major uncertainties” in this emerging market. In particular, PMI cites questions about the suitability of the new aircraft types to the robust demands of the air-taxi market and the consequence of continuing production delays at Eclipse. Another worrisome indication, the forecaster said, “is some anecdotal evidence that the current volatility in global economic markets might soon impact the VLJ and wider business jet sectors.”
