Galaxy Aerospace has increased the gross weight of the Galaxy business jet to accommodate heavier than anticipated completion weights.
The 600lb (270kg) increase restores the Galaxy's range to 6,660km (3,600nm). Adjustments to the full-authority digital engine control schedule for the aircraft's Pratt &Whitney PW306A turbofans, coupled with drag reductions, increase cruise speed by 5kt to 575kt (1,060km/h).
The super mid-size Galaxy's design range goal was 6,700km, but heavier completions have resulted in lower payload and/or fuel weights within the original all-up limit. The changes, which will be retrofitted free of charge at scheduled inspection intervals, will provide more useful load and utility, the company says.
Like other business jet manufacturers, Fort Worth, Texas-based Galaxy has struggled to meet demand for completions, but believes it has overcome the challenge. Of the 19 aircraft in service, six were delivered in March. Completed aircraft will be handed over at the rate of three a month for the rest of the year.
Production of "green" Galaxys by Israel Aircraft Industries is running at two a month. The company is also producing and delivering the Astra SPX mid-size jet at a rate of one a month.
