Gregory Polek has spent his entire career in aviation journalism with AIN, starting as a proofreader and assistant to then-managing editor Mary Mahoney in 1995 after serving an internship with&nbsp;New Jersey Monthly&nbsp;magazine and completing his B.A. degree in English/Writing at New Jersey’s William Paterson College. By 1997 Polek accepted a position as an associate editor, covering the regional airline beat for&nbsp;Aviation International News&nbsp;in place of retiring industry veteran Don Anderson. The assignment took Polek across North America and Europe to profile regional airlines varying in size and mission from the likes of floatplane operators Kenmore Air and Chalk’s Ocean Airways to regional jet operators such as SkyWest and American Eagle. Today, in his dual role as Air Transport Editor and International Airshow Editor, Polek writes, edits, and manages AIN’s commercial aviation content while overseeing each of the company’s daily international air show publications in Paris, Farnborough, Singapore, and Dubai. Most recently Polek has assumed oversight of daily coverage of the Helicopter Association International’s annual Heli-Expo convention.

As Embraer (Stand V01, Chalet CD31) awaits certification of the E190-E2 on static display here, Pratt &amp; Whitney remains hard at work addressing the last of the teething troubles associated with the PW1000G geared turbofan family at the heart of the performance gains the Brazilian airframer expects to realize. Briefing reporters on Sunday on show grounds, Embraer Commercial Aircraft vice president of marketing Rodrigo Silva e Souza reported that “a few” of the E2s slated for delivery this year will carry GTFs fitted with early-wear combustor liners known as configuration B, but that by the end of the year all E2s will carry engines with longer-wear configuration C combustors. He added that Pratt &amp; Whitney will retrofit the new combustors onto all the airplanes originally fitted with configuration B by year-end as well.

 


Out of between 85 and 95 E-Jets Embraer expects to deliver this year, some 10 percent will be E2s, said Silva. Plans call for first delivery to Norway’s Wideroe in April.

 


Final specifications for the airplane released late last month include 1.3 percent better fuel burn than original estimates, a more than 1,000-nautical-mile improvement in range from London City Airport and an additional 600 nautical miles out of Mexico City.

 


Aerodynamic improvements result in fuel-burn-rate decrease of 17.3 percent compared with that of the E190-E1, as opposed to the original estimate of 16 percent. The company attributes the improvement to better-than-expected performance of the new wing, an aerodynamically “clean” fuselage, and the “smart” use of the airplane’s fly-by-wire controls. More improvements come from flap slap and slat optimization during the flight test campaign and drag reduction on key elements such as landing gear.&nbsp;
