Cessna continued its aggressive program of incremental product improvements with the first flight of the newly announced Citation Encore+ in late March. In terms of avionics, the Encore+, which Cessna expects to be certified for single-pilot operation, incorporates many of the improvements rolled into the "Plus" lineup of CitationJets, with electronic charting, graphical weather and enhanced mapping. Providing the motive force for the Encore+ is a pair of 3,400-lb thrust Pratt & Whitney PW535B engines with dual-channel fadec. The jet will boast a 200-pound maximum weight increase, giving it a 1,100-pound full fuel payload (in addition to two pilots). Certification is scheduled to take place by the end of the year. New: Garmin GMX 200 Garmin has introduced the successor to the popular MX20 multifunction display, the GMX 200. While Garmin says that the new product is "similar to the MX20," it's really an all-new product that does everything the MX20 does and much more, while fitting into the same panel space as the MX20. For starters, the GMX 200's display is big, 20 percent larger than the MX20, and the screen resolution, 640 x 480, is even better than the excellent MX20's screen res. There's also a new rotary knob, a much requested improvement, to allow for faster data entry and range changes. Also new on the GMX 200 is an industry-standard Secure Digital (SD) card slot on the front of the unit, so uploading data-most new PCs have an SD slot built in - is easier, and buying additional cards is cheaper, too.
