The DG Flugzeugbau DG-1000 is a two-seater class glider built by DG Flugzeugbau. It first flew in July 2000 at Speyer in Germany.{{Cite book |last=Barnard |first=Nick |title=How to Fly a Plane |publisher=Thames&Hudson |year=2007 |location=United Kingdom |page=51}} There are four models, with 18- and 20-metre wings of HQK-51 profile. The latest DG-1001 variant replaced the DG-505 in production.Bayerl, Robby; Martin Berkemeier; et al: World Directory of Leisure Aviation 2011–12, page 142. WDLA UK, Lancaster UK, 2011. ISSN 1368-485X
With a {{cvt|18|m|0|adj=on}} wingspan, it is fully certified for aerobatics (+7 -5 g); with a {{cvt|20|m|0|adj=on}} wingspan, it is certified for limited aerobatics (+5 -2.65 g).
The engine (DG1000T) is mounted on a pylon aft of the double cockpit. There is a reduction gear (2.3:1.0) between the engine and the two-blade carbon-fibre composite propeller. The propeller was designed by and made in the DG factory.
Operational history
In 2011, the DG-1000 was selected by the USAF as a replacement for the Blanik TG-10. It will serve as a basic soaring trainer for cadets at the United States Air Force Academy. It also serves as the primary competition platform for the USAF Academy Aerobatic Demonstration Team. Its USAF designation is TG-16A.{{cite web |url=http://www.koaa.com/news/af-academy-buys-19-new-gliders-for-cadet-training/ |title=AF Academy buys 19 new gliders for cadet training | koaa.com | Colorado Springs | Pueblo | |publisher=koaa.com |access-date=2012-12-06 |url-status=dead |archive-url=https://web.archive.org/web/20120324082626/http://www.koaa.com/news/af-academy-buys-19-new-gliders-for-cadet-training/ |archive-date=2012-03-24 }}{{cite web|author=Baillie, Amber |url=https://www.usafa.af.mil/news/story?id=123311630 |title=End of an era: 94th FTS phases out TG-10 gliders |publisher=Usafa.af.mil |date=2012-07-26 |access-date=2012-12-06 |url-status=live |archive-url=https://web.archive.org/web/20130104012837/http://www.usafa.af.mil/news/story.asp?id=123311630 |archive-date=2013-01-04 }}
