The Schreder HP-16 is an American mid-wing, single seat, V tailed, FAI Standard Class glider that was designed by Richard Schreder.
After the failure of the HP-15 to perform well in the 1969 US Nationals Schreder started the HP-16 with a new design philosophy. Avoiding the extremely high aspect ratio that the 15 had, he opted for a more modest 21.5:1 aspect ratio and larger wing area to improve performance in weak conditions. The HP-16's wing has 50% more wing area than the HP-15 and uses a Wortmann 67-150 airfoil.
Like other Schreder designs the HP-16 is of all-metal construction, but with the wing skins bonded to foam ribs rather than using rivets to provide a smoother surface. The bonded construction also cut building time. The wing features the signature Schreder 90ð flaps that allow steep descents and the use of small fields for landing.
The HP-16s were all amateur-built aircraft and about 20 were completed and flown.
In April 2011 there were still eleven HP-16s registered with the US Federal Aviation Administration and two registered with Transport Canada.
