Terlet Airfield is a small airfield in the Netherlands 2.5 NM north of Arnhem in Gelderland and close to Deelen Air Base. It is used mainly by gliders and motor gliders, as well as some light aircraft such as the Aviat Husky, mainly used as tugs for the gliders. It has six grass winchtracks, 04L/22R, 04C/22C, 04R/22L, 12/30, 14R/32L and 14L/32R. From only one strip motorised aircraft are allowed to operate, and only when prior permission is obtained.
The field was founded in 1952 by the Koninklijke Nederlandse Vereniging voor Luchtvaart to promote glider flying, though glider flying has taken place from the area since 1932. It is now home to the largest glider flying association in the Netherlands.
