Releases for aerotow
types E-72, E-75 and E-85 are all normally interchangeable
The E 85 tow release is used as nose release for gliders and power gliders or as tail release for tugs. The maximum cable load is 14.1 kN, the manual release force 140 N. The E 85 has no automatic release. Approved by LBA type certification 60.230/1 as conforming to airworthiness regulations for tow releases, this release also meets JAR 22 requirements. Since 2001 the body of the E 85 tow release is recessed on the side so that an external release lever can be fitted.

Center-of-gravity releases for winch launching
types G72, G73 and G88 are all normally interchangeable
The Europa G 88 safety release is approved for gliders and power gliders for cable loads up to 14.1 kN. Automatic release occurs with the cable at an angle of 83 ?7°. The maximum manual release force is 140 N. The tow release meets JAR 22 requirements and has been approved, and documented in type certification 60.230/2, by the German aviation authority (Luftfahrt-Bundesamt) as conforming to their stringent airworthiness regulations for tow releases. Approved for a maximum all-up weight of 850 kg.

G 88 with release lever      028000
Standard version with 4-position release lever.
Mass: 700 g.

G 88 without release lever    028200
Allows a release lever to be fitted by the aircraft manufacturer, or the release cable can be attached directly to one of the segment holes. Mass: 670 g.


G 88/1-83      028400

Special-purpose releases
The S 72 and SH 72 special tow releases are for light-weight gliders and power gliders with a simpler design (without movable ring mechanism). To satisfy airworthiness requirements, therefore, the aircraft must have cable deflectors to ensure release even for extreme lateral cable angles. Approved by LBA type certification 60.230/3 for a maximum aircraft all-up weight of 500 kg. Refer to the LBA before using this release for new aircraft designs.


S72    022100
Without release lever, for attaching the release cable directly to one of the segment holes. Mass: 600 g.



SH 72    022210/022200
For space reasons, the segment is shortened by three holes and the segment bolt is extended for fitting a special release lever (cf. G 88/1-83). On DG aircraft the release lever is mounted on the left, in flight direction (022200), and on Glas-
flügel aircraft on the right (022100). Mass: 565 g.

Piccolo    022300
The safety release specially designed for winch launching of light gliders up to an all-up weight of 200 kg. The features are the same as for S 72. Automatic release is at 83° cable angle, the manual release force is 110 N. Mass: 260 g.

TOST Connecting ring pair


A ring pair is required between the release hook and the tow cable. lt must meet the specifications of the current edition of the LN 65091 standard and must be stamped with the manufacturer's name and the standard number.

Maintenance intervals for all Tost releases: A release must have a type certification. Its safety and operating life can be guaranteed only by keeping to the prescribed maintenance intervals. After 2000 starts or 10000 release operations, it must be returned to the manufacturer for complete reconditioning and check to the regulation of the LBA. We recommend a general overhaul after 4 years, because in our experience tow releases, even if carefully looked after, will corrode or become stiff because of environmental factors or poor accessibility
