Ultralight Aircraft with a Ballistic Rescue System

Four manufacturers dominate in Europe. Junkers Magnum (formerly Magnum by Stratos 07) is especially widespread in Germany and is offered in several size classes up to 600 kg. BRS from the USA is the oldest supplier on the market and is regarded as the origin of the technology. Galaxy GRS from the Czech Republic is frequently fitted at the factory on aircraft from Eastern European manufacturers. USH (Ultralight Safety Holding) is mainly found on older German types. Technically the systems differ in deployment speed, minimum deployment altitude and weight — functionally they all solve the same problem.

Two intervals run independently of each other. Depending on the manufacturer, the parachute has to be repacked every five to six years — it is inspected, dried and repacked in the process. The solid-fuel rocket has its own, longer service life of roughly twelve to fifteen years and is then replaced rather than overhauled. Both dates are recorded in the system's paperwork and can be requested from the seller. An expired system does not make an aircraft unsellable, but depending on what is due it shifts a four-figure amount onto the buyer — a legitimate point for negotiation.

Older ULs without a rescue system can in many cases be retrofitted, provided the manufacturer has approved a suitable installation. On top of the cost of the system come installation, weighing and an amendment to the data sheet — and useful load drops by the weight of the system, which is noticeable in the 472.5 kg class. Retrofitting usually only makes economic sense for aircraft you intend to keep for a while. If you are buying anyway, an already installed and freshly packed system is almost always cheaper than the retrofit route.
