Welcome to the HALO homepage

The "High Altitude and Long Range Research Aircraft" (HALO) is the new research aircraft for atmospheric research and earth observation of the German science community. HALO is based on a production G550 business jet from Gulfstream Aerospace Cooperation. It has been modified in many ways to offer the technical infrastructure for very diversified scientific payload requirements. The aircraft is operated by the Flight Experiments (FX) facility of DLR (Deutsches Zentrum für Luft- und Raumfahrt; German Aerospace Center) in Oberpfaffenhofen, near Munich. The Special Airport of Oberpfaffenhofen (ICAO code: EDMO) is HALO's homebase. HALO was initially funded by the Federal Ministry of Education and Research, the Helmholtz-Gemeinschaft and the Max-Planck-Gesellschaft. The operational standby costs are shared by six German research centers and the DFG (Deutsche Forschungsgemeinschaft), which represents the German universities, together forming the HALO consortium. The HALO consortium partners are the main scientific users of the aircraft, but it is in principle also open to other users.



These pages aim to provide further information about HALO and the science projects making use of HALO. Please find right below announcements of   UPCOMING ACTIVTIES   as well as   LATEST NEWS   items a bit further below. To navigate to all other contentent please use the menu on the left.

The HALO homepage was offline for a couple of months and is (again) undergoing a major overhaul, which will take some time. For the time being you might still find a few broken links or empty pages. Please be patient, but do not hesitate to contact us if you are missing particular content or if you find anything wrong.

KITsonde flight testing ongoing

Certification flight tests for the new KITsonde dropsonde system for HALO are currently underway. The challenge is to demonstrate that there is a clean separation of the dropsondes from the aircraft after release as well on low (10000 ft) as on high (40000 ft) altitudes and at different aircraft speeds. The KITsonde system is a a new multi-sensor dropsonde system of modular design for high and fast-flying research aircraft such as HALO developed by KIT. For further information follow this link. The photograph was taken during one of the pre-flight briefings. The KITsonde system, once certified, is planned to be part of the scientific payload of the SOUTHTRAC mission following later in the second half of the year.

This is the first news item on the HALO homepage since more than a year. Due to low staff capacity and some open questions regarding the new General Data Protection Regulation (GDPR) introduced in May 2018 the homepage was essentially offline for a long while. Data privacy is important and you find the statement on data privacy policy in the footer at the bottom of each page or in the left hand main menu. There are quite a few pages here on the HALO homepage which requires updates. These will be done the course of the next weeks.
