Welcome to the HALO homepage. These web pages are currently undergoing a major overhaul. We will be restructuring existing information and add more information on current and planned projects and missions with HALO. For the time being (April 2015) you might find a few broken links or empty pages. This will be corrected as soon as possible.

Welcome to the HALO homepage

The High Altitude and LOng Range (HALO) Research Aircraft is the new research aircraft for atmospheric research and earth observation of the German science community. HALO was funded by the Federal Ministry of Education and Research, the Helmholtz-Gemeinschaft and the Max-Planck-Gesellschaft. HALO is based on a production G550 business jet from Gulfstream Aerospace Cooperation. The aircraft is operated by the Flight Experiments facility of DLR (Deutsches Zentrum für Luft- und Raumfahrt; German Aerospace Center) in Oberpfaffenhofen, near Munich.

Latest HALO news


The POLSTRACC/GW-LCYCLE/SALSA mission is about to start soon. Preparations are underway. Instrument integration into HALO will start next week. Today the GLORIA instrument arrived at DLR in Oberpfaffenhofen.


In the past 9 weeks a series of certifcation flight tests for the GLORIA instrument, for the new KIT dropsondes and for the POLSTRACC exterior aircraft configuration have been successfully performed with HALO.

GLORIA is a complex remote sensing instrument developed and operated by KIT and FZJ which is mounted in the HALO belly pod. The flights for the GLORIA instrument aimed at finding a belly pod configuration which mimimizes vibration and acoustic effects for the benefit of the instrument's scientific performance. Furthermore the flight tests were needed to demonstrate the absence of significant electro-magnetic interference effects as well as any adverse aerodynamic or aeroelastic effects, a prerequisite for the final airworthiness certifcation of the GLORIA belly pod configuration. GLORIA was also fully tested with respect to its scientific operation. Altogether 10 flights were performed with full success regarding all of the objectives.

The POLSTRACC exterior aircraft configuration consists of the combination of the GLORIA belly pod configuration with six trace gas inlets (TGIs) on the upper fuselage of the aircraft. Two certifcation flights covering handling qualities and performance qualification were also successfully performed. This is a prerequisite for the POLSTRACC/GW-LYCLE/SALSA scientific mission with HALO starting in December 2015.

Upcoming activities
