The HA­LO project was made pos­si­ble by the Max Planck So­ci­ety, mem­bers of the Helmholtz As­so­ci­a­tion of Ger­man Re­search Cen­tres and var­i­ous oth­er sci­en­tif­ic in­sti­tutes in the at­mo­spher­ic re­search sec­tor. In to­tal, 31 re­search in­sti­tutes are in­volved in the project.

Modifications for HALO: From business jet to research aircraft

HA­LO (High Al­ti­tude and Long Range Re­search Air­craft), the new re­search air­craft of the Ger­man Aerospace Cen­ter (Deutsches Zen­trum für Luft- und Raum­fahrt; DLR), is com­plete.In a 20-month project, RU­AG Aerospace Ser­vices have con­vert­ed the brand-new Gulf­stream G550 from a stan­dard busi­ness jet in­to the state-of-the-art and high­ly spe­cialised high-al­ti­tude re­search air­craft for DLR's at­mo­spher­ic re­search ac­tiv­i­ties.The graph­ic shows the mod­i­fi­ca­tions on the up­per and low­er fuse­lage.

The new HALO (High Altitude and Long Range Research Aircraft) research aircraft heralds a new chapter in the history of German atmospheric research and Earth observation. HALO is based on a Gulfstream G 550 ultra-long range business jet. The combination of range, cruising altitude, payload and comprehensive instrumentation make the aircraft a globally unique research platform.
