Test flights from 1 July to 1 December 2026 of an experimental stratospheric airship in the Durham-Thargomindah-Charleville vicinity, with potential drift up to 300 km.
We are planning a series of test flights of an experimental stratospheric airship, designed to operate above 60,000 feet. Test flights will be conducted in the Durham-Thargomindah-Charleville vicinity in the South West corner of Queensland. Please see the image below for the operational area.
Each test flight will last less than 24 hours from take-off to landing. The airship will make a buoyant ascent like a balloon at approximately 1,000 feet per minute (fpm), drifting with the wind. Once above 60,000 feet, the experimental propulsion and control system will be tested and manoeuvres will be attempted. At the completion of testing, the airship will commence a parachute-style descent back to the ground.
The airship is registered VH-DJU as a Large Remotely Piloted Aircraft in the Airship category. When fully inflated, it is 30 metres long and 10 metres in diameter. Its fabric is shiny metallic, making it highly visible in daylight. For night operations, it is fitted with anti-collision strobe lights.
The airship is fitted with a fully certified (TSO’d) Mode S / ADS-B transponder. Flights will be conducted under IFR flight plans, and with ATC clearances while in Class E and Class A airspace. While in Class G airspace at the beginning and end of each flight, we will make periodic VHF radio calls from our ground control station on relevant CTAF/Multicom and area frequencies.
We will be operating in conjunction with the operator of a temporary restricted area (TRA) in the area and will be operating both within the TRA and outside of the TRA.
A Notice to Airmen (NOTAM) will be issued for the commencement of each flight.
We welcome any feedback or discussions. We are happy to add any aviation organisations to our notification list to receive brief update messages during our flight operations.
