Aerospool Advantic WT10 high altitude test for GLWF 2020

Advantic WT10 Research was build for black carbon research. In April we are planing to start GLWF 2020 in India, Bhutan, Nepal Himalaya. So we need actual numbers what our aircraft is capable. 120 l of fuel, 80 kg on pilot seat and maybe 10 other things put CG forward what means a bit less cruise speed and poorer climb. Nevertheless OM-ADC behave a lot better that I expected. Very stable at high and low speed, good climb, have still some 300-500 ft/min at altitude 7000 m. At FL160 and 28 MP (17-18 l/h consumption), 4800 RPM, crusing 140+ kts TAS, at FL120 still 133+ kts. After some 10 hours I can say for me the most pleasant plane I have flown till now.
