To limit the increase in operating costs, and the necessary quantities of SAFs, aircraft efficiency will have to increase by about 50 per cent. This could be the path 👇 #BauhausLuftfahrt #SparksOfKnowledge #FutureOfAviation
German Aerospace Center (DLR) Jolanda Stevens Reduced cruise speed is not an option. Cruise speed impacts revenue miles flown per day, at a one-to-one ratio. Faster, more revenue per day. Slower, less revenue per day. Flying slower only reduces energy costs, which are a fraction of total operating costs = approx 30%. Flying slower is an economic disaster for airlines.

Nice to see different possible impacts to increased aircraft (AC) efficiency including percentage assessment of each technology step! Please keep in mind, that these technology steps are not the path to hydrogen in AC - they also increase efficiency of kerosene powered AC! Hydrogen costing disadvantes need to be fixed by 1. CO2 emission costs 2. hydrogen #technology scaling 3. hydrogen technology innovation. Your view to this? ...we work on challenge #3...🙂
Clean Aviation = Clean Propulsion
3moClean Aviation There is no practical way - repeat, no practical way - aerodynamic efficiency and propulsive efficiency of airplanes like the 787-9 and A350-1000 can be improved by a combined total 50%. Increased aviation energy costs shall be entirely absorbed by commercial aviation customers. With rigorously zero taxpayer money involved in the process of refueling commercial aircraft. Period.
