The authors in their study have performed the following simulations:

  • a control simulation for the air traffic of 2006 (simulation C2006-T06)
  • a simulation with increased air traffic according to the AEDT projection of air traffic for the year 2050 (simulation C2006-T50)
  • a simulation that additionally accounts for a changed background climate in 2050 (simulation C2050-T50)
  • a simulation that considers additionally an increase in fuel and propulsion efficiency as well as a change in emissions connected with the use of renewable alternative fuel, in particular a reduction in soot emissions by 50 % and a slight increase in the water emission coefficient connected with the use of alternative fuels (simulation C2050-T50M).
