2020:
Electricity is mostly used fo A/C system utilities
Bio fuel is used in operation and in conjonction with fossil fuel for the propulsion
Commercialy & socially viable non drop-in alternative fuel are identified
The proposed vehicle concepts allow propulsion energy change in the Second part of the century
2035:
The lower band of the vehicle size (general aviation, bizjets, rotorcraft, regional A/C) can be electrically powered
Vehicle compatible with hybrid propulsion with high density energy storage capability.
Vehicle compatible with non drop-in kerosen type fuel
2050:
The higher band of the comertial vehoicle can be electrically powered
the storage and distribution technologies of alternative energy is capable to support electrical propulsion and systems at competitive cost and conditions
Vehicle compatible with non kerosene type fuel
