With the growing focus on carbon, this brief comparison analysis from France below provides some perspective, when the inevitable conversation arises with a grumpy airfield spectator. It is not a justification for action or inaction on carbon abatement that I have read at length on these forums, but I note Friezpilots reference to the Friedrichshafen Aero 2024 exhibition and the emphasis on alternative propulsion technologies there.
Hence, I pose the question - what will general aviation (LSA type) look like in 25 years time and 50 years time ? It doesn’t really bother me, because I will be soil fertiliser by then, but it’s still interesting to speculate…..and let’s not get bogged down with too many flying car stories.
From another site…….
“Carbon emissions from light aviation activities can be estimated (FFA 2023 numbers) as follows:
The average consumption of our aircraft is around 25 litres/hour of aviation fuel (AvGAS), which represents 18Kg/hour of fuel consumed (this is average). In 2023 light aviation completed 492,000 flight hours, including 241,000 on double command (instructional). So those 492,000 hours consumed approximately 8860 tonnes. It turns out that one kilogram of AvGAS consumed emits 3.10 kg of CO2. The Aéro-Clubs of the FFA therefore emitted about 27,500 tonnes of CO2, figures we can compare to 12 million tonnes of French air transport, and 64 million tonnes of private cars. Emission from light aviation therefore account for 0.002% of French air transport, and 0.0004% of tourist cars. Our planes emit in a year what cars emit... In 4 hours.
Our aerodromes cover 460 km2, of which 337 km2 are green spaces rich in fauna and flora. A meadow capable of capturing 20 tonnes of carbon per hectare per year, let's do the math... and stop considering light aviation as a perfect scapegoat for many propaganda (see also the Citizen's Convention on Climate) and it's good to remember that aircraft is just a (small) part of society. Let's also imagine what would happen if we shut down our airfields. The spaces would be the prey of real estate speculation and would inevitably be concrete! “
