1. Make cabin lighting and even flight deck electrics run on dynamo generated electricity (similar to wind up radios/torches) This will save on engine generators thus reducing fuel burn. (note: all dynamos must be charged preflight to prevent carrying excess weight.) The F/O could calculate number of turns required preflight as part of his duties.
2. Shellsuits/paper forensic suits as uniforms. They could have painted ties and stipes on them, but think of the weight you would save!
3. Drill holes in the skin and fill them with cork. Add an extra hole per sector. After the first hull loss, reduce number of holes drilled by one
4. Put those flush saver devices for toilets in the fuel tanks. You would carry less weight in fuel, but the gauges would still show minimum reserves on landing.
5. Fill tyres with helium.
6. Only operate from airports where the apron is higher than the runway. The upslope could be used instead of braking. And you could free wheel to the threshold before starting engines.
I love this thread, keep it up guys.............
