from an aerospace engineer:
"...If aircraft had variable camber systems (The A350 already has this), this should be literally free, the reason it increases fuel burn is because changing altitude can throw you off your design lift coefficient (CL), but variable camber effectively redesigns the wing in real time to re-optimise the wing for the new CL point. The potential performance recovery is insane. ..."

from a comment:
"...warming effect comes only from PERSISTENT contrails. In certain conditions, over certain parts of the planet, contrails will form, and stick around, gradually spreading out and forming high altitude cirrus clouds. it is THESE which cause that warming effect. [...]We (military air forces) have been monitoring where such regions of the atmosphere are [...]so that fast jets are harder to pick out,"
