What Aranmula needs is environment conservation’

Uptake of water by contrails in ice-supersaturated air and release of water after ice particle advection and sedimentation dehydrates the atmosphere at flight levels and redistributes humidity mainly to lower levels. The dehydration is investigated by coupling a plume-scale contrail model with a global aerosol–climate model. The contrail model simulates all the individual contrails forming from global air traffic for meteorological conditions as defined by the climate model. The computed contrail-cirrus properties compare reasonably with theoretical concepts and observations.

The airline industry closely monitors the midlatitude jet stream for short-term planning of flight paths and arrival times. In addition to passenger safety and on-time metrics, this is due to the acute sensitivity of airline profits to fuel cost. US carriers spent US$47 billion on jet fuel in 2011, compared with a total industry operating revenue of US$192 billion.

Sometime this summer, a United Airlines flight will fly from Los Angeles to San Francisco using fuel generated from farm waste and oils derived from animal fats.

Solar Impulse 2, which is attempting to fly between Japan and Hawaii powered only by the sun's energy, has broken a world record for the longest non-stop solo flight.
