How does aviation impact the environment What could be done to improve things - Essay Example Many aircrafts use avgas (Aviation Gasoline) as a fuel. It contains tetra-ethyl lead (TEL) that is a highly toxic chemical. It causes soil pollution at airports. It also pollutes air and causes various respiratory problems. The greatest threat caused to the environment is in the form of the chemical gases that emit out of the aviation aircrafts. So, these should be considered specifically. First of all, improvement in the design of aircrafts engine is required. An engine which reduces the emission of toxic gases such as Carbon dioxide, Carbon monoxide and nitrogen oxides is required. This may greatly reduce the environmental pollution caused due to these gases. Despite manufacturing new engines, the improvement in older engines can also be helpful. High-pressure turbine nozzles, upgraded gas turbines and steam injection can greatly assist in minimizing the pollution. Another requirement is to design engine which reduces the fuel combustion as fuel burn also contributes heavily to the air pollution. Moreover, light aircrafts can be run on lower-compression engines which may be operated on mogas (Motor Gasoline) mogas does not contain tetra-ethyl lead (TEL). thus, using mogas instead of avgas will be hel pful in minimizing air pollution. Another way of reducing environmental pollution caused from aviation is by improving operational efficiency of the aircraft i.e. by increasing the number of passengers in each flight. This will reduce the emissions per passenger. The reduction in taxi time may also be helpful in reducing pollution. Pollution may also be reduced by reducing energy output during landing, takeoff and taxi
