Fixed wing aircraft have many advantages over other types of vehicles:

1. Fast. At present, the cruising speed is about 900 km / h.
2. High mobility. Fixed wing aircraft flight from the mountains, rivers, deserts, oceans, and can be increased according to the number of passengers, the number of goods at any time.
3. Safety and comfort. According to the International Civil Aviation Organization statistics, the number of deaths of civil aviation passenger kilometers per billion to 0.04 people, is one of dozens of road traffic accident death toll to hundreds of, and rail transport as the safest mode of transportation.

But fixed wing aircraft as a means of transport has its own limitations:

1. Expensive. Whether it is fixed wing aircraft or fixed wing aircraft used by the oil consumption is relatively high compared to other modes of transport.
2. Affected by weather conditions. Although aviation technology has been able to adapt to the vast majority of meteorological conditions, but the more severe wind, rain, snow, fog and other weather conditions will still affect the safety of aircraft landing.
3. Landing site restrictions. Most of the fixed wing aircraft need Airport lift, the need for a longer runway for take-off and landing, the requirements for landing conditions are more stringent.
4. Certain danger. Although the number of deaths per passenger kilometer is far lower than other common means of transport, but the survival rate of the accident is very low, so the public’s psychological feeling is still a certain risk.

In addition, although the fixed wing aircraft continue to improve fuel efficiency, but every 1 kg of fuel consumption will be 3 kg of carbon dioxide emissions when flying in the atmosphere and gas emissions, the effects of global warming is larger than the surface discharge.
