Q

Is the impact of aviation on climate change big?

A

No, it only accounts for around 1,5-3% of global carbon emissions. But until 2030 it could be up to 1/4 of uk’s contribution to global warming

Q

How does the CO2 pricing work?

A

Airlines receive a specific amount of tons of CO2 emissions they can use. The rest they don’t use they can sell -> incentive to use less / buy more efficient airplanes

Q

What is the big picture of sustainability of air transport?

A

Global with respect to climate change

Regional with respect to noise, smell and politics

17
Q

What are the three perspectives concerning sustainability of air transport?

A

Local around airports, national and international

18
Q

Why are larger airplanes interesting in terms of technical development?

A

Efficiency of an airplane increases with increasing size

19
Q

What is one reason for minimum time space between starting planes?

A

Wake turbulence

20
Q

What are design considerations for wide bodies?

A

Lower ratio of surface compared to volume
Faster boarding, loading, deboarding
Wider fuselage: better ground maneuverability, greater fright capacity

21
Q

What are typologies of the “new generation aircraft”?

A

Composite materials: carbon fiber, reinforced plastics, light and strong, no metal fatigue, lighter and stronger aircrafts, less maintenance, carrying more PAX

Efficiency and economics: 20% more efficient, better engines, new wing design

22
Q

What are implications of new Wide Bodies in terms of Success factors network/Hub Airlines?

A

Extensive market coverage, alliance and ability to adapt good and homogenous processes

23
Q

What are implications of LARGE wide bodies?

A

long range, economies of scale and scope, mega hubbing

24
Q

What are implications by new small wide bodies?

A

Longer range, connecting hubs, more passengers, convenince, less fuel

25
Q

What are problems with ageing aircrafts?

A
  • 20 years old aircraft cause 50% higher maintenance cost
  • spare parts supply = problematic
  • increased maintenance = less availability
  • higher fuel costs
26
Q

How do airplanes look like in the future?

A

Single wing with slight delta shape, integrationof passenger cabins and cargo room in the wing, up to 1500 passengers transport capacity, new fuel (thermo-electric power), no passenger windows anymore for the benefit of weight decrease

27
Q

Success factors of manufacturer

A
  • technology –> constant development

- product platforms –> capital needs

28
Q

Social System: positive and negative?

A

positive: connectivity, social intercultural interaction and time savings
negative: noise and health
