  4. 4. Aircraft industry – Current and Projection Data EU: 2008: Top 10 airports with 25 Mio passengers each per year Mio. Global: 2008: ca. 1.5 billion passengers per year 20.000 aircraft 2029: 36.900 aircraft 2050: ca. 5.0 billion passengers per year Future: - CO2 certificates and Carbon Trading - Increasing oil price - More competition - Hi h pressure on margins High i - Environmental protection - Increased utilization of existing facilities©2010 | Freitag, 10. September – 12. Symposion IAI | Page 4
  5. 5. Gate positions „Space challenge“ GSE IATA: $4.0 – $5.0 Billion US for damages on ground per year, 82% of these are when the aircraft is on the aircraft centre line line. USE THE FREE SPACE©2010 | Freitag, 10. September – 12. Symposion IAI | Page 5
  6. 6. GSE challengesExisting above ground solutions Requires increased space and with a risk of collisions!
  7. 7. GSE challengesEnvironmental challenge High emissions from JET A1(CO2, NOx, SO2 etc) from Aircraft and Mobile Equipment
  8. 8. GSE challengesGround support challenge Increase of GSE traffic Increase in F l C t I i Fuel Costs Increased manpower (therefore reduced security) Fixed amount of Space Increase of co-ordination Reduce turn around time Reduce risk of aircraft damages Increase gate productivity Clear link between GSE / Environment / APU
  9. 9. What does APU mean? APU A380 APU stands for “Auxiliary Power Unit” and is an additional engine on the back of the aircraft. The main purpose of an aircraft APU is to provide power to start the main engines after the push back of the parking position. The APU is also used as a backup in flight in case of an engine failure The primary auxiliary failure. function of the APU is the power supply as well as cooling and heating in the parking position.©2010 | Freitag, 10. September – 12. Symposion IAI | Page 9
  10. 10. How is the APU used? Starting of the main engine Power supply in parking position Air conditioning, cooling and heating in p g, g g parking p g position Auxiliary engine Currently the usage of the APU is far more then the originally intended auxiliary function for starting the main engine.©2010 | Freitag, 10. September – 12. Symposion IAI | Page 10
  11. 11. What does APU-Free mean? An APU-Free airport only allows the usage of the APU to start the main engine and requests the APU to be switched off as soon as the parking position is reached.©2010 | Freitag, 10. September – 12. Symposion IAI | Page 11
  12. 12. What does APU-Free mean in detail? An APU-Free airport limits the operation of the APU on the starting of the main engines. All necessary power supply, air conditioning as well as cooling and heating during the ground servicing is provided by the airport operator. Starting of main engine APU on Power supply in parking position APU off Air conditioning, cooling/heating in parking position APU off©2010 | Freitag, 10. September – 12. Symposion IAI | Page 12
  13. 13. What does APU-Free airport mean? emissions CO2 costs ecology politics finance economy noise traffic Airports need to balance environmental aspects, economic viability, p p , y, politics and regulations under given limited financial resources. The goal is to reduce the CO2- and noise emissions while at the same time traffic increases and costs need to be under control.©2010 | Freitag, 10. September – 12. Symposion IAI | Page 13
  14. 14. What does APU-Free Airport mean in detail? The current usage of the APU - starting the main engines but also during the th parking position - contribute 8% of airports’ carbon f t i t ki iti t ib t f i t ’ b footprint. CO2-emissions during the ground servicing cycle can be measured per hour as given in the following table: Aircraft type Jet A1 fuel CO2-emissions Noise-emissions Small size aircraft 150 kg 0,5 t >80 db Wide body aircraft 250 kg 0,8 t >80 db A380 450 k kg 1,4 14t >85 db 85©2010 | Freitag, 10.

  15. 15. Jet fuel cost $100 per barrel = $788 per metric ton March 2010 => $ per kg jet fuel $1
  16. 16. What is the potential of an APU-Free airport? The potential of an APU-Free airport illustrates this example: Assumptions for a medium-size airport: - 30 active gates (park position in use) - usage of gates 14 hours per day - 365 days per year On average APU uses 250kg Jet A1 fuel and distributes 0 8t CO2 per 0,8t hour.Emissions per day y Emissions per year y Costs of CO2 certificates($30(USD)/t) ( ( ) ) 336t CO2 122,640t CO2 $3.7Mil Fuel costs: 250kg x $1 =$250/h x 30 gates x 14h/day x 365 days = $38 Mil./ Year ©2010 | Freitag, 10.

Alternatives in detailsAirport operators provide solutions for the ground servicing of aircraft.The power supply and air conditioning as well as cooling and heating during the p pp y g g g gground servicing is provided by the airport operator.Environmentally friendly solutions lead to the reduction of fuel consumption of allground service units as well as minimizing the traffic on ground with the positive sideeffect of fewer collision incidents, reduced insurance cost, less aircraft down time. parking positions Prohibition of APU usage Power supply and air conditioning ground servicing as well as cooling and heating by airport operator©2010 | Freitag, 10.
