Regarding the CBA carried out, the following computations have been required in connection with the aforementioned parameters. It has to be noted that an example of the Lleida - Alguaire Airport is provided forwards (year 2010 of the analysis), taking into account that the same calculation method has been applied in relation to the other analysed years and airports.

In fact, all the computations and Cost Benefit Analyses are provided in the Annex 3 and 4.

- Other Cash Flows:

In relation to the item “Other Cash Flows”, it is necessary to consider an investment of (-90.000.000 €) at the first year, a residual value of (+36.000.000 €) at the last year and a

constant maintenance cost of (-78.700 €) each year.

- Road Travel Time Cost:

Regarding that it has been assumed that 70% of the passengers that land in the mentioned airports have Andorra (Pyrenees) as their final destination, recreation has been considered as the reason of their trip. Therefore, a cost of 7’31 €/(hour·person) has been applied.

It has also to be noted that there are 159 km between Lleida and Andorra (2’2 hours) and that a bus capacity of 55 passengers is considered. Furthermore, in connection with the parameter

“time”, it has to be considered the double of one trip time due to the fact that passengers have to go from the airport to Andorra and, at the end of their holidays, they have to go back to the initial airport so as to fly home.

For instance, the road travel time cost for the Lleida - Alguaire Airport and at the year 2010 has been carried out as follows:

7^′31 €

ℎ𝑜𝑢𝑟 · 𝑝𝑒𝑟𝑠𝑜𝑛· (2 · 2^′2 ℎ𝑜𝑢𝑟) · (70

100· 61769 𝑝𝑒𝑟𝑠𝑜𝑛) = 1.390.716^′68€

- Air Travel Time Cost:

So as to compute the air travel time, it has been assumed that an Airbus A-321 is used, that its average speed is 800 km/h and its capacity is 180 passengers. The air distance between the considered that a functioning cost of 0’85€/(vehicle·km) has been assumed due to the fact that buses are used. These buses have a capacity of 55 passengers and the trip distance is 159 km from the airport of Lleida to Andorra. The following calculation has been realized:

0^′85 €

𝑣𝑒ℎ𝑖𝑐𝑙𝑒 · 𝑘𝑚· (2 · 159𝑘𝑚) · 1 𝑣𝑒ℎ𝑖𝑐𝑙𝑒 55 𝑝𝑒𝑟𝑠𝑜𝑛· (70

100· 61769𝑝𝑒𝑟𝑠𝑜𝑛) = 212496′59€

- Bus Pollution Cost:

So as to compute the bus pollution cost, it is necessary to consider the aforementioned heavy vehicles pollution cost of 43’8€/(1.000km) and, in addition to this, that the bus capacity is 55 passengers and that the bus has to travel 159 km so as to go from the airport of Lleida - Alguaire to Andorra. Therefore, the following calculation has been realized:

43′8€ Andorra are separated by 159 km and that the capacity of the used buses is 55 passengers per bus. Hence, the bus noise cost is computed as follows:

10′2€ 154’28€/(1.000vehicles·km). Moreover, it has to be considered that the airports of Lleida and Gatwick are separated by 1400 km and that the capacity of the used aircrafts (A-321) is 180 passengers per aircraft. Hence, the passenger’s aircraft noise cost is computed as follows:

154′28€

1000𝑣𝑒𝑐ℎ𝑖𝑙𝑒𝑠 · 𝑘𝑚· (2 · 1400𝑘𝑚) · 1 𝑣𝑒ℎ𝑖𝑐𝑙𝑒

180 𝑝𝑒𝑟𝑠𝑜𝑛· (61769𝑝𝑒𝑟𝑠𝑜𝑛) = 103.768′08€

- Bus Driver Cost:

Regarding the bus driver cost, the aforementioned cost of 16’91€/(hour·vehicle) is assumed in relation to the used buses of 55 passengers capacity. Moreover, the road travel time from the airport of Lleida - Alguaire to Andorra is 2’2 hours. Hence, the following computation has been realized:

16′91€

ℎ𝑜𝑢𝑟 · 𝑣𝑒ℎ𝑖𝑐𝑙𝑒· (2 · 2′2ℎ𝑜𝑢𝑟) · 1 𝑣𝑒ℎ𝑖𝑐𝑙𝑒 55 𝑝𝑒𝑟𝑠𝑜𝑛· (70

100· 61769𝑝𝑒𝑟𝑠𝑜𝑛) = 58.492′77€

- Bus Fuel Cost:

In relation to the bus fuel cost, it has been assumed that the average bus consume (55 passenger capacity) is 0’3L/km and its cost 1’1029€/L. Moreover, the distance of the road trip is 159 km. The following calculation has been done:

1^′1029€

𝐿· 30𝐿

100𝑘𝑚· (2 · 159𝑘𝑚) · 1 𝑣𝑒ℎ𝑖𝑐𝑙𝑒 55 𝑝𝑒𝑟𝑠𝑜𝑛· (70

100· 61769𝑝𝑒𝑟𝑠𝑜𝑛) = 82.716′17€

- Number of Bus Accidents and Bus Accidents Cost:

Therefore, regarding the parameters indicated before, the 159 km between the airport of Lleida - Alguaire and Andorra and that buses of 55 passengers capacity are used, the following calculation has been realized:

Therefore, in order to compute the pilot cost, it has been assumed that the cost of the first pilot is 41’01€/(hourflown) whereas the cost of the second pilot is 13’89€/(hourflown).

Consequently, the total pilot cost is 54’9€/(hourflown). Taking into account that the flight duration from Gatwick Airport to Lleida - Alguaire Airport is 1’75 hours and that Airbus A-321 with 180 passengers capacity is used, the following calculation has been realized:

54^′9 €

ℎ𝑜𝑢𝑟 𝑓𝑙𝑜𝑤𝑛· 2 · 1^′75ℎ𝑜𝑢𝑟 · 1 𝑣𝑒ℎ𝑖𝑐𝑙𝑒

180𝑝𝑎𝑠𝑠𝑒𝑛𝑔𝑒𝑟𝑠· 61769𝑝𝑎𝑠𝑠𝑒𝑛𝑔𝑒𝑟 = 65.938^′41€

-Aircraft Fuel Cost:

In order to compute the aircraft fuel cost, it has to be considered that the average aircraft A-321 fuel consume is 5L/km and that the average fuel (kerosene) price is 0’38€/L. Moreover, regarding that the airports of Gatwick and Lleida - Alguaire are separated by 1.400 km and that the capacity of an Airbus A-321 is 180 passengers, the following computations has been done:

aforementioned values of CO2. Therefore, the following computation has been realized (note that, as aforementioned, the value of CO2 changes depending on the analysed year):

28€

Regarding that passengers aircraft noise cost is 154’28€/(1000vehicles·km), that Airbus A-321 with capacity of 180 passengers and that the flight distance from the airports of Gatwick and Lleida - Alguaire is 1.400km, the following calculation has been realized:

154^′28 €

1000𝑣𝑒ℎ𝑖𝑐𝑙𝑒𝑠 · 𝑘𝑚· (2 · 1400𝑘𝑚) · 1 𝑣𝑒ℎ𝑖𝑐𝑙𝑒

180𝑝𝑎𝑠𝑠𝑒𝑛𝑔𝑒𝑟𝑠· 61769𝑝𝑎𝑠𝑠𝑒𝑛𝑔𝑒𝑟 = 148.240′11€

-Aircraft Functioning Cost:

So as to compute the aircraft functioning cost and in relation to the flight Gatwick - Lleida Airports, the aircraft functioning cost that has been considered is 8’14€/passenger. Therefore, the following calculation has been realized:

8^′14 €

𝑝𝑎𝑠𝑠𝑒𝑛𝑔𝑒𝑟· 61769𝑝𝑎𝑠𝑠𝑒𝑛𝑔𝑒𝑟 · 2 = 1.005.599^′32€

Eventually, it has to be noted that, regarding air travel, passengers have to go from Gatwick Airport to the analysed airport and, at the end of their trip, they have to do the same journey again so as to get home. This situation also happens regarding the road transport from each analysed airport towards Andorra, as passengers have to return to the analysed airport so as to be able to fly back home. Owing to this fact and in connection with the aforementioned calculations, some of the parameters are multiplied by 2 (the trip distance or the trip time).
