Portela limitations and the need for a single new Airport for Lisbon


ADP Studies and Today presentationADP undertook in 1998-19999 a synthesis of the previous studies of new

airport sites (Ota and Rio Frio), complemented by :

- Update of traffic forecast

- New air operations organisation studies

- Evaluation of capacity of Portela airport, including a Super Portela concept

- Preparation of a typical new airport layout

Today presentation, based on materials from this consultancy comprises :

- Portela and Super Portela capacity

- Update of traffic forecast

- New airport strategy

- Rio Frio and Ota sites

- Evaluation and recommendation

- Future of Portela after opening of Ota new airport


Portela Airport PotentialRunways- Runway 17/35 (2 400m x 45m) offers very little capacity, but brings operationalflexibility and emergency solutions (VMC only)- Capacity of runway 03/21 (3 800m x 45m) could be increased up to 35-38 mvts / h within airport boundariesTerminal- Check-in capacity ~ 3 200 p/h- Baggage claim capacity ~ 2 800 p/h- Boarding capacity could be increased withnew north pier (8 more gates = 15 contact gates)Apron- 15 contact gates + 12 hard stands- Capacity : up to 25 hard stands between runways

Ultimate capacity- 38 mvts / hour- 15 + 25 = 40 apron stands (+ 5 reserve + cargo)- 2 800 pax / hour- 13 Mp / year- 150 000 T cargo


The Super Portela Option

T2

Capacity bottlenecks of Portela :- Apron capacity, constrained by runway 17/35- Runway capacity- Terminal capacity (gates, curbside, bags)

Super Portela concept :- 80 ha land acquisition, with expropriation of 10 000 people (!)- Closure of runway 17/35- New close parallel runway 03/21, 365 m sepa-tion (code E)- New taxiway to runway 21, 122 m separation- New terminal T2, south of existing hard stands- Estimated cost in the range of 800 M€

Super Portela capacity :- 55/60 mvts/h- 70 traffic apron stands- 20 Mp- 240 000 T cargo


Updated Traffic Forecast (1998)2020 traffic forecast

4.4% average growth

- 2000 : 8.8 Mp- 2005 : 11.2 Mp (10.6 in 2004)- 2010 : 13.8 Mp- 2015 : 16.8 Mp- 2020 : 20 Mp

Long term potential- 28 MP in 1998- 35 Mp today, on account of the outbreak of LCC.

Portela capacity (13 to 20 Mp) is not sufficient for the long term.


The new Airport Strategy

A new airport site is a must for Lisbon, as even Super Portela would not be sufficient beyond 2020.

When to move to the new airport ?- Building a new airport may be a lengthy process, about 8 to 10 years

- Traffic forecasts show that Portela may reach capacity soon : 13 Mp in

2009, 17 Mp in 2015 !- The more the transfer is delayed, the more capital expenses to be exposed

for temporary extension of Portela- Due to capacity shortfall, level of service at Portela may seriously fall in

the last years before transfer- Transfer should then occur as soon as possible


New Airport typical layout

Long term capacity requirements

- 30-35 M passengers- 300 000 mvts / year- 75 mvts / hour- 100 traffic apron stands- 400 000 T cargo

- 2 parallel independent runways, with ~ 1700 m separation- All facilities in between the runways- Code F capability

- Airport city at the airport entrance

- Minimum site overall size : 5 500 m x 2 500 m, or 1 400 ha


Location of candidate sitesRio Frio

42 km east of Lisbon and 15 km of Setubal, on the left bank of rio Tejo, near Pinhal Novo

- Runway orientation 17/35, non compatiblewith Alcochete shooting range

- Alternate orientation 08/26, compatiblewith Alcochete and Montijo Air base

Ota

45 km north of Lisbon, near Alenquer.

- Former air base with 17/35 runway

- New 01/19 runway orientation necessary to ensure convenient obstacles clearance

Consultant Recommendation

The multi-criteria analysis clearly showed the following.

- Rio Frio (08/26 runway orientation) is the best site for aeronautical purposes, road access and construction costs- Rio Frio (17/35 runway orientation) is the best site for noise impact- Ota is the best site for rail access, natural environment impact and operational costs

On account of the Government decision to disqualify Rio Frio sites for risk of “serious, irreversible and non mitigatible natural environment impact”, Ota is an acceptable site for the new Lisbon airport.


Evaluation of Portela Options- Munich (1992), Oslo (1998) and Athens (2001) all decided, with comparable level of

traffic, to transfer in full and one shot to the new airport, the old one being closed to air

traffic.

-Should Portela retain some commercial traffic, this would bias competition between

airlines staying at Portela and others moving to the new airport (see Milan issue with

Linate and Malpensa).

- The only acceptable split would be between short and long haul flights.

- Such split would be a disaster for TAP Air Portugal, then unable to built a competitive

hub between continental and intercontinental services

- Compatibility of significant air traffic at both Ota and Portela does not seem practicable

from ATC viewpoint

- Cost of running 2 airports instead of one would be significantly higher

- Continuation of air operations in Portela would also mean continuation of noise impact

over approximately 200 000 people which could be spared with the full transfer. - Redevelopment of Portela and surroundings will be easier with full closure to air traffic


Conclusion

Like in Munich, Oslo and Athens, we recommend the full closure of Portela to air traffic at opening of Ota new airport.

Assuming an implementation time between 8 to 10 years for Ota new airport, the traffic expected at the opening will be over 15 Mp and like in the above examples, the first stage of construction will have to include 2 runways and a passenger terminal ~20 Mp.
