Airspace Constraints
Effect of Alverca (LPAR)
Effects on Traffic Departing and Arriving
Possible Solutions
Arrivals
Departures

3. Geographical Situation

4. Neighbouring Aerodromes
8.2 NM
10.3 NM
10.5 NM
6.1 NM

5. Airspace Constraints
16 NM
8.5 NM

6. Effect of Alverca (LPAR) on Humberto Delgado Arrivals and Departures
IFR Traffic:
Blocks Departures Runway 03 and Runway 21
Blocks Arrivals Runway 21 and Runway 03
VFR Traffic (1000 feet traffic pattern)
Blocks Departures Runway 03
Blocks Arrivals Runway 21 and Runway 03 (go around procedure!)
Alverca Operations basically close Humberto Delgado and impact airport capacity

7. Effects on Traffic Arriving and Departing

8. Current Situation
Example: Simulation for Runway 21

9. Future Constrained Situation Runway 21 With Point Merge
Example: Simulation for Runway 21 – Possible Procedures

10. Possible Solutions

11. Possible Solutions
Example: Simulation for Runway 21 – Possible Procedures

12. Possible Solutions
Example: Simulation for Runway 03 – Possible Procedures

13. Impact on Restricted and Danger Areas
R42B (Sintra):
Reduced to 3500’ on eastern side
Reduced to 4000’ on western side
Possible to 6000’ (FL60) on northwest area
D10 (Alcochete):
Reduced to 8000’ (FL80) for normal operations
R60A/B (Monte Real)
8NM Corridor in East Between FL100 and FL300
R26A (Montijo):
3000’ maximum
R44A (Alverca):
1000’ Maximum? Other solution?

14. Conclusions Geographical Situation
Constrained by Other Aerodromes
Effects on Traffic Departing and Arriving
Highly constrained – straight ahead departures only
Small Sequencing Area – Runway 21
Possible Solutions
Reduction of constraints – Restricted and Danger Areas
New Departure and Arrival Procedures Allowing One Minute Between Departures
Increased Need for Airspace Re-Organisation
