- The possible constraints on capacity at Dabolim, especially in comparison with Gatwick Airport, which services nearly 35mn passengers with a single runway. It turns out that constraints at Dabolim, if any, are surrounding the availability of land for larger terminals, aircraft stands, and other items like car parking and fuel tanking.
- It showed that there is a massive increase in the number of airports in our vicinity that will soon be able to handle A-320s/B737s.
- It looked at the alternatives facing Goa. The two airport option is the worst of all worlds. If we put Dabolim head to head with Mopa, Mopa is clearly inferior to Dabolim on many counts. Only if there is an overriding hard constraint on expansion at Dabolim should Mopa even be considered.
- A look at the map showed that there are significant parcels of land available in and around Dabolim for the Navy to move its non-critical infrastructure (housing, etc.), and for the Civil Enclave to expand. There is substantial land available for any food processing park that is being bandied about.
- Lastly, it speculates about why the state of Goa has got stuck with a second airport, which has not been justified in any rigorous fashion.

Mopa and Dabolim - After the ICAO 2007 Report
Thursday, April 18, 2013
Dabolim air traffic monthly data since April 2006
Some takeaways for Goa :
- The peak traffic of 13,688 passengers seen in Jan 2013 is equivalent to only around 5 hours of peak traffic for the new terminal. Therefore, we can reasonably expect the new terminal to handle a doubling of air traffic at Dabolim - 8 hours of peak traffic and the rest spread through off-peak times. Remember, the ICAO Report stated that neither the runway nor the cargo load projections acts as any constraint on capacity at Dabolim.
- Domestic traffic is an increasingly important part of the overall traffic. Projections that Mopa will see extraordinary international traffic isn't borne out by the data.
- Domestic traffic is much smoother - it doesn't dip very much in the monsoons. This is not the case for international traffic, and represents a missed opportunity for Goa tourism.
- Passengers per flight (movement) is much more variable for the international traffic. Presumably, this reflects the fact that 747s are used only for the tourist season.
- International cargo shows a correlation with the tourism season, indicating that charters are taking on cargo also.
Please put any requests for additional analysis or charts, or observations on the data in the comments below.

India air traffic annual data by airport since 2006-07
Some takeaways for Goa :
- Goa accounts for a tiny proportion of Indian air traffic.
- Traffic is heavily skewed towards domestic traffic. Cargo has somewhat of a balance between international and domestic cargo.
- The rate of growth of the traffic fluctuates a lot. It seems to be doubling every 7 years or so.
- It is only on the seat load factor that Goa is on the top 10% of the Indian airports.
- Three airports in Kerala, viz., Calicut, Cochin, and Trivandrum have higher international traffic than Goa.

Key paras from ICAO 2007 Report
The ICAO Report in 2007 can be downloaded here. If anyone has the Reports by ADPi, GTA/Vienna reports, Louis Berger or Ammann & Whitney , please contact me. Likewise, if there's any knowledge of a master plan for Dabolim / studies by AAI on either Mopa or Dabolim.
There are a number of interesting paras from the ICAO report that I quote below (selection mine, all favouring the continuation of Dabolim and not creating Mopa).
Note the objective of the 2007 ICAO report is to examine the feasibility of multi-airport strategy.
"Before proceeding further with the construction of a new airport at Mopa, the Government of Goa decided to study the feasibility of simultaneous operations at Dabolim and Mopa airports and requested ICAO to undertake the study."
Note that a key assumption around Dabolim is that there would be no further development ! And that the Government of Goa has decided to go ahead with Mopa, so no review of that decision.
"The study will be based on the following assumptions:
- Dabolim airport will continue to exist in the foreseeable future as a naval airport and that beyond the currently planned developments for civilian use, for which 6 acres of land are to be released by the Ministry of Defence; there will be no further substantial development for civilian traffic in the foreseeable future. This limited scope study is not intended to be a techno-economic feasibility study for the development of Dabolim airport to continue to serve as the sole airport for Goa for civilian operations.
- A decision in principle has been taken by the Government of Goa to construct a greenfield airport at Mopa site."
From the one line conclusion, it is clear that IF additional land is made available to AAI at Dabolim, Mopa will never be required.
"There is no question that a new airport will eventually be required at Mopa, when the enhanced capacity of Dabolim will not cope with the demand. The challenge is to determine when this capacity will be reached, assuming no additional land will be made available to AAI, and therefore, when the new airport should be commissioned, with what airport characteristics and with what capacity."
