CNX Airport early 2025

[sqwakvfr]

1 . CNX is a single runway airport.  RWY 36-18  is 11,000 but the actual usable portion is less.

2.  The terminal and gate areas are very crowded.  I took an international flgiht in Jan and Feb 2025.  

3.  The combination of domestic flights and now growing number of international flights has me concerned.

4.  Have been a commercially rated pilot for 20 years but I have never worked for an airline.  But I do have a good understanding of the limits of busy single runway airports.

5.  Here are some of the international flight that land and depart from CNX:

      Asiana, to Incheon, Air China to PEK, Cebu Pacfic to Manila, China Airlines to Taipei, China Eastern and Southern to the ROC, Easter Jet to S. Korea,

      EVA to Taipei, HK Express to Hong Kong, Jeju Air (still flying for now) jin Air-Incheon, Korean to Incheon, Scoot to SIN, Starlux to Taipei

       Viet Jet to Oasaka and lastly Air Asia to KL(2x a day). 

 

       This list is not compete and even Eithiad has plans to start service in late 2025.

 

These are a lot of international flight for CNX and some of these carriers do not fly everyday.

 

Here are my main concerns:

 

1. One runway incident will knock the airport out of commission. The nearest alternative airport that can handle the traffic is probably 

     BKK or DMK.  That is a long away to get back to Chiang Mai via car, bus or train. 

2.  All airport runways need to be inspected and maintained on a regular basis. This means the runway has to be closed.  Inspection and 

      maintanence should be conducted during the day.  I have never heard of this airport being closed for inspection and maintanence.

 

I believe CNX airport is at or beyond capacity for safe operations.  The time to build a new airport is anywhere from 3 to 5 years from start to finish.  Everytime an

airplane lands small amounts of rubber from the tires are left on the surface.  This rubber has to be removed to ensure safe landings. This can take hours to complete.

If there is availabe land a faster solution would be build a second shorter runway that is parallel to RWY 36 to 18.

They must be doing something right I fly in and out of there 2 times a month.  Rarely a delayed flight or long wait on the runway.

They talked about Lamphun, but doubt that will happen.

If a person is worried, then the train Is an option.

   What about Chiang Rai airport ?

Possible but Korean Air flies an A330-300.  This aircraft could be a challenge but is their an Immigration unit that can handle international arrivals?

Everything is ok until somethings happens.   Train to Busan?

Apparently airport officials don't have you on their list to notify of inspection or maintenance procedures. Pure speculation on your part..

 

Having flown from a raft of major airports in the US (and other countries), to this day I've never seen one of those airports close a runway during the daytime to remove, as you say, "small amounts of rubber." 

 

The last serious accident at CNX was, I believe, in 1967, and the accident occurred here but wasn't related at all to airport safety.  I see no reason to have any significant safety concerns regarding CNX.

CNX ought to be able to handle way more aircraft movements. Gatwick in the UK handles at least 3 times as many take-offs and landings per day, is closed for part of the night (unlike CNX) and is a single runway operation. So correct investment in equipment and staff can handle far more traffic than now but the terminals are unable to handle much more throughput so the planned rebuilding is crucial.

LAX has 4 runways and the 24R is where most of the international flights land and on a regular basis the runway is closed for inspection and maintenance. Several times a day Airport Ops personnel will drive down the runways to conduct a FOD check. FOD stands for Foreign Object Debris.

You have suggested that CNX is unsafe and also are suggesting that CNX does not comply with the ICAO requirement of a daily daylight inspection of runways for foreign objects. Perhaps you could share with us how you know (if you do) that CNX doesn't comply with that standard.

You forgot Chiang Rai 🤗

But Gatwick has 2 runways.  They are too close together to use simultaneously, but the second runway is there in case of an emergency or maintenance on the other runway.  You completely missed the OP's point that Chiang Mai has no backup runway.
