New Flight Paths From Chiang Mai Airport?

[Robbogeordie]

Anyone know if the planes flight paths been permanently rerouted?

Huey Teung Thao and Maejo seem to be right in the path line now. Used to be peaceful and now there are planes flying over at all hours day and night.

Did you check with air traffic control?

does this look like they are over your location?

i don't know about chiang mai but at some airports if the prevailing winds change direction the landing and takeoff directions are reversed. or it could just be a huge increase in flights.

how long has this been going on?

There were no planes at all before, just the occasional hot air balloons! The planes started flying over about 2 weeks ago, every day since then. Starts about 6am and goes on until midnight.

 

Thanks for the flight tracking link.

Yes, it does.

The planes are flying north inside the mountain range over the conference centre, Huay Teung Tao and starting the turn just past there towards Maejo direction by the look of the map.

Looks like a published SID, maybe the prevailing wind is such they use runway 36 for departure / arrivals for the last couple weeks.

Here's another fun site where you can follow planes live as they come and go.  Click on any plane to give details about that specific flight.

The AA Chiang mai to Hong Kong around 6am has always gone out over Mae-Jo, I see it every morning while walking the dogs. Been doing it years.

We get a thread like this a few times a year. Somebody heard airplanes, nothing new.

They can’t be changed without new runways............a plane must take off and land INTO the wind, that is what dictates the air traffic to have the wind direction best suit the existing runways

[millymoopoo]

Chiang mai (CNX) airport has only one runway, alignment, north - south.

Usual pattern (prevailing winds) is landing in from the south, take off to the north.
If you've ever been to Big C or Home Pro at the corner of route 108 and Somphot Chiang mai rd you will feel them landing as they seem to be only 50ft above you.

Take off to the north is always with right hand turns because if they turn left there is a large lump in their way, Dio Suthep....!

If there is a wind change that causes a runway change, the reverse will apply.

Therefore areas to the south and north/north east of the airport will be effected by aircraft noise.
There is less noise with landing (lower engine power settings) but it has a shallower glide slope, (closer to the ground). Take off is noisier with max engine power settings but steeper climb (further from the ground), thus the take off noise footprint is probably about the same as the landing.

And obviously areas closer to the runway are effected more.

Check out flight radar, https://www.flightradar24.com/airport/cnx it shows a map of Chiang mai with aircraft movement tracks overlaid in real time.

Thus if you open the website when you hear the noise it will show you the offender.

I have never even seen runway 2

 

I really must get out more

These are the regular flight paths to/from CNX. In addition, flights head north to Pai and North West China, also west to Mae Hong Son. Could the extra flights be "rain making" planes?

[chingmai331]

Those 'rain maker' planes may be propeller powered since they need to go slow to stir up the clouds and drop the dope.

I do see propeller planes coming and going from CNX.  Some seem very like the old DC3, but this is a modern country so that cannot be correct.

Every landing right hand wing has passed two hundred feet above my house for the last four years since I moved from San Sai maybe they just want to annoy you now????

[cnx355]

I am living between Hang Dong and yhe airport and usually I watch most of the planes landing almost over my house wuth the landing gear down.  Over Big C 2 minutes later.

 

Usually take off is the other way over Mae Jo but if the traffic islight they make a hard right turn after take off and go South.

 

During bad weather I notice they sometimes land in the other direction from North to South.  

[Dazinoz]

I used to live in Brisbane Australia which has one main runway so can take off/land either way due to prevailing winds. To "share" the noise around they would take various flight paths at various times. There is even a website that has the outputs of noise meters placed around Brisbane in the various flight paths. Obviously can't do too much about immediate take off/landing zones but just before landing and soon after takeoff flight path can be, and is often altered.

 

Could be doing that here but I doubt it.

Even a small variation in temperature has a significant effect on aircraft climb performance. It may be that aircraft are taking longer to reach their safe turn altitude and going an extra mile or two before turning  thus taking them over Mae Jo, whereas before, they turned inside the outer ring road.

Interesting that since the very wet weather in the the last couple of hours the flight tracker site shows that most of the planes are turning much earlier, well before the outer ring road.

Where do the left hand wings land?
