Traffic Direction Change at CNX? Seems aircraft are now taking off on Runway 18. Why?

[GammaGlobulin]

Dear Friends,

 

As far as I have been able to observe, it seems that aircraft at Chiang Mai airport are now taking off to the south, and landing on runway 18.

Why is this?

 

Is this to avoid flying lanterns due to the festival in Chiang Mai, today, or might this be a more permanent change?

 

Here is what I am talkin' 'bout.....

 

So what this means is that, for those living to the south of the airport, the noise level will increase drastically for them.

Especially, if the larger jets take off using FULL-AFTERBURNERS.....

What a pleasant thought.

 

The runway is set up this way:

 

Therefore, anyone living to the south or to the north will get BLASTED on a daily basis.

Maybe you just need to decide if you want to listen to aircraft taking off, or enjoy the sound of aircraft on final....(final approach).

These are not tiny aircraft, mind you.

And, they definitely are NOT gliders.

When one of these giant tubes of aluminum glides in.....on final....

They are NOT gliding.

 

I have spent most of my life in Chiang Mai trying to avoid the vagaries of the routing of traffic from the skies.

Sometimes they land to the South, and sometimes to the North.

Why can't they just take off to the West, I wonder?

Would not bother me if they did, even though to the West we know there are mountains.

 

I have had it with this airport noise.

I say, they need to move this airport way far away.....maybe to Lampang.

Lampang is just too quiet anyway.

Nobody likes Lampang because....It's too quiet.

If they move CNX to Lampang, then everyone would be happy.

 

So, the main question here is....

 

When, if ever, and how much longer, will this airport traffic control get back to normal?

Or, won't it?

 

Are you also kind of out-of-sorts today (and yesterday) due to this new traffic scheme?

 

Information please....

Thank you.....

 

Gamma

For most of today the wind has been coming from the South.  Takeoffs and landings are best performed heading into the wind.  It's more important for takeoffs than landings.

While I realize that this is logical, I also have read somewhere, that at these lower wind-speeds, most larger aircraft are not that much affected.

 

Also, from my experience, is is crosswind takeoffs and landings that are a bit more hairy.

 

This is why I asked the question.

 

Might it be that the guys in traffic control are just trying to keep us on our toes, just by mixing things up a bit, whenever we least expect it?

 

Also, another reason for this Topic is to advise, once more....to newcomers who are looking for a lace to buy or rent....

Perhaps they should think long and hard before finalizing their purchase...

So that they can find a place where aircraft noise near the airport will be less of an issue....

IF they are sensitive to aircraft noise, obviously.

Loi Krathong protocol?

Could be...

EXCEPT...

I noticed that later this afternoon....

Traffic Control reversed the direction of landings.

So....one might suppose....

This is not the reason.

 

I think the reason is that Traffic Control just wants aircraft to BUZZ us....

From the opposite direction....

Once in a while.

 

This is all that makes sense to me.

 

NOTE4:  By the way, I would say that anyone who intends living in one place, here in Chiang Mai, pay particularly close attention to airport related noise..IF...one hopes to retain one's sanity....as have I.

 

Also, I would say that if I had it to do over again....

I would build a house with an underground bunker.

 

Having an underground bunker, completely impervious to external noise, is so crucial for general well-being.

An underground bunker can protect us from roosters, low-flying aircraft, barking dogs, motorsickles, heavy diesel trucks, Motorsickle Gangs on their Loud Harleys, Loi Krathong Fireworks, and just SO MUCH MORE.....!

 

And...

It's all about CONTROL.

 

IF one can control the noise, then there is far less stress.

 

For example, IF one has an underground bunker...then...

Once can easily stay above ground, most of the time, and not feel stress...because...

It is this capacity to CONTROL the noise that provides peace of mind.

 

Just by having a SOUNDPROOF RETREAT, under one's house...

Then, stress is relieved.

One can, at anytime....just go underground...

Turn on one's computer, in peace and quiet, and post Topics on TV.

Also, have a bed down there, too...just in case the noise lasts for more than eight hours.

 

Yes, My Friends....

Having an underground Sound Bunker...is a Moral Imperative....to protects against losing one's mind.

 

But REALLY.....

 

I am still designing my DREAM ROOM...underground....

Something like this...

Only Quieter....

 

IMHO...  Almost NOBODY should live in Chiang Mai without a room this good, or better....

 

A room like this can protect Farang from both Noise and Smoke....

Maybe get out more and socialize with real people instead of arguing with yourself.

I asked the same question to CNX air traffic control yesterday. 

 

I got a very curt reply, the gist of which was... You live next to an airport. Deal with it. 

 

My question was why do some planes taking off to the north begin thier turn SHARP right as soon as wheels are up.... Then they end up flying right down the Ping... I live in Wat Ket. They are loud. 

 

Half the flights do indeed... Fly straight north past the Mae Rim golf course then a slow right turn south.... Then they pass over Central Festival but at a higher altitude 

 

TIT. FK everyone else, we don't care

Umh, the runway runs North South.

 

Taking off across the runway is not frightfully practical...

TOP-DOWN Authoritarian Society, is Asia.

Didn't you know by now?

 

If you want a different society, then head to the Scandinavian countries, and culture....maybe....

Yes. but....

Doing so might bring the noise to a sudden and blessed end.....

 

Abruptly.

Thank you for your support.

 

My reply was no more than a rhetorical remark confirming what you stated, and not a question.

 

I understood that you understand the dynamics of closeness to power in Asia, and distance from power in Asia.

 

So then....

 

Ours is not to reason why; ours is but to do and die....as you know.

GG stop with the faux stupidity. Its not becoming at all.

 

Yes, airplanes generally land into the wind for safety and performance reasons: 

 

 

• LIFT

  An airplane's wings rely on the speed of the air moving over them (airspeed) to lift the plane off the ground. 

   

   
• Groundspeed

  Landing into the wind helps obtain maximum airspeed with minimum groundspeed. 

   

  Landing with a tailwind can increase the risk of an accident. For example, if you're landing with a 10 knot tailwind, your landing distance may increase by 50%. 

   

  Just think about it. Rather than just pounding out more word salad. Please.

i disagree with this statement: "For example, if you're landing with a 10 knot tailwind, your landing distance may increase by 50%. "

 

i disagree, 100 percent.

Please show the data.

 

This is ludicrous, at least where commercial jets are being considered.

 

Show the data and the graphs.

 

Then, we will decide.

Probably not 50% but it can be a dangerous landing attempt. . Many years ago I was trying land a Cessna 172 at my local airport and the wind had changed from a head to a tailwind and I almsot ran off the runway. The runway was 5000 feet.  I called the tower later and asked did they notice the change in wind direction.  The tower said they woudl get back to me. I am still waiting.

Tailwind operations for commercial aircraft are probably acceptable according to manufacturers' standards, up to 10 to 15 knots.

Not probably.

The statement was taken directly from the Google AI....

And, it's nutzo, in fact.

Makes no sense.

 

Just do the Physics.....in terms of increased energy due to increased velocity, due to tailwind.

Most of aircraft landing at CNX are B737 or A319, 320 or 321 series so 10 to 15 knot tailwind should be within  performance limitaions.  To my surprise I just saw aThai Airways B787 taking off on RWY 36.  So it looks 36 is now in operation.
