Smog / Haze over Kuala Lumpur: a hazard for aviation?

Post by SN30952 »

Heavy smog over Kuala Lumpur has been reported.
This recurrent phenomenon appears yearly.

A belgian university was studying the case. Look in this link: good map and picture of the problem.
I was wondering if some of LZ members have pictures and more info on that.

Indonesia Forest Fires Blanket Malaysia
Satellite images showed 587 "hot spots," or fires, in Riau and northern Sumatra in Indonesia.

You'll all remember this:
Plane crash over smog site kills 221
JAKARTA-September 26, 1997 -All 221 passengers and crew were feared killed when a Garuda Indonesia Airbus crashed on Friday in a mountainous region south of the city of Medan on Sumatra island.
The cause of the crash was not known but one resident in Medan said the city was shrouded by thick haze from forest fires in the region.

In that period (1997) the smog was so bad that: the smog had spread to 9 southern Thai provinces and the thai government on that Friday said it was prepared to send two water-carrying aircraft to help fight the blazes.
The hardest hit was Phuket resort province. There were no victims but motorists were requested to avoid driving because visibility in Phuket and some of the affected provinces was poor
.

Today, only smog reports have come to my attention, but is there real hazard for aviation, as smoke hinders considerably the visibility.

That was in 1997, Regi, but the situation starts getting threatening again.
Maybe you left HKT - smoking -, for an other reason last Saturday! :wink:

Smog hangs heavy in the air in Hat Yai, causing poor visibility and breathing difficulties.
That's for the South, in the North there is flooding.

Pai under one metre of water. Torrential rains over the last two days caused flooding in the northern provinces of Chiang Rai, Chiang Mai, Lampang, Mae Hong Son and Phayao.
In Chiang Mai, flash-floods inundated about 3,000 houses yesterday.
If that caused a fire by shortcut in Pricess hotel near the Nightmarket has not yet been determined.

I was in KUL last year in September for two weeks. Beside the very
hot temperatures the smog/dust over the city appeared already in
the morning. But no wonder, there are "millions" of cars and motorbikes
crusing through the city...

what do u expect? KUL is in the tropics, it is hot and humid. BUT the haze is not happening yearly.. mind u, though the air is not 100% clear. smog happens in any urban areas, LAX for example. and KUL does not have 'million' of cars and bikes as u may have observed. :wink:

The smog is everywhere, downtown, on the country side, even on the islands, it is due to the burning of the forrest in Borneo...
There is even smog on Phuket.

i'm sorry, but we do not actually address that as smog (smoke + fog) but it is mainly haze, and it is currently and mainly originates from Sumatra. slash n burn has been a 'normal practise' to some of the local natives, though now the respective govts of Malaysia and Indonesia are discouraging the people to do so.. and peat fire is something that happens quite frequently esp during hot and dry weather. we had a bad hazy experience yrs back, and it is recurring, but NOT the entire nation is being enveloped with the haze.

Well we have just had a meeting in KL cancelled because of the smog believe it or not - so the effect on aviation maybe the reduced number of passengers. The smog shouldn't have an impact as most jets can now land in the pretty low visibility - or am i wrong?

KLIA was opened during the HAZE, hazy period. the visibility was between, 800-1000mtr. shud it dropped below 500, then it was considered 'unfit' for flight operation.
