Greenside Posted July 16, 2012 Share Posted July 16, 2012 In the last few weeks we've noticed regular flights passing over Nong Hoi - usually departing but the occasional one that looks as if it's going to do a landing from the west. Did something happen to make them change the flight paths? Link to comment Share on other sites More sharing options...
WinnieTheKhwai Posted July 16, 2012 Share Posted July 16, 2012 You can't land form the West as the runway is North-South. Mostly planes take off towards the South and land towards the North, but if there are different and strong winds that this can be reversed. Of course after taking off to the North, (and with a mountain on the left), planes will need to do a right turn, as most flights go South. Link to comment Share on other sites More sharing options...
ARISTIDE Posted July 16, 2012 Share Posted July 16, 2012 Every time when I look down below when the plane approach the airport I see Hang dong road. Link to comment Share on other sites More sharing options...
eyecatcher Posted July 16, 2012 Share Posted July 16, 2012 I notice in high season many many flights taking off in a northward direction, but now only a few a day. Then they do their U turn and head south. I dont see flights taking off southwards(because of where I live) but in high season do they come in from the south and exit through the north so its safer with all the air traffic.

Paagai Posted July 16, 2012 Share Posted July 16, 2012 Mostly planes take off towards the South and land towards the North, but if there are different and strong winds that this can be reversed. Departures to the North are usually to de-conflict outbound and inbound traffic rather than anything to do with the wind. Link to comment Share on other sites More sharing options...

After a *very* hairy landing, the pilot remarks "dam_n, that was a short runway". The Co-pilot remarks "To be sure, but look at the width of it!" 3 Link to comment Share on other sites More sharing options...

Have a look at this link http://en.wikipedia....traffic_pattern Yup.. Planes taking off Southbound almost immediately do a left turn to take them out of the way of approaching traffic. And they quickly gain a lot more altitude than planes that come in for landing too, of course. If there's really a conflict it's just a matter of waiting a couple minutes, which happens on occasion.

eyecatcher Posted July 17, 2012 Share Posted July 17, 2012 I still think the northbound exit is used heavily in high season though and that must be due to interest of safety for incoming flights from the south. As I said before, not many coming north at the moment. Thankyou for the link on wiki; we have all just gone from mere plane spotter to being able to discuss the aerodynamics and wind turbulences at take off and landing.

WinnieTheKhwai Posted July 17, 2012 Share Posted July 17, 2012 High season is also the cool & dry season, which has different weather. (And no wind to speak of) Link to comment Share on other sites More sharing options...

Sorry but Wini is confusing Approach with a traffic pattern.... CNX has a standard approach to Runway 36 since this is their ILS runway. Takeoff is normally traffic dependent, when their are a lot of aircraft on approach the takeoff will be on Runway 36, when there is seperation between aircraft they use Runway 18. The only time that wind becomes a factor at CNX is if the crosswind exceeds the maximums then the runways would close..... hard to imagine since the typical wind patterns are generally out of the North or South in Chiangmai. 2 Link to comment Share on other sites More sharing options...
uptheos Posted July 17, 2012 Share Posted July 17, 2012 (edited) Planes seem to be taking off and landing without too much bother.

Single runway.... depending on which way you takeoff it can be either 36 (North) or 18 (South). For landing, if it is an Instrument approach you will be on 36. Non-instrument approach can be on either runway (Direction). Link to comment Share on other sites More sharing options...
threedot Posted July 17, 2012 Share Posted July 17, 2012 well now I want to know if we are on runway 18 or 36. I didnt realise there were this many runways here. There is only a single physical runway with two directions. If there is a big mountain on your left, you are on 36, heading north (360 degrees). If there is a big mountain on your right, you are on 18, headed south (180 degrees). Link to comment Share on other sites More sharing options...
