Can you put the route in here in your next post ?, I would like to try it.

Here go:

 

ROUTY T123 UDLET UR401 KURTA N563 ADV M318 MIADA

all match with the flight plan in PFPX.

 

this is the flight plan I got from pfpx which is different to yours?

 

UTAL1B UTALI T124 UDLET UR401 SUHIL R401 KURTA N563 ADV M318 MIADA MIAD1B

Upsss, sorry, i fogget SUHIL, here go again:

 

ROUTY T124 UDLET UR401 SUHIL R401 KURTA N563 ADV M318 MIADA

 

Anyway you can check the route in my post #9

Because i foget to write SUHIL R401 in my last post you may think i set a wrong route in the FMC... NO

 

First, is imposible to enter this route on the FMC:

 

ROUTY T123 UDLET UR401 KURTA N563 ADV M318 MIADA

 

 

Second, lets imagine i set a wrong route: It can make the plane stop to follow the magenta line and do crazy turns in a random course as you see in the pictures reported in post #30?

Because i foget to write SUHIL R401 in my last post you may think i set a wrong route in the FMC... NO

Thanks. But please, continue after UTRON, the problem is not allways in the same waypoint.

Increase the simulator speed if you need.

 

Before someone say nothing, i ALWAYS fly with normal simulation speed. I just increase the simulation speed for test this bug. I know increase the simulator speed may cause problems. But is not the case.

no worries always fly normal speed, will fly normal  just to be  sure

Ok, i just want to save your time, Thanks.

Ok, i just want to save your time, Thanks.

its ok  got nothing  else  to do    besides  want  to rule  out  the sim simulation speed

Thanks. But please, continue after UTRON, the problem is not allways in the same waypoint.

Increase the simulator speed if you need.

 

Got the same issue plane started to turn left as well but at the waypoint "IMKOT" tomorrow night will manually  enter  the flight plan in and  see  if  get  the same  results  at IMKOT

Thanks for your time and report

 

This bug seems to happend in a random waypoin of airway UR401

I am sure you will get similar results with flight plan manually enter.

 

Time to open a suport ticket

Peter, are you using FSX like me?

I had the same problem on a flight from VHHH to ZMUB a couple of days ago on the particularly northerly segment.  I think the earlier poster was correct in identifying this as the problem that existed on the 777 at RTM (not handling paths that were north/south).  I had to switch to HDG and bring the flight back on to the track.  This was in the PMDG 737-800.

 

I remember one time in IVAO i was checking the flights arround me, and i see one of them go complete out of route in a long flight from Jakarta to Hong Kong.

Now i understand what happend to that user... this bug not hapend only in the route from FSIA to OMDB

Try this flightplan

ROUTY1A ROUTY UDLET UR401 IMTIP UR401 UTRON UR401 GILID UR401 IMKOT R401 AXINA ETLAX AMPEX UR401G EPSIV UR401G EVEBU UR401G EKBEL UR401G SUHIL R401 KURTA N563 ADV M318 MIADA MIADA1B

 

Try it without any form of ATC. Just load the route and get your navigation system to fly it. If it doesn't then there are two posibilities. 1. one or more of the waypoints are not in your database for example there is also a ROUTY  in the Northern Hemisphere at Pos: N43:9:0.000, W117:0:0.000

2. Your navigation system is not able to cross the Equator.

 

You could also try this fpl which is Rnav only
