First, the ATIS at RJGG: I start ASN weather first and then P3D, so I expect P3D to have to correct weather atm startup. The PF3 ATIS gives me RWY36 with winds 160/06 and the correct QNH. Later, the Taxi instructions are for the RWY18, so correct.

So PF3 did the correct thing with the weather information it received from the weather station,
but:
13-5-2016 14:05:54: 620 - Wind_Surf_Dir=160 Wind_Surf_Vel=6 rwyClouds = 0 Cloud_Low_Base = 0
... lots of Wind_Surf_Dir=160 ...
13-5-2016 14:13:01: 350 - Wind_Surf_Dir=160 Wind_Surf_Vel=6 rwyClouds = 0 Cloud_Low_Base = 0
13-5-2016 14:14:42: 580 - Wind_Surf_Dir=298 Wind_Surf_Vel=6 rwyClouds = 999999 Cloud_Low_Base = 0
13-5-2016 14:14:45: 610 - Wind_Surf_Dir=160 Wind_Surf_Vel=6 rwyClouds = 999999 Cloud_Low_Base = 0
... lots of Wind_Surf_Dir=160 ...
Takeoff happens at 14:36:42, now Wind_Surf_Dir starts to change
13-5-2016 14:36:48: 940 - Wind_Surf_Dir=160 Wind_Surf_Vel=6 rwyClouds = 10535643 Cloud_Low_Base = 0
13-5-2016 14:36:51: 040 - Wind_Surf_Dir=161 Wind_Surf_Vel=6 rwyClouds = 10535643 Cloud_Low_Base = 0
13-5-2016 14:36:55: 740 - Wind_Surf_Dir=162 Wind_Surf_Vel=5 rwyClouds = 10535643 Cloud_Low_Base = 0
13-5-2016 14:36:57: 810 - Wind_Surf_Dir=162 Wind_Surf_Vel=5 rwyClouds = 10535643 Cloud_Low_Base = 0
13-5-2016 14:36:59: 880 - Wind_Surf_Dir=163 Wind_Surf_Vel=5 rwyClouds = 10535643 Cloud_Low_Base = 0
13-5-2016 14:37:01: 950 - Wind_Surf_Dir=164 Wind_Surf_Vel=4 rwyClouds = 10535643 Cloud_Low_Base = 0
13-5-2016 14:37:44: 140 - Wind_Surf_Dir=222 Wind_Surf_Vel=3 rwyClouds = 10535643 Cloud_Low_Base = 0
13-5-2016 14:38:05: 640 - Wind_Surf_Dir=225 Wind_Surf_Vel=3 rwyClouds = 10535643 Cloud_Low_Base = 0
13-5-2016 14:38:08: 220 - Wind_Surf_Dir=261 Wind_Surf_Vel=5 rwyClouds = 10535643 Cloud_Low_Base = 0
13-5-2016 14:38:10: 770 - Wind_Surf_Dir=265 Wind_Surf_Vel=5 rwyClouds = 10535643 Cloud_Low_Base = 0
13-5-2016 14:38:13: 330 - Wind_Surf_Dir=269 Wind_Surf_Vel=5 rwyClouds = 10535643 Cloud_Low_Base = 0
13-5-2016 14:38:15: 890 - Wind_Surf_Dir=274 Wind_Surf_Vel=5 rwyClouds = 10535643 Cloud_Low_Base = 0
13-5-2016 14:38:18: 430 - Wind_Surf_Dir=277 Wind_Surf_Vel=5 rwyClouds = 10535643 Cloud_Low_Base = 0
13-5-2016 14:38:20: 960 - Wind_Surf_Dir=282 Wind_Surf_Vel=5 rwyClouds = 10535643 Cloud_Low_Base = 0
... further changes up to Wind_Surf_Dir=320 and later down to Wind_Surf_Dir=240 again ... |
So ...
- Wind_Surf_Dir in PF3 is directly below the aircraft, while ATIS/clearance is calculated for the center of the airport.
- The wind below the aircraft (on the ground) stays static, while the wind at the airport changes.
I assume offset 04DA is used to determine Wind_Surf_Dir (there also is 0EF2 which will produce an interpolated value) and I would assume 04DA is the most accurate value we can get for the current wind direction.
Dave, would it be feasible to use Wind_Surf_Dir (and Wind_Surf_Vel) below the aircraft as another virtual weather station and include it in the weather calculation? If the effect is weighted by distance, this virtual weather station would have a big influence for the calculated weather at the departure airport and so would reflect the weather experienced by the aircraft more closely.
Second, after passing the JEC waypoint at FL240, ATC calls 'GBXTR Contact CONTROL on 118.65'. My VCP replies with 'Traffic' and my position'. Checking in Pf3_display shows that I'm on Multicom. Hitting ZERO makes my VCP calling 'Traffic' and position again. From the list in Pf3_display I took the next CONTROL frequency, dialed it in, and pushed the ZERO. After my VCP reported as usual to control, I get a Roger from ATC. I guess all is well now (I'm still flying) but this should not happen.

The problem here is, that PF3 has a voice recording of "Multicom" only in the phrase:
pfchat234=your flight plan has been filed. Contact Multicom on |
So having the correct phrase here would require editing 238 voice files. Possible, but only little gain for much work, especially as there are various other things that Dave should work on.
If you can do this, I'm pretty sure he would include it in PF3. I have done a little bit of such editing with Audacity, but you should expect about 5 minutes work per voice file -> 19 hours.
