TOPCAT Misinterprets Weather Snapshot File

[Guest merchant]

There are issues with ASA weather snapshot file current_wx_snapshot.txt and TOPCAT. After refreshing ASA and updating the weather forecast in TOPCAT the winds interpreted by TOPCAT are not what FS9 depicts resulting in TOPCAT's calculations for the opposite end of the runway. This happened at RCTP, OMDB and HKEL.The current_wx_snapshot.txt contains the following for HKEL:HKEL::HKEL 240500Z 00000KT 9999 FEW018CB BKN260 16/12 Q1023::HKEL 251030Z 2512/2618 11010KT 9999 BKN028 TEMPO 2512/2518 VRB10KT -TSRA/SHRA SCT020 SCT080 TEMPO 2600/2606 VRB05KT CAVOK BECMG 2608/2611 08010KT BKN026 TEMPO 2612/2618 VRB10KT -TSRA/SHRA FEW023CB BKN024 BKN080::166,002,25.9/131,005,19.7/100,009,16.5/091,014,07.0/087,025,-03.9/058,007,-13.3/115,011,-30.4/133,015,-40.6/110,023,-53.3But ASA's report tab shows winds at 230 and 1 knot.I started ASV 6.5 and found current_wx_snapshot.txt contains the following for HKEL:HKEL::HKEL 240500Z 00000KT 9999 FEW018CB BKN260 16/12 Q1023::HKEL 251030Z 2512/2618 11010KT 9999 BKN028 TEMPO 2512/2518 VRB10KT -TSRA/SHRA SCT020 SCT080 TEMPO 2600/2606 VRB05KT CAVOK BECMG 2608/2611 08010KT BKN026 TEMPO 2612/2618 VRB10KT -TSRA/SHRA FEW023CB BKN024 BKN080::164,008,26.6/142,007,19.6/099,009,16.7/101,015,07.6/090,021,-03.2/057,010,-13.7/103,012,-30.5/131,013,-40.7/117,018,-53.6ASV 6.5 report agrees with the text file.Any ideas would be appreciated.TIA

Hi,The weahter files are exactly the same.Using ASA are you manually refreshing the AI system with the proper icon? In ASv6.5 this is usually automatic, but with ASA B394 or higher you must refresh manually.Thanks,

No, I have not been refreshing the AI manually. I have not installed any betas. Is there a preference to have it performed automatically?

Hi,No difference then with B316. I am not familiar with TOPCAT, but again both wx files are the same from us.Thanks,

That report isn't showing any wind!

[JSkorna 137]

Hi Kevin,If winds are calm then that is a valid entry and it is the same in both reports.FS cannot report this so it adds a direction and a speed. Anything under 6kts is considered Calm in FS.Thanks,

ASA was not showing calm winds but ASV v6.5 reported the same as the text file.Why the disconnect between ASA decoded METAR and text file? ASV v6.5 decoded METAR agreed with the text file.

Read the METAR's again. 0 kts IS as calm as it gets!BTW I use ASA and Topcat with no problem.

I am attaching a ASA screenshot as well as from TOPCAT with the winds at 9kts and ASA has the wind at 0kts.TOPCAT's weather forecast:WEATHER BRIEFING - N497MC UAE9951 HKEL-FWKI 29APR09 01:03:28ZWEATHER DATA PROVIDED BY ACTIVE SKY** NOT FOR OPERATIONAL USE **ELDORET INTL [08, 26]HKEL 281200Z 06009KT 9999 FEW025CB SCT026 BKN300 26/09 Q1022HKEL 281630Z 2818/2924 16005KT 9999 SCT020 TEMPO 2900/2906 CAVOK BECM G 2908/2911 12010KT 9999 BKN024 TEMPO 2913/2918 VRB10KT -TSRA/SHRA FE W023CB BKN024 BKN080 BECMG 2921/2924 SCT018

The ASA report tab and metar agree? I used the UPLOAD function of the forum. What is the destination when UPLOAD is used? I am using the release version of ASA (no patches installed) What is the current release version of ASA?

[JSkorna 137]

Hi,Yes, everything matched. Do you see your screenshot? I just hope I am not missing it! You can e-mail it to jim(A)hifisim.comB316 is the release build.B394 is if you have SP1 Beta 2 installed.Thanks,
