Morning
.20, on first run operating Mode is always 'Demonstration Mode'. I have to close and restart OPUS and all is well. All versions up to this one have been OK on the first run

Thanks

? Друзья! £ меня такая проблема в Opusv6. PMDG 737 NGXu с трудом занимает эшелон по причине высокой температуры ТАТ. И я уже не помню, как она решила. При включении погодника REX Sky Force для P3D v4 температура ТАТ, как и должна, становится чуть меньше SAT. Opusv6 при температуре за бортом - 50 грд. С ТАТ -3 грд. С. Такого быть не должно. Что необходимо исправить?

Friends! I have such a problem in Opusv6. The PMDG 737 NGXu barely holds the line due to the high temperature of the TAT. And I don’t remember how she decided. When you turn on the REX Sky Force for P3D v4, the temperature of the TAT, as it should, becomes slightly lower than the SAT. Opusv6 at a temperature overboard - 50 TAT -3. This should not be. What needs to be fixed?

The TAT should ALWAYS be higher than the Ambient or OAT (SAT) as it takes account of compressional heating of the air molecules as they are brought to rest. The amount of heating is proportional to the square of the air speed. So what you say doesn’t make sense.

Weather engines do NOT inject the TAT. It’s a purely calculated value.

I have already told you, you must first check the weather has been injected correctly before flight by comparing the opus Local Report with the ATIS at the aerodrome.

Then monitor the OAT (SAT) ambient and target values as you fly and climb to make sure the sim is attempting to meet its targets.

The ONLY reason for an unusually high TAT, one that’s +20C greater than the OAT is when the actual temp targets are not injected or maintained. This normally happens when the sim ONLY has the surface temp to go on and no temp targets injected.

You can also examine the GRIB report to see what OAT targets are in use. Check your weather injection yourself, no one else can help you as the TAT is a calculated value within the sim.

It measures compressional heating of the air molecules as they are brought to rest, so it can NEVER be lower than the OAT (ambient temp).

So check your weather injection. Check the sims ambient OAT compared with the target value (shown in the opus weather reports, local or destination etc.).

Make sure you never disable the weather updates, never modify the sims weather, and never have multiple weather engines active, even any DLLs active.

If the ambient or OAT is reasonable then there’s no reason for the TAT to be wrong. So check the opus weather report and see for yourself what the Ambient is compared with the Target Temp.

Reporting just the TAT is pointless as it is not specified by any weather engine. The OAT (Ambient) is all that matters.

TAT: Total Air Temperature. This is the SAT (Static Air Temperature) PLUS the temperature rise associated with high speed flight. So what exactly is the temperature (ram) rise and do we need to know what it is? Actually, yes we do….

The ram rise is the result of heating due to air friction and compression. Think of it as the temperature that the aircraft skin feels. Ram rise only becomes a factor at speeds above approximately 200 kts and is proportional to the aircraft speed, so the faster you’re flying, the higher the ram rise. At jet speeds of .80 Mach or higher, the pilot can expect a ram rise of about 30 degrees C, a significant increase when considering flight in icing conditions.

Hence, a TAT that is 20C to 30C higher than the ambient air temp (OAT or SAT) is perfectly normal.

Anything in excess of this would indicate that the sim is NOT meeting its targeted ambient air temp. So this is what you MUST check.

What is the target compared with actual OAT. It’s the only question that makes sense.

That’s why I have asked you to monitor both in our on-screen Local Weather Report as you climb.

it’s actually proportional to the square of the air speed so rises quite rapidly as your air speed increases to the cruise speed.

Хорошо. SAT = - 38, а TAT = -8, это норма?

Looks OK to me, I assume you are at cruise speed in a jet.

For the weather injection it’s the Ambient (OAT or SAT) that matters. If the sim is keeping roughly to it’s targeted Ambient or Outside Air Temp then it’s calculated TAT should be fine baring an in-sim calculation error, which everyone would soon notice.

The TAT will ALWAYS be higher than the Ambient OAT as it takes into account how hotter the air molecules will become when brought to rest. It is dependent on the air speed squared ! So in Concorde the TAT will be very much hotter than the OAT. In a jet airliner at cruise speeds the TAT will also be much hotter than the OAT. In a fighter jet even hotter.

20 to 30C warmer is quite normal.

Я знаю, что температура ТАТ выше температуры SАТ. Меня начало смущать то, что я очень долго занимаю эшелон полета. Раньше такого не было. Так как у меня это уже было года четыре назад, поэтому я обратил внимание на температуру TAT. Спасибо за внимание. Буду наблюдать дальше. Сейчас я лечу над новым для меня районом (Южная Америка) и может есть отличие в температурном режиме от моего региона. Хотя ???  Talk to you later.

I would still advise for a while you monitor our on-screen Local Weather Report. At the bottom of this report it will show you what the current Ambient Air Temp Target is along with the Actual OAT (and sims calculated TAT).

Make sure the sim is doing a reasonable job of keeping to its targeted Ambient Temp.

Note, the sim may adjust its ambient conditions (wind and temp) depending on all the injected targets in its current region or local area. Hence, it may move slightly away from the current target wind and temp due to other nearby wind and temp targets.

Also make sure you have downloaded and using the latest release as we found the sim didn’t like injecting theme weather via the PDK.

The normal procedure for checking the weather generation and injection is ok is...

1. Open our Spy window. Open the Opus Weather dialog, specify your Destination and Live Weather then click on Full Weather Relod.
Make sure Spy shows successful GRIB and METAR data is downloaded.
After the weather is generated and injected (you should see that on the screen).

2. Open the Opus Local Weather Report and compare the Opus weather with the sims ATIS report. The ATIS should match the generated weather. Then ...

3. After takeoff continue to monitor the Opus Local Weather Report and check (above 4000 feet) that the sim keeps roughly to the targeted ambient wind and temp.

If all the above are OK then the sim should do a good job of maintaining the calculated TAT.

Stephen

Hi Stephen,

Just updated to V6.00.20 and all is fine other than no ai aircraft showing on the Live Map either from P3D4.5 generated or from UTLive. No other issues that I can see other than that.
I'm obviously missing something here but I wonder if you can throw me a line. FSUIPC V5 is installed and simconnect appears OK. UTLive knows where P3D is so, despite various options checked, I'm afraid I have to resort to bothering you with this.

Much appreciated if you can help.

Regards,
Richard.

For AI aircraft to appear on the LWA Map make sure you have enabled them in the Opus Config dialog and also enabled them in the LWA Map Options dialog.

I assume you mean upgrade to v6. It hasn't been finalised yet but v5 users can for the time being install and run the v6 software. This is a time limited feature probably lasting until the end of Feb.

Stephen,

Is the Selective Update functionality working on client PC's yet, or is it still limited just to the server?

Regards

Simon.

it’s limited to just the server as described in the Announcements. I will soon be posting an update that extends Selective Updates to include the Relocated Weather option. After which I will be working on communicating selective update data and operations across to client systems. It’s mostly a case of communicating the data and synchronising the operations.
