F-18 Altimeter settings

[Kazius]

Was toying with dynamic weather and set it for anticyclone multiple systems and ended up with an altimeter adjustment to 32.42 on the QFE indication in briefing. However, I noticed the hornet stops at 31.00 Is this standard or something that I should report as a bug?

[Kazius]

So is 32.42 a highly unlikely pressure setting that the dynamic weather system is creating?

[Kazius]

Thanks for responding, I will hold off using dynamic weather until they implement something that more accurately represents real weather pressures then :)

[Kazius]

I didn't do anything. I setup dynamic weather, 12 degrees celcius. 6 weather systems anticyclonic. It generates the systems automatically. I go into the game and the game tells you in the briefing what the QFE setting is.

 

Calm down a bit, telling people they need to take a class because they don't know what they are doing is a bit rude when it is the dynamic weather system in the ME that generates the systems automatically.

Sorry, I assumed someone who was replying to the thread understood when I mentioned in my first post that I was using the dynamic weather system and that they knew about the dynamic weather generator in the mission editor and would know that it sets the pressures itself. I apologize if you didn't know how the mission editor works.

[Kazius]

Oh look, there is currently 6 systems surrounding Utah. Each one is going to be interacting with each other.

 

 

If you play with the dynamic weather generator you don't see all systems on the map. The edge of 4-5 of the systems are usually on the outskirts interacting with the area.

 

Anyways, I have learned that the dynamic weather generator in the mission editor doesn't work accurately and that was the determination of this post. Thanks for answering the question regardless.

Hornet was never designed with QFE operations in mind although the normal problem is that the altimeter can't go low enough for QFE of a high elevation airport. QFE is always less than QNH unless the elevation is below sea level.

 

Yes, 32.42'' is a crazy. The highest record pressure in history was 32.01''. Dynamic weather loves very high pressure deltas. If you're not familiar standard sea level pressure is about 100,000 Pascal so 1,000 is a deviation of 1%. The record-breaking weather would be 3-3.5% above standard. +2% might be something a pilot only sees once in his lifetime.

 

When you use the ME dynamic weather you can type in your own pressure deltas. You probably want to keep it +-300 to 1200 Pa from standard and if you have multiple system centers keep them closer to each other. 800, 1100 or or -100,300 500,750 is good. -1100,+1400 is going to be nuts since there is 2500 Pa difference between two systems that are quite close together geographically.

F-18 Altimeter settings

 

I’ve notice the wx presets in the sim isn’t well designed. For example, create a fast mission with rain and you get a pressure of 29.12, precipitation with a few clouds. Not even broken ceilings. Sorry, but I’ve never seen a pressure that low in the northern hemisphere on a typical day. Sure you may find that in the eye of a hurricane/typhoon, but that’s not realistic in any standpoint for what we use the sim for.

 

I personally stay away from those presets. Just make it yourself.

so i'll just ask.. what are typical pressures?

Lowest I’ve seen not including a hurricane or tropical storm is 29.40-.50 and as high as 30.30-.40. Beyond those limits is really abnormal. Remember, the wx in the sim should also affect the engine performance as well. That’s why I never use the presets. Not realistic, hinders the awesomeness.

 

Addendum: just noticed the analysis posted. Doing the conversion the lowest low is 29.29. Highest high is 30.33. I remember seeing a fast mission generate a pressure between 28 and 29 inches. Winds were normal, no thunderstorms, granted there was rain. Just seemed inaccurate. Pressure that low should be tropical storm. Hurricanes get really low, and would definitely be evident in the sim if done correctly. Lowest recorded was 26 to 27 inches! Category 5 of course.

Well you should have said that in the beginning, You didn't. You caused this.

Sorry but this is just :megalol:

It's literally his first sentence to which you answered, so he didn't "caused this"... ;)

 

But thank you very much for your explanation Trev :thumbup:

And yeah packing 6 weather systems into maps this size is insane. I can't imagine what that would look like in real life. That would be like the weather in Halo Ring #4. Snowing over here, tornado over there. A single cyclonic or anticyclonic system will be like 600 to 1200 miles in diameter. Why 6 systems is an option is beyond me.

 

I'm just talking from real world. There's a lot of goofy stuff in that mission editor.

 

Hahahahahahaha :megalol:

[macedk]

The mission editor is inaccurate ??? . no way man ;) just no way :)

Not the editor, it’s the created presets. To different things. The create fast mission uses those presets too.
