Yet Another Trivia Quiz

Ok total stab in the dark 3 Spitties and 1 hurricane?

[Naki]

Yep good stab in the dark! There are currently airworthy the two Temora Spitfires (including the ex Alpine Fighter Collection one) and the two seater in Auckland (the Population is about to increase to four with the Feilding one due to fly before Christmas) - the only Hurricane is owned by the Alpine Fighter Collection.

Wohoo!

Ok my Question is: The FSX terrain system uses a modified version of the RQT algorithm.

a) What does RQT stand for?
b) Why did it need to be tweaked for FSX (i.e. What is a limitation of the standard RQT)?


(Im a terrain geek and yes, you can google

Restricted Quad Tree

By design, the RQT and ROAM algorithms reduce triangle count in flat areas (good!)
When used with a “roundâ€￾ Earth, the RQT happily eliminates curvature over the ocean (not so good)

is this good enough??

The RQT algorithm, as published, is really intended for “flatâ€￾ Earth terrain where the sea level elevation reference is assumed to be an infinite plane. Since Flight Simulator models the Earth’s curvature, we had to modify the algorithm a bit. The main problem is that the unmodified RQT tends to eliminate nearly all the mesh vertices over large open expanses of ocean which it interprets as being completely flat. The solution is to increase the error metric for each point in the mesh by the height of the Earth’s curvature above the line connecting the point’s opposite neighbors. The result is an increase in the error metric roughly proportional to the distance to its neighbors. The larger the error metric, the less likely a point will be eliminated from the triangulation. This helps preserve the Earth’s curvature in large areas with the same elevation.

Is this good enough?? Googled, copied and pasted.

Yep - Thats what I was looking for (Ill have to make it harder next time!)

Away you go!

Name the Airport

A quick one. Good one for the travellers.

[Daniel]

Um, could it be Beijing Airport?

[Njbb1995]

Was gonna say that.....

[Anthony]

A quick look at that picture's filename confirms the suspicions regarding the identity of that airport.

[kiwibarguy]

You got it Daniel, of you go! Well done mate!

Ha Ha didnt notice that!!!

Sorry for not replying earlier Ok time to get things moving again

What is the largest aircraft that has landed on an Aircraft Carrier?

[Njbb1995]

Um the C-130 Herc?

Yip, over to you
I think there are a few videos of it. It was JATO equipped.
Be a pretty cool thing to see getting of the deck.

In what year did A4 Skyhawk production end? And for bounus, How many were built?

Goodluck

Ha ha they stoped in 1979 and a total of 2,960 were built .

The idea is to have questions that you cant Google and have an answer in 5 seconds guys I think they generally have to be NZ-related too, I got told off for it a while back.

I knew that bout the A-4's before,but i know what you mean V.A.C.

RULES:
1. You post the next question if you get the answer right.
2. You may not answer for 3 goes when you get it right
3. If no-one gets it within 3 days, you must post something that someone can get right

I think of those three rules, the only one that actually applies is #1.

correct your up beaufighter guy (sorry bout the easy question )
