Ok I'll see what I can answer of this.
Here I am again, with some really strange questions this time.
1. In Microsoft flight simulator 2004, when you fly a helicopter faster than 110~130 knots, it's starts to vibrate,it happens in real world? and if it does,why?
I think that's because of software limitations or errors in the file that dictates the specific add-on helicopter, however vibration or oscilation can probably happend in real life too under some circumstances.
2.how do you take off with those thing without sending the helicopter turning around itself REALLY fast?
By liftting the collective really slowly and get a feel for when the helicopter starts to become light while making sure the torque-pedals are precisely compensating for the torque from the main rotor. Some helicopters require manual adjustment depending on how much thrust the rotor is giving, I heard other helicopters automatically adjust that, I think. Basically, the higher you lift the collective, the more you need to press down on one fo the pedals to keep the helicopter fuselage from turning (yawing).
1. Are the season is the same all over the world? i mean,here it's summer,does this means everywhere it's summer?
Nope, under equator it's the opposite, just ask Gibbo.
2.in USA,is there something like border between each state?
I'm not sure about this but I think there's just a sign or such, no border or borderpatrol.
3.what is the northest airport in the world?
Sorry, no idea, but it might be on Greenland, but then again, it might not be, however I'm pretty sure someone else here probably knows.
4.where does coke have the best taste?
By coke do you mean any soda or Coca Cola specifically (I've heard that besides "soda" and "pop" then some places in USA use "coke" as any soda and not just Coca Cola). In any case, my oppinion is any fridge that's really cold
Oh,and if you know any interesting place to fly in,can you tell me? (would be glad for their ICAOs) i've seen all Israel ten time,landed and took off everywhere and I'm looking for new things.
thanks
Hmm, interesting can be a lot of things, but sadly I haven't really been to that many airports so I wouldn't know, but I'm sure several others here have tons of suggestions
