I really enjoy the PBY and PBN's and like to use them for AI traffic. Both of these planes takes about 2 miles to break free of the water when taking off. Because of this attitude they cant be used in IL-2 missions that would have had them flying in real life missions. Take-off's from a inlet/bay situation is impossible in most cases. My question is why does it take so long for them to break free of the water? Is this something that aircraft modders have given up on? I sure hope not.

How are you with hydroplane physics?
Do you understand that they do not use wheels when taking off or landing?
Do you understand that water has a greater viscosity than air and that tarmac or concrete doesn't wet?
In other words nothing wrong with them (if Oleg has uded correct data).
I'm referring to a simulator one that represents real life. What does your post have to do with my question? A ton of things within IL-2 such as aircraft crashing and being able to fly again for example, people dieing is another. All these things defy reality.
Do you create any of these mods? And no I have never heard of a plane that use's wheels to take off or land on water. lol

I use the PBN a lot when I play around in mission maker. I have no trouble with take offs, they are not excessively long.
If FM is accurate, then you have a few factors that cause the longer takeoff in seaplanes, such as resistance, suction and tidal movement. Wheels only have a small contact area and thus they have less resistance whereas seaplane has an entire float / fuselage area that is in the water, which as stated earlier is a denser substance. Then you have the surface tension / suction to break free from, that is why the floats etc have stepping planes on them.
Like I said in beginning, I have not had any big issues in game my self, can you describe better what you are doing and how you are trying to use the seaplane?
As I said, I am using them as AI. Can you get them to take off in a realistic manner when you use them as AI? Or do they take a couple of miles to take off.

I have used float planes in many mission for offline and have little trouble with takes offs.
When you insert them check way points and make sure you give them an Alt. to be at a giving tiime.
Set alt at first way point say at 100 M second at 500M and so on.
With out the ways points and alt set they will just be a boat.
Skyomish...since your the first person I have ever talked to that didnt have a problem with AI float planes How about posting a small mission demonstrating what you just described so that all of us can learn from it.

I would but I dont know how to do that Sir. :?
Now we're getting somewhere. So from what you say the PBY does take a lot of room for taking off. In FS2004 I would have just increased the engine HP and it would have taken off much sooner. Works for AI but not if your flying it. Can't do that with IL-2.
Guess I'll just have to get used to it.
Thank you,

Just remember the larger the load the deeper the aircraft will sit in the water in real life. This causes greater drag in the water which translates to longer take offs. Ok the max range for the PBY is 2,520 miles. With a fuel capacity of 1475 U.S. gallons internal and 1750 U.S. gallons with wing tanks. So each gallon equals 8.66 pounds, which translates to 10148 lbs. and 12040 lbs. weight. The PBY's empty weight: 20,910 lbs. with a max takoff weight of 35,420 lbs. which means you can take off with a load of 14510 lbs. So if you take a fuel load of 50% you will decrease the load to 5074 lbs. and a range of 1260 miles. With 25% fuel weight will decrese to 2537 lbs. and a range of 625 miles. So the lighter the fuel load the shorter the takeoff will be. Now this will be offset by bomb load but not as much. I would suggest 30% fuel load for short range to medium range missions.
