That Xilon dude is talking through google translate, give him a break.
His text composition might be unclear, but in this thread if you read between the lines he's making some good points.
The way i see it, what he means is that in a real aircraft there's a lot of things to do during transit to and from the target area. If SoW is in fact as realistic as we've been led to believe, with improved engine and systems management, AI and communication/command system, then it won't be boring to fly in a 1:1 map.
Seriously, if you don't have a civilian sim on your PC try to find a friend who has and fly it for a few hours, i did it a few times and it was an eye opener. Fly a small 500km route between two cities in a well-done 3rd party add-on aircraft and to keep it simple, let's even say it's single engined. Do everything from start-up, taxi and take-off to cruise, descent, landing and shut-down. Then imagine what it would be like if on top of all the stuff you have to do, you also have to worry about flak, battle damage and combat, not to mention things like multi-engined/multi-crewed birds like heavy fighters and bombers.
It quickly becomes clear that you can't manage everything at the same time. So, the only way to do it is to manage as much of it as possible whenever you have some spare time. You might be in battle but you might be able to squeeze in a few seconds to fine-tune your engine settings, or vice versa, you might be in a bomber and just as the enemy interceptors are leaving you start working on the damage reports and looking at how you can get the most performance out of your aircraft to reach the home base.
I suppose that if SOW gives us IL2-style accurate FM/DM and combat with FSX-style system and engine management options, we'll be having our hands so full that some people might be unable to perform a simple level bombing run in a scaled down map, at least until they get some serious practice into it. Think about it, by the time we'll be over the target we will be swamped with the amount of workload required and nothing will be prepared for the bomb run. This is of course where improved AI crewmembers and multiple human crewmen in multiplayer come in, which is even more fun in its own regard.
For me, the most important advantage of 1:1 maps is fuel usage along with the fact that people will be careful and fly in a more realistic manner: you can't just load up 25% fuel, take off from the taxiway and rejoin the fight 10 minutes after you get shot down. Of course, real life always gets in the way of our hobby and that's why i also support scaled down maps. When flying on servers with high realism settings and good missions, IL2 size dogfight maps are still very good and satisfying.
