Increasing lift without increasing drag? Are you rewriting basic physics and aerodynamics?

Maybe we shouldn't use them on cat shots then, if they add so much drag. There also appears to be a problem with the FCS because every time I get slow the flaps come out, if they add drag that could be really dangerous too.

@bbrz is right about using flaps and drag to lift ratio using different flaps setting, just to give you basic idea about ground roll on B737 using flaps 30 and 40, have a look at the diagrams below.

The higher flap setting, the shorter ground roll is.

That's why flaps are set to *half* for takeoff, and *full* for landing.

To get back to my original question. I would really like to know why ED puts this into the wish list instead of the bug section.

The landing roll is more than 50% longer than it should be, so I'm curious why this is considered to be correct?

Sorry, I should have said flaps increase parasitic and induced drag as well as lift. I can't say whether this is modeled in DCS or not.

Default Hornet wheel brake effectiveness

Hornet deceleration on ground with wheel brakes (anti skid on) is quite low on a dry runway. If someone has access to landing performance tables for the plane, it would be nice to test her against it. Wheels leave skid marks on the runway, still it decelerates as if it was on ice.

Yeah it stops like a greased duck being thrown down a slip-n-slide.

The braking feels super ineffective to me too, but I have 0 flight hours in real hornets. It feels like it's one of the least effective modules when it comes to stopping power.

Again, speaking from 0 hours of experience in the real thing.
