Controllability during take-off and landing

[chaos]

Just wanted to call attention to the fact that, for all modules, controllability during gound operations is questionable at best. Especially during landing, it is way too hard to stick to the centerline whilst braking. It ‘feels’ like I’m landing on icy runways, even in the scorching heat of Nevada in the middle of summer.

I know this has been raised before but nothing has been done about it in all these years. Granted, it only affects a limited portion of the game but it completely breaks the immersion.

I would greatly appreciate this problem being fixed.

I know you say "all modules" but what modules specifically are you having issues with?  I have no significant problems with it in the F-18 (unless anti-skid is turned off).  If you're using toe brakes, I'd try a combined brake instead to make sure you're not getting different input.

Maybe consider some curves for your rudder axis as it can be oversensitive around the centre position.  Make sure you are landing on-speed, on glideslope and on-AoA.  Don't engage NWS too early.  Get lots of practice, and if it is WWII tailwheel aircraft, don't stop flying them until they are tied down.

I’ve tried toe-brakes on my rudder pedals as well as the “W-“ key to exclude any differential braking that may be happening. This has been an on-going issue since day 1. I primarily use the F-16 module but it happens in all fixed wing aircraft. Try landing in 0-wind, on the centerline and press “W”. It’ll slowly start to veer off to one side and you’d have to correct.

One can easily overcorrect and start to oscillate with ever increasing deviation. This could be the result of simulation sampling rate but I can’t be sure. Also, I’d like to know how DCS simulates runway friction. I seem to remember that it has different runway states but this was many years ago.

It has always bothered me and I am a bit surprised that some of you don’t see this issue…

F-16 = AEROBRAKE. It took me a long time to get it right.

That’s not the issue and, again, this affects all fixed wing a/c.

BTW; aerobraking in the F-16 is not necessary. If the runway is short you’re better off lowering the nose and braking normally. Aerobraking is done to limit wear and tear on the tiny discs.

While there are certainly some aspects that I would like to see improvements on in the WW2 side of things, I cannot speak to modern aircraft. However, I would highly recommend setting curves both in brakes and rudder. 

DCS allows you to press the brakes excessively hard compared to IRL which leads to over controlling very easily in most aircraft. So you must tune your hardware with this in mind. 10 lbs of force to the joystick may equal >100 lbs by the pilot within DCS.  With proper curves it tends to do quite well in my opinion, but certain aircraft like the F-14 you will always need to be careful with as the ABS needs some work.

The only issue is your skill to keep the aircraft centered. It's not a train that runs on rails and it's never perfectly balanced either regarding drag and weight. If you're driving a car 200km/h you better keep your hands on the steering wheel and keep correcting. Practice, use curves for rudder if you need and you'll get it eventually.

Airplanes have very small tires in relation to the mass of the plane resulting in a small contact patch.

They skid really easy, especially when braking from ~100kn or so. It's not comparable to a car.

If you map your brakes to an axis, you can use saturation or curves to apply them slowly.
