Um, no. When you engage the AP it's in the basic (heading hold) mode. CSS isn't a mode, it's a function which is an important difference. (see 2.9.2.1)

Emergency brake doesn't apply during rollout/taxi
bbrz replied to DiscoVolante's topic in DCS: F/A-18C
Antiskid doesn't really work with normal brakes either in the DCS F/A-18. It doesn't decrease the landing roll and it leaves the same black tire marks on the runway. The only difference is that directional control is better with antiskid. Definitely a bug, but unfortunately not for ED. Haven't checked if there's anything in the -1, but usually emergency brakes don't have antiskid capability. -
Doesn't A-10C feel more flight capable in real life?
bbrz replied to Worrazen's topic in DCS: A-10C Warthog
I don't get it. Maybe it's a language problem. But underpowered and sluggish are two entirely different things. Whatever. -
Su-25T vibrations on the ground and seemingly weak nose gear...
bbrz replied to umkhunto's topic in Su-25 for DCS World
Have to try ASAP when I'm back home. @Zeagle. thanx for the offer, :) but I guess that after a few decades of RW flying I simply enjoy to have to whole sky for me and not having to communicate with anyone ;) -
On the other hand they can retract at high Gs and you can put the engines into ground idle in the middle of a dog fight. No fun either ;)
-
Exactly the same happens in the real F/A-18. ;) That said, given the very low thrust the engine develops at these low RPMs, the difference in landing run would be marginal and wouldn't account for a 50% increase. Again, the main problem is that full antiskid braking and sliding along with locked wheels results in the same distance being use which is a of course a plain and simple bug,

bbrz replied to Worrazen's topic in DCS: A-10C Warthog
No it's not. It's about both issues and in post 22 he wrote sluggish and underpowered. -
The minimum landing distance is achieved by performing a normal unflared landing. You don't land with 'a bit of thrust', you simply keep approach thrust, speed and vertical speed down to touchdown. As soon as you have touched down, you pull the thrustlevers to idle and apply full braking. @Preendog. Don't know where you've found this table. Why don't you simply use the performance tables from the -1?

bbrz replied to Worrazen's topic in DCS: A-10C Warthog
? That's a strange interpretation/conclusion. Because the A-10 in DCS feels underpowered, it doesn't imply that the real one is overpowered. -
Brakes on the DCS F/A-18 are definitely wrong. You need approx 50% more landing roll than the real F/A-18. The problem seems to be the wrong antiskid simulation since the DCS F/A-18 needs the same distance with antiskid and without antiskid and locked wheels. This problem has been reported quite a few times already but for some weird reason ED doesn't consider this a bug and moves such threads into the whish list ?!?!? There's no 'fake' idle. In flight the engines are at flight idle and you are not supposed to land with idle thrust. If you reduce thrust to idle immediately after touchdown the engine will be in ground idle. @Harlikwin, if you push the stick forward you will unload the mainwheels and decrease the brakes effectiveness even further.

Su-25T vibrations on the ground and seemingly weak nose gear...
bbrz replied to umkhunto's topic in Su-25 for DCS World
Again, the shaking during taxiing is exactly how a tire failure looks/feels like IRL. The link for the real video doesn't provide a usable comparison since the camera is apparently riggid attached to the canopy. Maybe as Ironhand wrote, there's a difference between SP and MP. I can't tell because I never do MP. That said, in your DCS video the shaking is also unrealistic. Even on runways with rough surfaces the bumps should occur at a much lower frequency. -
Yes, you are correct. But even with out CSS, the AP in its basic mode also reduces the bank angle to 0deg if it is less than 5deg.

missing info F-5E Turn Performance and Drag Model
bbrz replied to Viking22's topic in Bugs and Problems
Since the flaps are AoA controlled, don't they automatically retract when unloading? While speed might bleed a bit less with the flaps up in a steep turn, the turning circle will be noticable greater. -
But that's the crucial point. The angle is not 90deg, it's alway less. Another important point is that the nosewheel usually carries only 15% of the airplanes weight. If the nosewheel doesn't provide any steering input, the tiny amount of 'offset' would be way too low to cause this effect, if the nosewheel would actually be turned 90deg, which it isn't. @majapahit, why not? Weight distribution is very similar and I haven't seen any other video which demonstrates this unintenional skidding this obvious.
-
ATTH should keep the wings level (heading hold) if the roll angle is <5° when engaging this mode.
-
The only stupid thing here is your response. You have apparently no idea how easily a nosewheel can start skidding IRL and I don't know what kind of magic 'offset' should be responsible for this physically impossible turning behavior. I suggest you simple take a look at this video:
-
The point is, if you are too fast, too high steering angle, at no point does any plane IRL turn into the opposite direction of the steering input, regardless if it's skidding etc.

Su-25T vibrations on the ground and seemingly weak nose gear...

In the thread below this one ;) https://forums.eagle.ru/showthread.php?t=174009 -
I'm exlusively using land based runways and even at 0 wind the F/A-18 turns into the wrong direction with full rudder deflection if you enter the turn at a too high speed. If you e.g. taxi at 10kts and apply full right rudder with the steering in HI, she will start to turn to the left and even if you reduce the speed to below 5kts she will continue turning to the left. If you apply full rudder at e.g. 5kts you can do extremely narrow turns, into the correct direction of course.
-
Nevertheless the plane shouldn't start turning into the wrong direction. I've noticed this weird behaviour as well. This worst thing that happens IRL is that the plane continues in a straight line.

I can only image that a SOF reads the bold face items as a backup, just in case the pilot did miss any item. Not knowing any of the memory/recall items to 100% was and is an absolute no go, in military and airline ops. Flying in the military back in my time was way easier and straight forward. Reading about all the procedures etc. reminds me much more of modern airline ops!
-
No. The doors have uplocks like the gear itself.
-
There is no other way to open to gear doors from the cockpit and it's not required or standard ops for the pilot to open the gear doors when leaving the airplane. If you use the D handle, it's a good idea to install the gear pins beforehand ;) In some (much bigger) planes there's a switch/handle in the vicinity of the gear bay to open the main gear doors.

Seems the spring of AUTO BALANCE SWITCH has broken
bbrz replied to Northwind's topic in Bugs and Problems
Not sure if the switchology is fool proof IRL either. Does it work correctly when you are moving the switch to L LOW?
