Keep looking, there are studies out there about the effects of downwash. Because manufacturers need to know the dangers that can destroy their helicopter. I'm sure you will find that by design the amount of degrees of nose up is very marginal and not noticeable to the pilot. There are so many aerodynamic forces acting on a helicopter that is noticeable that pilots are taught about it, such as dissymmetry of lift, transverse flow effect, blowback (flapback) and others. Again this is off topic from my original post and need to be on its own thread. And if you seen the video I posted, I'm demonstrating the collective's effect on helicopter pitch in forward flight that is extremely noticeable. So pronounced that I have hands off my joystick control during the flight.

It seems that most of the replies have not been about the root of the problem that I see and would like to be fixed. And that is that in DCS the UH-1H can pull out of a nose dive using only the collective with no input from the cyclic. Which in the real world, is totally impossible. If you break your cyclic in the real thing in a dive, pray that your life insurance is paid up so your family will be taken care of. As it is now, flying the DCS huey has 2 controls that will influence the helicopter's attitude which are the cyclic and the collective. The collective being the incorrect input device to control helicopter attitude needs to be fixed. I have a feeling that because the collective is modeled incorrectly, it may also be causing some of the mast bumping problems that a lot of players are complaining about.

First, the horizontal stabilizer surface area is small when you compare it to diameter of the main rotor disc. Downwash will flow over and around it just as it flows down and around the forward deck and along the nose. Most of my career was in Bell helicopters. When you preform a maximum performance takeoff from a hover, you don't have to push forward cyclic to maintain your position in the climb because again the horizontal stabilizer surface area is too small to cause the helicopter to pitch nose up. when you look at eh Uh-60 horizontal tail, it is huge. I would imagine it is angled down to prevent the helicopter from pitching because of downwash. But I never read the RFM on it, so idk.

Of all the helicopters I've flown, I never experienced a downward force on my horizontal stabilizer that made me worry about raising my collective was going to cause my tail boom to possibly hit the ground when I was near aft cg limits. Also, none of the RFMs or recurrent classes I attended ever mentioned anything about it.

Hey Wrcknbckr, if ED implemented that into the huey's flight model they would be wrong. The helicopter is very sensitive when it comes to loading of passengers and cargo because the cg moves mostly from aft to front during the flight as it burns off fuel. A helicopter that is full of fuel and had a fully loaded baggage compartment along with any passengers in the back seats will put the cg near its aft limits. If downwash had that much influence on pushing the horizontal stabilizer down like you say, that will surely push the cg even farther aft putting the helicopter out of control because the pilot will not have enough forward cyclic to stop the helicopter as to begins to move backwards. Believe me, the downwash has very very little influence pushing the tail boom down in a hover. Otherwise the RFM would warn pilots about the risk of rotor downwash forcing the cg further aft in a hover.

Putting the collective in a fixed position defeats the problem. What I did was just let go of the flight stick (Cyclic) after getting airborne and used the collective to raise and lower the nose while using the tail rotor pedals to control heading. As you have seen, raising the collective puts the helicopter into a very nose high attitude that I was able to perform hammerhead turns. Once at the top, I lowered the nose with the collective and pushed full right pedal making the turn facing down. Before crashing into the ground, I once again raised the collective to bring the nose up to parallel the ground. This is not the correct function of the collective.

LuseKofte , don't misunderstand when I say "Pitch," that I'm referring to the pitch of the rotor blade, because I'm not. I'm talking about helicopter attitude, nose up and nose down. The cyclic inputs influences the attitude of the helicopter in flight and autorotation. The Huey in DCS, have both the collective and the cyclic controlling the helicopter's attitude. Get that fixed and the Huey will fly like the real thing.

Hey Calabrone, I watched that video. What he is talking about is totally unrelated to what I was saying about the collective having a profound effect on the helicopter's pitch. The collective, in no way has that kind of influence on the vertical pitch of the helicopter irl. Flying the DCS huey is manageable the way it now. but believe me it is a constant fight when making assertive collective inputs, like having to enter an autorotation at high speeds. Most of the time the huey ends up like a lawn dart. I demonstrate a 180 deg auto in another video, but the cyclic was trimmed for the maneuver and I was prepared for the extreme nose down attitude that was going to occur when I bottomed the collective.

Many people in DCS say how the UH-1H is the closest sim to the real helicopter. The Huey is a module I regularly use and enjoy. With the recent release of the reworked F-5, the UH-1H also needs a rework. The one thing that bugs me the most is how the collective has a major influence on the huey's pitch in relation to the fuselage. How the collective works in real helicopters is that it controls the increase of all the main rotor blades pitch and allows the helicopter to climb or descent vertically. It does not control the pitch of the fuselage. The cyclic controls the fuselage pitch through forward, aft and side to side movement. In DSC, the player should only need to use collective inputs to increase or decrease height above the ground in a hover or in flight while the cyclic inputs will control the helicopter's pitch and roll. I made a 3:39 video flying around Tbilisi using only the collective and tail rotor inputs. For takeoff and landing is the only time cyclic inputs are used. https://youtu.be/Xq4ZSvcwm14

The helicopter downwash needs to match the color of the terrain it is flying or hovering over. Tho, the downwash gives the helicopter some nice visuals, it is also a curse when flying over green vegetation making the helicopter easy to spot. Also, when the collective is down, there should be near 0 downwash visuals since the blades are at flat pitch. The Pic on the top is at flat pitch and in a hover on the bottom.

I hope the Ch-47 is given the same amount of survivability as the Mi-24 and Mi-8. One Hellfire missile can take out any tank on the battlefield, but a Russian helicopter needs 2 or 3 to bring them down. I've collided with a Mi-8 in a harrier and exploded, but the Mi-8 flew away unscratched.

Ok, I recorded 2 flights. The first flight is with the Afterburner Gate box checked and the second flight is with the AB Gate box unchecked. Starting form 1000ft and setting a climb to 35,000ft. Iceman will nose up at 25deg then go 30deg as the air speed drops on the first flight. But on the second flight, Iceman maintains 25deg through the climb. No voice.

I think you are confused about what I wrote about. It does not matter what the altimeter is set to, leveling off at an indicated 34,500ft is not 35,000ft. What should happen is Iceman should level off at 35,000ft as indicated on the instrument and the F10 map should show an altitude that is standard for all aircraft because they might have a different altimeter setting than I. When at a low alt and 250kts, if I command Iceman to climb to 35,000ft, it will try to climb at 30deg nose high without afterburner and stalls the plane. Again like I wrote, Iceman will not engage afterburner in a climb or even in level flight when the "Enable Afterburner Gate" box is checked. Since no one has reported this before, I'm guessing that I'm the only one with this problem.

This has been a problem for a long time and is not new. I just chose not to change speed or altitude when in the RIO seat to get around the problem. When the "Enable Afterburner Gate" is checked, Iceman (RIP Val Kilmer) can't go into afterburner and will stall the plane if asked to climb to a higher altitude or to maintain an orbit. Another thing I noticed is that if I command Iceman to climb to a "Set Angels Absolute" like 30,000ft, Iceman will fly 500ft below the target alt as indicated on the altimeter, but on the map view the altitude is correct.

Yeah, I get the same thing all the time. I'm close enough to the target that I have to break off and evade gun fire because George will not fire the weapon on a locked target. On one of my earlier post I mentioned that George had trouble tracking targets and was missing hellfire shots all the time if I was not holding a rock steady hover. Not only that but he has trouble leading targets with the gun while flying an orbit. I posted that a while back. But ED replies with No track file included like they have never experienced problems with George. Parents are always protective of their little monsters.

Heatblur created a great product with the F-14 but they messed up with Jester, the skittish RIO. I'm sure BIO and Mooch did not lose their <profanity> in the back seat or antagonize their pilot the way Jester does. Sometimes I head for the ground to make Jester punch out to get rid of him. George is just fine the way he way he is. Only he does need to scan ahead and callout targets.

I get the TADS crash as well and its not just isolated to cold starts but Hot starts too. One time during a cold start on the The COOP 80s server, DCS crashed during a cold start. I activated the TADS before the camera was ready to display an image on the right screen. As soon as the camera was ready to show an image on the display the game crashed. I don't remember if the FCR was loaded. The game just crashed again. 1.The COOP 80s server 2.FCR loaded 3.Hot start 4.Game crash activating the TADS from Pilot seat. I have also had a game crash from he CP/G seat when I activated the TADS on the center display.

It's been 2 years now and still waiting for George to have the ability to call out targets or to be given a ROE free to fire command. There is a Wingman/Flight menu where I can give an order to attack armor or air defences and more with all the jets in the game. For now, Al George is sitting in the front reading magazines and eating potato chips waiting for me to put spot targets for him. I'm sure I'll make another post like this again in 1 years time.

Several day after this post , I had George target a taxing Mig, 4 Hellfire missiles later and I give up change to another target. Oh I forgot to mention that it was with the Hellfire K's and each time the missiles hit well past the Mig.

I too am still waiting for a fix to Iceman not going into AB because I have the AB Gate checked. It is now August 2023.

What do you need a track file for? I gave the coordinates where to look. Here it is again if you missed it in my post, (abeam parking spot 65, N13 34 37/ E144 55 37).

Referring to WarthogOs tacview: I thought it was odd that the second AIM54 fired was the lowest, almost 10,000ft lower than the highest missile, and had the lowest Mechanical Energy and was hitting the same speed as the other three. Maybe at that altitude there is no friction.

Taxing on A to B (abeam parking spot 65, N13 34 37/ E144 55 37) the ground is so rippled that it damaged the landing gear and I was forced to either repair it or get a new. I seen that others have complained about the unevenness of the surface on this map, so I doubt that this will be addressed. "It was a free map, so why are you bitching!"

Unless you maintain a solid hover with no vertical or horizontal movement, George can not hit his targets. That AI has wasted so many missiles, that sometimes I had to resort to jumping into the front and track the targets myself. Even when flying straight towards the a target he will miss if there is a slight climb or descent. George is just too with the sensor to maintain a track on target. I expect him to miss when I'm having trouble maintaining a hover, but not when the movements are smooth and subtle. Send George back to weapons training school.
