Helicopter Drop out?

[leafer]

Heh... I always joke with my girlfriend about how many interesting ways there are to die in a helicopter. Just to make her nervous when I fly. I torture the shit out he poor girl.

 

But SRSLY Helos rock. try landing on a mountain top in a fixed wing. sure we can't break mach, but you can't hover.

Harrier even worse than a Helicopter

[Phantom_Mark]

I seriously hope to see a decent Harrier flight model one day :)

Do you tell her that helicopter pilots are optimistic to die of cancer?

[Focha]

Do you tell her that helicopter pilots are optimistic to die of cancer?

 

Oh man... You are a very bad person! Why you did that? Now I am :cry:.

[urze]

even worse than a Helicopter

 

There is nothing worse about a Helicopter or Harrier .

Its worse that humans still believe to be able to control everything !:music_whistling:

;)

[Zorrin]

Oh man... You are a very bad person! Why you did that? Now I am :cry:.

 

Well it's true! I've never met a heli pilot who doesn't!

[Yo-Yo]

I was flying in black shark when i saw something weird. When ever i flaired to slow down and stop my helicopter would fall out of the sky. What i want to know is why does it drop out of the sky when im level and at full colective? Does this happen to real helicopters and if so what is it?

Another case of vortex ring state here:

And an interesting read:

[Tango]

You're reasonably safe from VRS if you keep a good airspeed. 50 kph or faster will see you clear of VRS, but you've got to watch that pull-up at the bottom if you're low to the deck - the manouver could cause a blade collision from the high g manouver in combination with pulling collective.

 

If you're low to the ground and you've entered VRS, drop the collective and side-slip aggressively. This will enable you to clear VRS with minimum loss of altitude. Dropping the collective might seem counter-intuitive, but this reduces the down-wash produced by the helicopter and enables you to clear VRS quickly.

 

Best regards,

Tango.

Earlier in this thread it was noted that it would be nice if there was a way to determine wind speed and direction while flying. There is! There is a button on the PVI-800 that will give you the wind speed and direction, although I believe it is static and only shows the data as set up in the mission editor. Still, better than nothing!

[rmakowsky]

Conditions conducive to Settling with Power (Vortex Ring State)

 

Zero or near zero airspeed

High sink rate (>700 fpm)

70-100% power

 

Avoid these situations and you will not see it. If you do get into this condition...

 

1. Altitude permitting - Forward Cyclic to gain forward Airspeed) (Fly out of the Downwash)

 

2. Collective Reduce (Reduce the force of the vortex state)

 

If you don't have sufficient altitude to fly out, then the ground will eventually stop your sink rate (with bad effects of course)

[Frazer]

If you are lucky though, you will reduce the vertical spead a bit shortly before touchdown, due to the ground effect ;)

[Yo-Yo]

There is another condition to VRS - if you have high pitch (AoA) trying to decelerate too aggressive. IN this case your speed can seem not low but due to the high AoA it will be rather vertical for the rotor than horizontal. I think the second video is closer to this case.

[Vortex]

Try to not descend so fast. I think max maybe 8 or so m/s? If you do get into the vortex ring you must learn how to get out of it. Usually I try and drop the nose to get some forward momentum and add collective.

 

Never add collective while recovering from Vortex ring state. Either enter an auto, or use the cyclic to gain airspeed to escape your downwash. It doesn't matter if you go left, right, backwards or forwards.

 

I think what hitman means is the like the super technical piece of string you can find on the windscreen of a Robinson that shows you which direction the wind is coming from.

 

I found myself dumped on the ground from vortex ring after a quickstop downind...

 

No that string is to help you stay in balance, it is utterly useless to judge the wind by.

 

- As has been said, you do not want to descend at greater than 300fps below translational lift with power (read collective) applied. Kinda fun in real life while training (obvioulsy not in any other case), and BS does a good job at it, even adding the buffeting and sloppy control effects.

 

It would be nice to have a wind sock at the helipads, I always look for it out of pure instinct when overflying the field. But it's not a big deal as they state the wind during the hover check. You just have to remember where the wind is coming from just like in real life!

[d0ppler]

Yeah, I must admit I miss some kind of visual indicator of the wind direction when landing at an airbase. A wind sock can't be that hard to implement I guess.

[Vortex]

Also someone mentioned those fins at the front help judge wind direction. I highly doubt that while in a hover those things will show wind direction all the while the downwash from the blades are beating them to death. They are cool to use for balance and VSI readings while on the move though :thumbup:

[AlphaOneSix]

300fps

 

I know you mean 'fpm' but I had a nice laugh when I saw this imagining how fast you'd be dropping at 300 feet per second. ;)

 

Also, I mentioned this earlier and I'll say it again: You can use the PVI-800 to give you current wind speed and direction, there is a wind speed button along the bottom that toggles the display of wind information. A windsock would still be nice, though.

[d0ppler]

aww lol i was hoping to get a quick explanation but ok...

 

Where can i download an english manual?

 

You will find this maual (and a quick start guide) under Start -> Program Files -> Black Shark.

I wonder how Jet Thunder is going?

Vortex Ring State! hahaha.... Being mostly a fixed wing guy (Real life C172 skyhawk pilot), I've only lightly played with a few rotor sims, but never got deep enough into them (until now). So I never really heard of VRS until the first time it bit me while flying a chopper in X-Plane 9! Actually I was flying a V-22 Osprey and then a chopper and I kept dropping out of the sky and crashing. I was saying to myself WTF? So I started reading about this condition of VRS and was amazed that this was programmed into X-Plane. I had never ran into this in any other sim including FSX. So by the time I started flying this BEAUTY (blackshark) I was prepared and I'm glad that you guys have programmed what I consider the best flight dynamics I've ever flown...... That is DCS Blackshark & X-plane.

 

My two favorite sims. I can't wait for every other addition to the DCS family. I am your loyal customer for LIFE!

[Grodin]

Heh this also caught me completely unaware of such thing... Just noticed i completely lost lift, maxed prop pitch with barely any results, heh, lucky i had enough time to recover from it with some random stick/rudder imput :p

[Vortex]

I know you mean 'fpm' but I had a nice laugh when I saw this imagining how fast you'd be dropping at 300 feet per second. ;)

 

lol yeah, I don't often need to write feet per minute, so I just reverted to the old FPS not picking up on my mistake!

 

Just thinking about 300 feet per second reminds me of the old ATC story. I forget the call signs but no doubt everyone has heard the story in some shape or form. An ATC is working an area over america when cessna requests a 10 500 feet cruise, then almost straight after a flight requests FL680, the ATC responds with "If you think you can get that high then go right ahead" it was responded with "Flight ### descending from FL800 to FL680"

 

It was an SR71 :D
