Kite Posted November 18, 2011 Posted November 18, 2011 Hello . Yesterday evening we tried a combined mission on BS2 - A10 scenario . Beyond the usual strage behavior of the ka50 in trimming ( i will post a track on this matter as soon as i can ) it happened two things never happened to me... 1. First of all the PVI-800 gave me 5 km/ hour for the wind and the tower gave me 10. What can be? 2. In PVI 800 if i push only the button wind/direction shoud give me the wind in my actual position? correct? In hover it gave me 5 km/h but i cannot have a stable hover. In a "level wing hover" i was side sliding 40 km/h. ( with 5 km/h of wind it is strange ) 3. Launching the Vikhr i cannot hit target from 4 km distance. All locked , laser on and everything working. "C" on Hud from 4 km and the vikhr stops simething like 20 meters away from target. Could it be also here strong wind? Thank you for the help.

In hover it gave me 5 km/h but i cannot have a stable hover. In a "level wing hover" i was side sliding 40 km/h. ( with 5 km/h of wind it is strange ) Wind velocity is being displayed in m/s. 5 m/s equals 18 km/h and will render your Shark accelerating to the 40 km/h you mentioned within just a few seconds ("Uniform Acceleration", s.a. http://en.wikipedia.org/wiki/Acceleration#Uniform_acceleration).

"C" on Hud from 4 km and the vikhr stops simething like 20 meters away from target. Could it be also here strong wind? Could be slant angle - try and place the tracking gate towards the top of the target. In the absence of a track that's my best guess. Novice or Veteran looking for an alternative MP career?

Kite Posted November 18, 2011 Author Posted November 18, 2011 wow. 5m/sec are 32 knots about correct? I belive my problem having a stable hover is also meteo condition.... regarding slant angle .. i don't know Viper. I was in hovering 4 km away from target... the gate was in center of my target and the vikhr missed really at least of 20 meters away. I was able to hit at about 2 km distance. I will try to post a TRK as soon as i make it. thanks
MTFDarkEagle Posted November 18, 2011 Posted November 18, 2011 4k range should be easy hit for a Vikhr. If you could provide a track, we could have a rurther look. Lukas - "TIN TIN" - 9th Shrek Air Strike Squadron TIN TIN's Cockpit thread
Boberro Posted November 18, 2011 Posted November 18, 2011 The longer distance between you and target the wider laser grid is. 4 km and side flying at 40-50 km might have cause exiting missile from grid, but I don't believe at all it was reason in this case hmmm Reminder: Fighter pilots make movies.

Luigi Gorgonzola Posted November 18, 2011 Posted November 18, 2011 wow. 5m/sec are 32 knots about correct? I belive my problem having a stable hover is also meteo condition.... Roughly 9 kts. See the conversion table at Wikipedia for additional confusion: http://en.wikipedia.org/wiki/Knot_%28unit%29 DDWFTTW I don't think it can be done in a helicopter mkay - didn't know of that DDWFTTW thingy, else I'd probably chosen a different hint. (And I doubt it really applies to the phenomenon of a hovering helicopter being accelerated by the wind - but discussing this would be OT I assume?) Very interesting though, thanks for the hint :) Point is that you'll always drift in the direction the wind is blowing to if you do not compensate that drift accordingly (cyclic/rudder). And "level wing hover" does pretty much sound like a hovering attitude lacking an appropriate wind compensation. Also thought about this one: First of all the PVI-800 gave me 5 km/ hour for the wind and the tower gave me 10. What can be? Given the (brief) description of the PVI-800, I'd expect it to be loaded with "static" data by whomever and prior to machine startup while the tower might be able to use real-time data. Hence the difference.
71st_Mastiff Posted November 18, 2011 Posted November 18, 2011 I have found that fog and rain do degrade the laser and vkhr performance this BS2v. I turned off wind, also this seems to have helped with the hovering and trim issues. :joystick: "any failure you meet, is never a defeat; merely a set up for a greater come back", W Forbes.

Kite Posted November 18, 2011 Author Posted November 18, 2011 If my calculation are correct ( but my mathematics was terrible ) 5 meters x sec are 18.000 meters per hour. 18 km x 1,85 = 33,3 knots If it is correct 33 knots are a lot... i can understand my K50 throwing me around like a leaf in this condition..

It's the other way around, actually. 18 kph / 1,852 =~ 9,7 knots. Besides, I just learned on Wikipedia that 1 knot is roughly equal to 0,5 m/s, so converting m/s to knots should be pretty simple even with rusty mathematics and no calculator. :-)
Kite Posted November 18, 2011 Author Posted November 18, 2011 1 miles is 1.85 km sorry bad day and bad maths. So I don't think that 9 knots are enough to miss a vikhr . I need a track. During the week I will try same metro condition. Maybe is that what is displayed in pvi800 are ore setted info and the wind was stronger. Also teammates on a10 have difficulties in fliyng thanks
WildBillKelsoe Posted November 18, 2011 Posted November 18, 2011 show us a track AWAITING ED NEW DAMAGE MODEL IMPLEMENTATION FOR WW2 BIRDS Fat T is above, thin T is below. Long T is faster, Short T is slower. Open triangle is AWACS, closed triangle is your own sensors. Double dash is friendly, Single dash is enemy. Circle is friendly. Strobe is jammer. Strobe to dash is under 35 km. HDD is 7 times range key. Radar to 160 km, IRST to 10 km. Stay low, but never slow.

Also teammates on a10 have difficulties in fliyng thanks I tend to be a little nit-picky about things like this. So just to be sure: 1 nautical mile = 1.852 kilometers. Writing "1 mile = 1.852 km" could easily lead to confusion between miles (1.609 km) and nautical miles (1.852 km). Back on topic: I created a mission (BS 1.0.2) with 10 m/s wind and 2 m/s turbulence. I attacked some stationary ground targets from a stable hover, distance to target 7.6 km, while the wind was coming from my 3 o'clock. I scored 4 hits out of 5 shots. I then relocated so the wind came from my 12 o'clock, again from > 7 km away, scoring another 3 out of 4. So I think wind and turbulence alone shouldn't stop your missiles from hitting their targets.
