ryanspringer2294 Posted August 1, 2016 Share Posted August 1, 2016 Hi all, I have a problem with the POSKY 747 & 777 while taxiing. The turns are far too wide, and I end up taxiing on the grass. Does anyone know how to make the turns tighter? Any help is greatly appreciated. :) Link to comment Share on other sites More sharing options...
theyorks Posted August 1, 2016 Share Posted August 1, 2016 Left and or right independent braking as you turn. Look up the assigned keys, or even better if you can afford it, use rudder pedals. I apologise for not knowing the default brake keys, but I am not at my FS computer. Sent from my tablet thingy! Link to comment Share on other sites More sharing options...
ariking777 Posted August 1, 2016 Share Posted August 1, 2016 The Numpad asterisk (*) is for applying the brakes only on the left main gear, and the Numpad minus key (-) is for the right gear. When you apply one of those, you'll see "Differential Brakes" in the left bottom corner, instead of "Brakes". So as not to stop the plane completely when using differential braking, approach the turn at around 15-20 kts, and once your nose gear is just little beyond the centerline of the taxiway you want to turn onto, apply full left rudder (NW steering) and immediately then hold the appropriate key (asterisk for left turns, Minus key for right turns). Once you try it once or twice, you'll be able to get the feel and know when to gradually cease braking and reduce rudder deflection. http://rs258.pbsrc.com/albums/hh250/henrysb/avatar_11769.gif~c200 Link to comment Share on other sites More sharing options...
mrzippy Posted August 1, 2016 Share Posted August 1, 2016 Most POSKY/Skyspirit aircraft have secondary contact points in the aircraft.cfg. You can try using those to see if it helps. You can also check the steering angle of the nose wheel. It should be less than 90 but usually more than 45 degrees. Nose wheel is point.0 [contact_points] //0 Class //1 Longitudinal Position (feet) //2 Lateral Position (feet) //3 Vertical Position (feet) //4 Impact Damage Threshold (Feet Per Minute) //5 Brake Map (0=None, 1=Left, 2=Right) //6 Wheel Radius (feet) //7 Steer Angle (degrees) //8 Static Compression (feet) (0 if rigid) //9 Max/Static Compression Ratio //10 Damping Ratio (0=Undamped, 1=Critically Damped) //11 Extension Time (seconds) //12 Retraction Time (seconds) //13 Sound Type //14 Airspeed limit for retraction (KIAS) //15 Airspeed that gear gets damage at (KIAS) point.0 = 1.000, -20.333, 0.000, -13.833, 5181.102, 0.000, 2.042, 70.000, 0.300, 0.500, 0.880, 11.000, 11.000, 0.000, 240.000, 280.000 // Nose Gear Still thinking about a new flightsim only computer!

ryanspringer2294 Posted August 4, 2016 Author Share Posted August 4, 2016 The contact point change seems to have fixed it. But now I have a new problem. On the 747, the speed hold refuses to work properly. It will not slow down below a certain speed (which varies each time). I only have this problem while at cruise. The speed hold works fine while climbing. Any help is greatly appreciated. Link to comment Share on other sites More sharing options...

What is your altitude at cruise? Is your speed hold set to MACH rather than KIAS? Still thinking about a new flightsim only computer! Link to comment Share on other sites More sharing options...
ryanspringer2294 Posted August 4, 2016 Author Share Posted August 4, 2016 I am only at about FL290, (which is far too low for a 747) because if I go any higher, the plane oscillates up and down violently. I have the speed hold set to MACH, but sometimes the speed won't change at all, give or take just 1 knot. :( Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

il88pp Posted August 4, 2016 Share Posted August 4, 2016 First, is 'indicated airspeed' checked in Fsx-Realism Settings? (Make sure it's not at true airspeed.). Btw, i'm afraid it's one of those french 2hr downloads again. With exe. Saw a thread with the same issue 2? Months ago. [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...

Are you saying that he should substitute autopilots? Still thinking about a new flightsim only computer! Link to comment Share on other sites More sharing options...
il88pp Posted August 4, 2016 Share Posted August 4, 2016 You're right, sorry. It was the thread I was thinking of, but that issue is indeed a little different. It does however have a autopilot that doesnb't follow speed. [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...

il88pp Posted August 5, 2016 Share Posted August 5, 2016 I have that one. It's not overloaded with fuel (not overweight), just disd a short flight, and it easily climbed. First to fl260, then 300, then 380. [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
ryanspringer2294 Posted August 5, 2016 Author Share Posted August 5, 2016 I tried that, and it is still oscillating violently up and down above FL290. :( Link to comment Share on other sites More sharing options...
il88pp Posted August 5, 2016 Share Posted August 5, 2016 It flies perfectly normal here. I think it always did. I don't think I made major changes to mine, just different sounds. [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
pvarn Posted August 5, 2016 Share Posted August 5, 2016 You should NOT be using Mach for climb. You should be using IAS, switching to mach near cruise (usually as you cross Mach 0.8.) Typically about the same as other airliners, climb IAS about 280-290 knots or around 39,000 lbs/hr fuel rate total all engines. Do not fuel plane more than is necessary for the flight distance. Fueling the plane for a 8000 mile flight when you only intend to go 150 miles will cause performance problems. The oscillation is probably stall and/or over weight or fuel is not balanced for correct COG. -Pv- 2 carrot salad, 10.41 liter bucket, electric doorbell, 17 inch fan, 12X14, 85 Dbm Link to comment Share on other sites More sharing options...
ryanspringer2294 Posted August 5, 2016 Author Share Posted August 5, 2016 I have fixed the oscillation, however I still have the problem with the speed. I have set the speed to M.76, however once it gets to M.82 it will just not go any lower. :( Link to comment Share on other sites More sharing options...

I have set the speed to M.76, however once it gets to M.82 it will just not go any lower. :( OK, Download and install completed! I fly the Northwest/Delta version and I have flown this one in the past with no difficulties. I will do a full fuel load takeoff from KSFO to KDEN with a cruise altitude of ftl360 using .76 MACH at cruise. I will test the speed hold for different speeds, both higher and lower. Now the one obvious question I forgot to ask.....Ya got yer Pitot Tube heat on? This will cause some hysterical speeds if it's not! UPDATE: A nice steady climb to 36,000 feet, leveled off and set MACH to .80. It slowed from .83 to .80 after about 10 minutes. I have now set it to MACH .76 and I expect it to take a while, Tail winds! Keep in mind that at cruise altitude, speed is a good thing. Slowing needs to occur during descent! I normally switch back to KIAS for descent. 747s have powerful engines and slowing down takes some time. Still thinking about a new flightsim only computer!

mrzippy Posted August 5, 2016 Share Posted August 5, 2016 My testing is done for this 747-8i. I found that I had no problem slowing it down to .70 MACH while at cruise altitude and the speeding back up to .82 Mach. I will finish the flight into KDEN after my daily constitutional. As always, when using these high altitudes for longer distance flying, I will start my descent about 150 miles out and get down to a more reasonable altitude so ATC won't have me too high for my approach into Denver.
