  1. AAM states 404 can have a maximum of 47 points. I've looked at PMDG's 404 and they have a damn load of points...
  2. Trying to edit table 404 now... CL/AoA to bring down the AoA a little bit. Any way to add more nodes in AAM? Can't seem to import tables into AAM and can't edit Airs with notepad.
  3. Just wondering if it's possible to add bump and spec layers to freeware aircraft such as Posky and TDS. Without them, the aircraft looks very matte, flat and boring.
  4. Thanks Bjoern! Damn I should have jointed this forum 12 years ago... getting more help than I could ask for. I found the issue I think. Also the reason I had a lack of thrust is because I realised CFM56-7Bs are all rated at ISA+15. I adjusted the temperature settings and managed to get the correct thrust by adding about 6.5% to the 1506 chart. Creating a mach chart was difficult but in the end I thought it would be similar to the static chart but with a multiplier. First I tried 2x. This made the MTOW aircraft rocket up 41,000ft. Then I tried 1.1x and could barely make 15,000ft. I went back to 2x and observed my cruise n1, which was only 75% N1. I adjusted the multiplier so it would match a cruise n1 I wanted. Now the fully loaded aircraft cruises at 89%N1, which gives a little leeway if there are winds. I've seen images on Google of 737s cruising between 91.5% N1 and 85%N1. The climb is also pretty realistic; takeoff with 96% N1 for a 24k takeoff. At 1500ft this reduces to 92% up to 15,000ft (the autothrottle momentarily derates to 90% which is favourable) and then raises back up to 96% to cruise. Then the 300knot climb is about 2500ft/m at FL180, down to 1,000ft/m past FL350 by holding N1 at 96% at mach 0.76. Then I tried a landing. Didn't have that pitch issue anymore so I don't know what it was. Tested a 40 flaps approach, holding Vref+5 at just below 65%N1, which is correct. This was just below MLW. I'll have to test lower payloads tomorrow, but so far I'm very proud of what I've achieved in such a short time. Also things to do is adjust the fuel flow/throttle speed chart, and then make sure N1 matches N2. It matches at idle on the ground but I'll have to find some other data for higher settings.
  5. Could I ask that someone please send me the default 737-800 air file and aircraft.Cfg? I've messed up somewhere... it would seem the aircraft randomly pitches up on approach and the autopilot does nothing to stop it. Other than that the aircraft is running smoothly...
  6. Bjoern if that's correct, then all I have to do is find some info or calculations on TSFC. I have already found the TSFC at full thrust, which is 0.373. Putting this into the aircraft.cfg surprisingly gave me a very close fuel flow at idle, max static and cruise thrust (600pph,10,500pph and 2,500pph respectively), and this was before I even got into editing air files. Interestingly, I can't using the PMDG 1505 table as a reference because they haven't used TSFC at all the the CFG... infact they've even upped the fuel flow scalar, so right now I'm rather proud of having correct fuel flows. I would however like to find some real world fuel flows for the mid-range n1s. Also, I'm having issues correcting my 1506 table. The N1s I have are just calculated static but haven't been corrected. As a result, I'm missing a constant 5% thrust when test the craft. (Sea level airport, 59F, 1013/2992, no weather, wind etc. Also Bjoern, the way I explained PMDGs air files may have been a little vague. They have edited LOADs of parameters, and added loads of extra 'nodes' so that they performance is very smooth rather than jumpy.
  7. I've had ultimate traffic before and i didn't particularly like it as it quickly became out-dated. I honestly prefer freeware AI as you can add and remove packages as you please, so you can keep updating routes, airlines and their liveries. Also, on both Traffic360 and UT2, the quality of liveries are terrible because you have a team of developers rushing to get them finished, but with freeware, various people spend time on the airlines and liveries they like. However, if you persist on Payware, UT2 liveries look much better than Traffic360; Traffic360 doesn't even use the right fonts!
  8. The 430 drag table has slight changes, nothing too crazy. The 1502-1507 are a different story... so much for the nice exponential curve I've been working on... my 1506 looks like a nicely done exponential curve, while PMDG's is almost like a cubed curve. I'm guessing this may be to overcome the ground resistance at lower N1s. Also, the default 1506 only uses 2 mach indexes; 0 and 0.9. PMDG use 5 indexes and it is crazy... I'm never going that in-depth!!! Honestly though, at mach 0, PMDG 737 has like no thrust difference between 50% and 65% N1; it's bizarre... This bump reduces with mach but it's still there. Also... the fuel flow is also crazy.
  9. I'm now on to flight dynamics and editing the air files. Using the PMDG 737 as a guide. I bought it years ago but alas, the fps hurts and setting up every flight is annoying, and sometimes I just want a good fly around. I can see that there's a lot of parameters they didn't change, so I'm guessing ACES got some things right at least... I'm not going to be anywhere near as extensive as PMDG, but I would like to add a few more parameters to each file as at the moment there's too few and the parameters are very linear. Currently I'm using AircraftAirFileManager; it's good because I can see the shape of lines I edit, but I can't seem to add nodes so I'm looking for another software. What I have noticed is that idle thrust seems to be somewhat low, which may be causing me to blame ground friction. We'll have to see.
  10. Hi all, back again. In the end I bought a registration for Fsuipc so I could edit the LUA, rather than settle for the sim1.dll. I believe the default friction for concrete was 0.6 and Johann's setting was 0.3. I tested this and the difference was noticeable. I lowered it again to 0.2, and now I can throttle up to 40%, gain speed and then throttle down to 30% to maintain around 18 knots, but high enough that the aircraft won't roll forward on idle. Now I don't have to worry about inertias anymore, as I thought that was where I was going wrong!
  11. OK I've signed up to FSdeveloper. Just awaiting approval. I'll post any updates and the fix if I find it.
  12. I've been modifying the default 737-800. All is well, but even with the up-rated engines, the aircraft still requires a very high thrust (45%+ N1) to get rolling, and throttling down to just 35% N1 will make the aircraft come to a halt (at 130,000lbs, a typical weight). This is also an issue with some addon aircraft I have. I'm wondering what parameter in the aircraft.cfg or air file I can change to perhaps lighten up the ground resistance a bit, so the aircraft will roll with less throttle. Just to note I have updated the moment of inertias for pitch, roll and yaw, all of which were higher than default, but I'm unsure if lowering these right down would help at all.
  13. So I tried this and it works! All my way-points and airports are recognised! Thank you so much for you help ^_^
  14. Ah right! I'll try that, see if it fixes it.
  15. Before you say anything, I cannot provide my name in my signature until the 13th of May as I am new to both Avsim and PMDG. Today I purchased the PMDG J41, however downloading and testing different AIRACs is proving difficult, and seems the only one that remotely works on the J41 is the default AIRAC. 1405 suggests half of my waypoints planned in RouteFinder (cycle 1404) don't exist, as well as airports like ENVA Trondheim, which I have scenery for, apparently does not exist at all! I'm struggling to make realistic routes at realistic flight levels. Have I installed it incorrectly or is the new AIRAC buggy? Thanks, Shaun. Actually if anyone could be so kind to test this route on a FMS/FMC I would appreciate it. I didn't install AIRAC as an administrator... could that be the cause?
