February 11, 200323 yr I fully agree with Tero. The PW FDE is complitely different from the RR we tried yesterday. This is now very much closer to the 757 simulator I've flown (which btw. was in PW engine configuration every time I flew it). The way the RR FDE acted in the descent wasn't certainly what I had experinced in the simulator. The PW in the otherhand couldn't be closer to it. The way the ground effect takes the vertical speed off in the flare and the ground handling are magnificient. So I guess it really makes a big difference how much thrust is specified in the FDE and perhaps there really is a this large difference between the different engine types in the real world.The only thing that I still find a bit strange is the acceleration on the ground with idle power. It certainly wasn't what I had used to in the simulator. It's better now with the PW FDE than with the RR, but it's still there. But I'll ask around for this and get back to this when I'm complitely sure of how the 757s with PWs perform in the taxi.Anyway, fantastic job with the FDE! It sure makes flying 757s much more realistic than it was with the 767 FDE.Regards,[table border=0" cellspacing="0" cellpadding="0][TR][TD]http://mikael.svly.net/mikael.gif[/TD][/TR][TR][TD]fisd.fsnordic.net][/TD][/TR][/TABLE
February 11, 200323 yr I would suggest you to take a look at http://www.pmflightplanner.com The performance and fuel consumption date used by PMFP is based on the same figures Eurocontrol uses.Regards,[table border=0" cellspacing="0" cellpadding="0][TR][TD]http://mikael.svly.net/mikael.gif[/TD][/TR][TR][TD]fisd.fsnordic.net][/TD][/TR][/TABLE
February 11, 200323 yr Well I was very happy to find not only a truly stunning 757 visual model, but also a very nice flight model that works well with the PIC panel :)I took the 757 for a quick test flight from EGLF to my local airport EGMH.... and I had huge problems slowing the aircraft down on approach. One missed approach later I finally got it right ;)I then took the aircraft on a "proper" flight from PANC to KMSP. Iz has done a fantastic job with the flight model! I was very impressed by how smoothly the aircraft reacted to my control inputs. On the approach to MSP I got rid of the AP/AT and hand flew the aircraft all the way down. It's a real joy to fly, and the flare and touchdown were very smooth.Looks like the new 757 is definitely going to be in my hangar for a while yet!BTW, I used Matt Zagoren's 757 data for takeoff speeds. For Vref I just added 10 knots to whatever the 767PIC FMC was telling me; e.g. the 767 FMC was telling me Vref @ flaps 30 would be 119 knots. I just flew at 129 and the aircraft attitude seemed just about right and the landing was nice and smooth.All we need now is a fuel planner...
February 11, 200323 yr Hi Iz,I can confirm that parked at the gate, parking brake on, the aircraft continues to move forward, albeit at a snails pace...this was after a flight and some taxiing, 4.5T fuel on board. (RR engine 40,100 static thrust config file). I can not say I noticed it moving after start up, seems to be a problem standing still after a flight.I played with the ZFW for landing. With 6T fuel, the FMC numbers match the 757 charts using a 'dummy' ZFW of 216,000lbs (98.0T). In this case, the Flap 30 was 121kts in both the FMC and the charts. The aircraft flies very well by hand, I approched a windy Halifax at Vref+10 (131kts) and it was a joy to fly. Whether these 'landing' ZFW numbers will work at different Gross weights is yet to be tested.Great stuff!Rob. System specs: Dual core E6300 (1.86g X 2), 2gb RAM, nvidea7800GT, Saitek yoke, CH throttle (6 lever), Soundblaster live.Add-ons: FSX: LDS767, FSL Concorde, FT E175/195, PMDG 747X/737X, Active Sky E, some freeware airports.Human specs: Desktop simulation since FS1, beta tester (LDS, FSL), 737NG simulator tech (Threshold Aviation), r sole+.
February 11, 200323 yr Me either Iz, I sit without the parking brakes on and do not move at idle, maybe my weight though.Best Wishes,Randy J. [email protected]" A little learning is a dangerous thing"AMD XP2100 |MUNCHKIN512 DDR RAM |ECS[/b ]K7S5A MB |[b]GF364 MEG |WIN XP PRO Randy J Smith
February 11, 200323 yr No probs with me either sitting with parking brake on. I am using the DAL model so who knows?? Eric
February 12, 200323 yr Ok I was heavy so went and gave my bird only fumes to digest while testing taxi and she will not move on her own even without the parking brake set but is very responsive to throttle movement :}. I like the way the wings *shake* when applying power. Here's a shot of my new baby, Captain Bball would be proud Best Wishes,Randy J.

February 12, 200323 yr Took her for a quick spin from Chicago to Atlanta this evening.Aside from the Original American livery having some blurry textures it was enjoyable - a few things I noticed:The aircraft appeared to be UNDER powered rather than OVER POWERED.With a ZFW in the FMC of 286 and 28,000 lbs of fuel and a CI of 90 it took us 28 minutes to climb to FL330 with FLCH 230 to 10,000, FLCH 270 to 16,000, and VNAV engaged the rest of the way.Descended very nicely and was actually able to get good control of her. I was vectored in for the visual a little high so I came in a little quicker than I wanted to and as a result I crossed the threshold still doing 140, the bird was very responsive to my corrections before touching down - perhaps the rudder effectiveness needs to be turned down a hair.Taxi was ok for me, it did accelerate to about 26 at idle but it was easy to control with a little braking, also no problems after setting the brakes.Ian Elchitz CYWGIncluded a shot of her at FL330
February 12, 200323 yr "Aside from the Original American livery having some blurry textures" You know I have noticed that to, it seems to happen only on the forward area. When I zoom in and out it seems to correct this. IFDG guys, any word on a fix for this?Best Wishes,Randy J.

February 12, 200323 yr Hi Mike:I concur with your assessment using the AAL version with RR engines, I certainly wouldnt call it a "rocket" unless I tried climbing at max climb speed and max climb power, and even then I was only getting maybe 4,500-5,000fpm in the teens.Damon (AAL666)All in all though, a very nice aircraft :-)
February 12, 200323 yr Hi there - I'm not an IFDG guy, but a way to fix this is to download yourself a copy of DXTBmp from http://www.mnwright.btinternet.co.uk/index.htm (assuming you don't already have it), and then open the texture in question. Select "Prefs", and make sure "Include Mips" is NOT 'checked', then re-save the texture in the format you desire - you'll have a choice in the 'Save as type' box. I prefer "Extended 32 bit 888-8", but that will depend on your system resources. If you're only doing this to one texture, where there are three for the fuselage, for example, you'll have to make sure all texture formats match in order to avoid dissimilar appearances. If you're not sure what format they are, use Imagetool to first open the texture, and click "Image" then "Format", and it'll show you what you need to know.Maybe there's a simpler way, but this has always worked for me.Hope this helps,Mikecyul
February 12, 200323 yr Guys,The 757 is the most overpowerd western aircraft. The problem is that most aircraft in FS are unrealistically overpowered. I don't know if it's the creator's impatience to get to cruise level or what. For example, the MelJet b747/777, even though the most fantastic visual models for FS to date, are WAY overpowered, so are the stock FS planes and even the previous version of our iFDG 757 was too overpowered! Much more than this. The problem lies not in the programming of the engine settings but in drag factors that are unrealistically low.Two days ago out of Banjul, Gambia, we were almost max gross and with a warm atmosphere (only -30c SAT at FL300), it took us more than 25 minutes to climb to FL330, with a tailwind kicking in, making it even more difficult, using full climb thrust. But then again, on a short Nice flight a few days before, we were up to FL370 in 14 minutes from brake release with a light pax load. Remember these 14 minutes for my next example.Last week, we departed Tenerife 2 minutes behind an Air 2000 Airbus A321 (looks like a 757, only a bit smaller and slower). Since they had the same routing across the Atlantic as us and cruise just a tad slower, we went up to FL360 and they climbed to FL340. We outclimbed them right away, even with the 2 minute delay. I decided to check the time between us reaching FL340 and them doing so by monitoring them on TCAS. After about 8 minutes, they still didn't show on TCAS so I was wondering if there was a transponder or TCAS fault. Checked them on my weather radar and got a return. Then, finally, they showed up. They took 14 minutes longer than us to climb to FL340 and the last 700 feet took 4 minutes, which means an average of 175 feet per minute climb during the last four minutes!On the 757, we start getting impatient when the v/s drops below 1000 fpm, but these guys apparently don't mind seeing the aircraft creeping up like a snail for 4 minutes (probably longer). I knew the A321 was no match for the 757, but this actually amazed me big time.So it's a good thing I did the 757 FDE and not the A321 otherwise the whole forum server would overload with messages going "Ahhh the bird doesn't climb, what did you do with it??" :) Anyway, for those finding the rudder too effective, you can open the Aircraft.cfg file and locate the line that says "rudder_effectiveness=1.000" and tone the number down to whatever you wish (0.5 being half as effective as now). It was a bit of a compromise, because I fly 767PIC with both "yaw dampers" on, even though I have separate rudder controls. It's how it works in real life, so that's how I want to fly it. If you turn it off, it's probably overly effective, so you may want to tune it down. Same goes if you fly the 757 without the 767PIC panel. Hope that helps.I will go and try to replicate the 757 moving with idle thrust and the parking brake set.Cheers,Iz
February 12, 200323 yr Hello Iz,Thank you so much for the realistic 757FDE!! I'm really enjoy flying the PIC757~~ :-lol Since the 757 FDE you made is so accurate, I would like to know how do you feel about the PIC767 FDE? do you think it's overpowered or underpowered? and if you could share other characteristics which in your mind with us will be great~ I really love B757/767, and would like to hear some ideas from a great B757 pilot~~:-) Wish All The Best~Tommy
February 12, 200323 yr >>So it's a good thing I did the 757 FDE and not the A321 otherwise the whole forum server would overload with messages going "Ahhh the bird doesn't climb, what did you do with it??":-lol :-lol Priceless!! Eric
