Daniel Roethlisberger 0 Posted January 27, 2007 Share Posted January 27, 2007 Hy all! What am I doning wrong? If I fly with the 777 and I've reached the CRZ ALT, the nose of the aircraft is still about 4 degrees up. --> Screenshot... Link to comment Share on other sites More sharing options...
heliosair 0 Posted January 27, 2007 Share Posted January 27, 2007 Maybe you are too heavy Link to comment Share on other sites More sharing options...
pilotbenjamin 0 Posted January 27, 2007 Share Posted January 27, 2007 Yes, I guess heliosair is right! You have a lot of fuel on board, so I also think that the heavy weight is the reason for that. Link to comment Share on other sites More sharing options...
Daniel Roethlisberger 0 Posted January 27, 2007 Author Share Posted January 27, 2007 Could be, yes. I landed safely in St. Denis Gillot (FMEE). After landing the aircraft pulled to the right and I don't know why, it wasn't the wind. Link to comment Share on other sites More sharing options...
heliosair 0 Posted January 27, 2007 Share Posted January 27, 2007 Was it an autoland? Did u disengadged the Autopilot after landing if it was a full auto land? Link to comment Share on other sites More sharing options...
Daniel Roethlisberger 0 Posted January 27, 2007 Author Share Posted January 27, 2007 I did disable the autopilot. But even if I didn't, it wouldn't be logical because I was on the centerline. But when I was taxiing, he was still pulling to the right and that's why it can't be the wind and the trim was neutral. Link to comment Share on other sites More sharing options...
robdob 0 Posted January 27, 2007 Share Posted January 27, 2007 Were both engines spooling up correctly? Link to comment Share on other sites More sharing options...
pilotbenjamin 0 Posted January 27, 2007 Share Posted January 27, 2007 I have got the same problem with my 777. I think the reason for that is that the main landing gear is not 100% parallel to the centerline during touchdown. The weight of the plane pushes the plane, so that it is difficult to hold the machine straight. Link to comment Share on other sites More sharing options...
Daniel Roethlisberger 0 Posted January 28, 2007 Author Share Posted January 28, 2007 Yes, N1 was the same on both engines. @pilotbenjamin. Is there a solution for this problem? Before I took-off (FMCZ) I had no problems taxiing but after landing, I was taxiing like a fool . Link to comment Share on other sites More sharing options...
pilotbenjamin 0 Posted January 28, 2007 Share Posted January 28, 2007 I don't think that there is a solution for that, but I just have the problem when I rotate during take-off, but especially during touchdown with the main landing gear. I have no problems during taxiing. I actually don't know what could cause this problem, maybe someone else knows? Link to comment Share on other sites More sharing options...
pilotbenjamin 0 Posted January 28, 2007 Share Posted January 28, 2007 I want to add that my 777 gets unstable, especially in the case when I fly with a low weight. When I fly with a heavier weight, the problem doesn't occur as much as in the case of low weight. Link to comment Share on other sites More sharing options...
altstiff 28 Posted January 28, 2007 Share Posted January 28, 2007 Having some pitch is normal while at crz altitude. I'm pretty sure I read that in one of Mike Rays books. Link to comment Share on other sites More sharing options...
Daniel Roethlisberger 0 Posted January 30, 2007 Author Share Posted January 30, 2007 Today, i flew again to Reunion island, however, it's my favourite airport. After landing, I had the same problem again... but to the left Link to comment Share on other sites More sharing options...
João Pinto 23 Posted January 31, 2007 Share Posted January 31, 2007 Well, First of all, the pictures you post here aren't helping much because they show a situation in wich the aircraft is stable with GL and LOC captured and APP mode engaged. Then you say you disengage the AP and the airplane turns to one side. You should post pics of THAT situation. Plus, show us the EICAS with the control surfaces page. Also show the winds and FMC PERF Page. Without that information, I can say that can be caused by: a) Single Engine thrust input. FS9 and FSX allows you to pick an engine to control. You can control one of the two engines by pressing "E" then "1" or "2" selecting the engine you want to operate. To go back to dual operation you must enter "E" then choose "1" AND "2" quickly. If the turn isn't too steep could mean one side of the A/C has more fuel on that wing than the other. Make sure all pumps are or and if you get this situation activate cross feeding. c) Your joystick isn't properly calibrated. You don't feel anything wrong when you fly because the 777 is FBW and all inputs on can make on the yoke aren't directly operating the surfaces. So if a joystick is badly calibrated (some joys like the Saitek are auto-calibrated, you are required to move it to its limits once and while, if not, you might get irregular behaviour) you will only feel it AFTER the AP is disengaged to manual mode. This is particularly nasty with RUDDER input. Which I think is what happening to you. Yaw Damper is on, I'm sure... is it? d) Are you landing in the right runway? Crosswinds can be nasty. You don't show us any winds. Also, you'll need to check your instruments in that second picture. Your QNH/Altimeter is totally wrong. You're flying BELOW ground, and you must pay attention to what the Upper PFD section related to the AP is telling you. It's in FLARE and ROLLOUT modes! That's ground only situations. For the Airplane you landed already! Also, 117000 Pounds of fuel on landing???? Do you want to make a hole on the floor??? Plan your fuel properly. No A/C could ever land with that ammount of weight. The upper image is even worse! Link to comment Share on other sites More sharing options...
Daniel Roethlisberger 0 Posted January 31, 2007 Author Share Posted January 31, 2007 117'500 Pounds is ok, because I don't want to refuel before I get back . Fuel is expensive there... I'll post those screenshots. But I can except your 4 possibilities. The front-gear is really pulling to one side like I'd turn the joystick fully to one side, but he's properly calibrated, because the 777 is the only aircraft with which I have this problem. But like I already said, only after landing. Edit: Maybe a dumb question, but where can I find a fuel-planner for the 777, because I don't even know the GW and the ZFW while setting the FMC.

Daniel Roethlisberger 0 Posted January 31, 2007 Author Share Posted January 31, 2007 Ok, found a fuel-planner. But I still don't believe that it's the fuel that causes this problem. Link to comment Share on other sites More sharing options...
pilotbenjamin 0 Posted January 31, 2007 Share Posted January 31, 2007 The fuel planner actually comes with the program. For example go to "Start" - "Programs"- "Justflight"- "777 professional" and then you should find the fuel planner. Link to comment Share on other sites More sharing options...
Daniel Roethlisberger 0 Posted January 31, 2007 Author Share Posted January 31, 2007 Yes, I found it. Thank you. Link to comment Share on other sites More sharing options...
João Pinto 23 Posted February 1, 2007 Share Posted February 1, 2007 Fuel is the key! You CANNOT operate the a/c properly with such LW. Although the A/C can land with 400000+ lbs MLW, it's only intended for emergencies and it does require a longer runway. I don't know your ZFW (it seems you don't either) but I would guess you're running in the operational limits, hence the higher pitch cruise. As for the FMC programming, if you're not using it properly, man, you rather not use it at all. In FMC precision relies not only the basic TO speeds and performance, but also the Cost Index, fuel comsuption calculations and many other operational (and crucial) systems. Pilots train FMS a lot. It's the heart of every flight. If you can't handle it, you'll find all sorts of problems. I'm not being too picky, it's the truth. Find your weights in the Aircraft/Fuel And Payload menu in FS2004 and sum the two values "Empty Weight" and "Payload" to get the ZFW. DO NOT USE THE FUEL OPTION IN THIS MENU. In the main panel of the pss777 bird you'll find those small shortcut buttons. Pick the Setup button and use the "Fuel" option there to make your load. As for the planners, check your Start Menu in Windows. You'll find a Load Manager and Fuel Planner in the "Just Flight 777 Professional" folder.

Daniel Roethlisberger 0 Posted February 1, 2007 Author Share Posted February 1, 2007 Ok ok, the screenshot was only a test flight, so don't mind. I use the FMC very often and i CAN use it! Boeing better than Airbus. Anyway, I just didn't know the ZFW and the GW (resp. the fuel) for the 777 because I own it since Saturday and it's not the only aircraft I'm flying. Indeed, I know about 20 aircraft and I know them well because I fly them very often, from the Cheyenne to the Queen 747. So please don't advise me how to use an FMC! Thank you even so for your response. Link to comment Share on other sites More sharing options...
pilotbenjamin 0 Posted February 1, 2007 Share Posted February 1, 2007 Well, I think that it is a fault in the program. I don't think that the fuel is the reason for that, because I have the same problems as you and it also occurs with less fuel. Link to comment Share on other sites More sharing options...
Daniel Roethlisberger 0 Posted February 1, 2007 Author Share Posted February 1, 2007 Yes, it also occurs with less fuel, but not so bad. I tried it today with almost zero fuel on board but he still pulled a bit to the right. I just contacted the support of Just Flight, I'll tell you if i have a soultion or a patch or something like that. Link to comment Share on other sites More sharing options...

João Pinto 23 Posted February 2, 2007 Share Posted February 2, 2007 So please don't advise me how to use an FMC! Well, I'm sorry you take my reply as you did. In my life I am always learning and I enjoy when someone tells me I am doing something wrong. I didn't mean to offend you, but to help you. Anyone with flight experience would tell you the same as I did. Furthermore, do you think I actually waste my precious time coming here with such elaborate replies just because I want to offend people? Think twice, this isn't the case. Coming back to the Errors you report, I couldn't reproduce them at all, even in crosswind situations and MLW Landings close to 400000 lbs. I did read something about rudder conflicts regarding force feedback issues (not supported in most procedural add-ons). I also noticed how heavy landings can produce some undesired bouncing close to touchdown with a nose down attitude in autoland. But that's been reported even before Just Flight Release.

Daniel Roethlisberger 0 Posted February 2, 2007 Author Share Posted February 2, 2007 Sorry, I thought wrong. But I'm flying those birds since FS95. Thank you anyway for your time to help us solve this problem. Just Flight didn't answer so far. Link to comment Share on other sites More sharing options...
