Thank you for your inputs. I may have over pitched up as i thought i may need to hold more back pressure to counteract the pitch down moment (main subject of this topic) normally induced during ground effect

it's indeed the 747-8

thank you sir

i'm not asserting, I'm just asking if it's normal or not to not feel the nose down effect in 747 heavy during flare, it's a question and i'm just expecting developpers or real pilot to confirm it or not.

I guess i need to update manually, doesn't seem to work through P3D

I mostly fly A320 or B737-300 on Xplane, you usually retard at 20-30 feets, i was wondering if its the same for the 747 or you should retard between 30-40 fts ? innapropriate ? This topic is about the negative torque induced by ground effect and if the 747 should be affected or not because currently it doesn't feel at all It gets better: All of these effects are reversed when landing. In other words, when we least want a reduced indicated airspeed, a nose-down moment, or a decrease in drag and thrust, that’s what we get. It’s no wonder primary students can have trouble with their landings. source : http://www.aviationsafetymagazine.com/issues/35_10/features/Using-Ground-Effect_11069-1.html

Yes via FMC, thanks for the reply

Hi guys, When I want to board or deboard PAX, I always get a warning from GSX: OPEN door 2 even if all the doors are opened, any idea ? thanks

Hi Guys, I haven't been flying the 747v3 for months and restart flying since the -800. I messed up my flare as i Floated way too much even though it was within the LZ. But I notice that even when I released the yoke, the pitch was decreasing very very slowly. As far as i understand ground effet, it has mainly two effects : 1) as you approach closer to the ground, the vertcial speed will increase due to more lift 2) as you approach closer to the ground, the aircraft is subject to a negative ( nose down) torque. the 1) seems to be spot on but however I still reserved on 2), it seems that the decrease of pitch is due to the lost of speed after retarding the throttle. I own the 737/777/747 and all have the same issue with 2) unless i'm completely wrong. Before i was flying with the IXEG B737-300, and you can really feel the nose down effect after passing 60 feets, you needed to hold a bit more back pressureto maintain your ROD until flare. Also do you need to retard earlier ? here is a video of my landing

that's what i'm getting too i think, lmooks like the link hasn't be updated to all customer or something

well i'm redownloading right now and see if its the latest version

i dont understand, i've downladed the instazller a week ago, shouldn't it be the latest version ?

downloaded a week ago

http://imgur.com/C9cMcrM http://imgur.com/bWulvgd http://imgur.com/HBFbKd0 i've complety unistalled the B747, it doesn't appear in the PMDC OC But the downladed exe from my PMDG account is not the lastest update

i have the same issue with the B747 QotS II. I have unistalled it completly and redownload from my pmdg account, but the one i've downloaded is not the last version, how can I download the latest version ? thanks

With zoom at 1, ill can only see the pfd and ND and thats all on a 1440p monitor

Thanks for your inputs guys. Now lets go a bit harder with some crosswind:) Up to 20 lnots its okzy i managed to decrab correctly but struggling up to 20knts. Should you be fully aligned with the runway before touch down or your are allowed to decrab a bit after touch down. I noticed that when decrabing, the pitch increases slightly

okay guys, i would like some B747 pilots to rate my landing and to give me advice on how to improve my flaring i've done some base trainning with flaps 25 / 30 and 25 with crosswind. For now i only have the flaps 25 : For me i'm floating too much, i'd like some advice on how to obtain the same RoD but with less floating

12-17 fps at yssy fly tampa with 4790k@4.6GHz and gtx980ti, is that normal

Anyway its rare to see hard landing nowadays unles you have maybe like less than 50 hrs on type

Nice to have an input from a b747 pilot. I was landed with flaps 30, i thought it was the standard landing flaps lol. Whats the target pitch to flare at with flaps 25 and 30 ? Im just surprised on how small input you need to give in order to land https://youtu.be/50rIwXiS3ck Much harder landing : https://youtu.be/iBXwXLwGd9U

My pfpx uses as16 for wind data, gonna give it a try this WE, i pnly go less than 4hrs flight. I think you can update the wind data in flight

I know that a b737 is different compared to a b747 but the ground wffect physic is the same gor any aircraft. Therefore we should feel a pitching down moment on the b747. The video i posted is to only show that the ixeg had the negative putching moment and not te B747 ( maybe ?)

Ah okay, thanks for the info

I do know that the ground effect affects the planes the same way, there is in my opinion something wrong with the ground effect of the B747 making it easier to land. I only used the comparaison to show the negative torque of the ground effect which is obviously modeled in the IXEG, I'm updating another video of a greaser with the b747, i only had to make very small input to flare, i almost feel like I had to push forward the yoke to avoid floating too much. Anyway I'm just waiting for dev's answer
