Thanks a lot

So today I tried to open a support ticket for the 777 and when I went to the support page it asked for a login. I pressed login, put my username(email) and password (which I am registered with on the main website) and it said that my username or password were incorrect. I tried resetting the password but it gave me an error again, that there is no such user. So my question is: Am I doing something wrong, is it a bug, or the support website requires a new registration to submit a ticket?
Thanks in advance.

are you doing derated takeoff?  and if so 1 2 or temp based drate?  might have to recalc your drates.

 

 

Thanks Andrei.

Emirates' aircraft are not allowed to use TO-1 or TO-2 thrust, they only fill in the Flex temp and that's it. As you can see I am using D-TO 50 degrees with TO thrust but I don't think that using 100% thrust would reduce my V1 speed.

As mentioned, it calculates "balanced field" v-speeds.  This is not a runway-specific measurement.  As such, your picture isn't at all surprising to me.

To calculate runway-specific V₁, you will need to use a program like TOPCAT.

Any freeware tools would be appreciated (if available). I am low on cash, saving for the -300ER expansion Thanks.

Something must be wrong. Note that I am not complaining about my V-speeds, only about my V1
Anyway, the thing is that in my flightplan, (created using simbrief) my ramp fuel was around 127 tons if I remember correctly (in FMC it was shown around 85%) and I had selected full payload and I did not get any errors. I suppose if it couldn't take off wouldn't it have said "V-speeds not available?" or something? Also I didn't get a warning that I had passed my MTOW.

I don't exactly remember, my ZFW was 290.1 and my FOB was around 127 Tons, so my weight was around 417 tons.

So the only solution is to calculate the takeoff speeds on my own?

Hello everybody, 

I have noticed that the 777 calculates pretty high V1 speeds especially when I am really heavy, is this normal? For example, below is a picture of me taking off from KSFO RW 28R inbound OMDB (lot of fuel) and fully loaded in passengers and cargo. As you can see I am taking off with 95% thust and I had flaps 15. I would expect for my VR and V2 to be so high but what about V1? Can someone explain? Here are my V-speeds calculated by the FMC.
V1: 171
VR: 171
V2: 173
I am 100% sure I wouldn't be able to stop with that little RW left ahead of me if I aborted takeoff at let's say V1-1 knot.
Thanks in advance.
