USA	Re: FMC (incl LNAV, VNAV) Reply #122 - Jul 27^th, 2012, 3:17pm I'm having a problem with my decent, the throttles go to full instead of idle during vnav decent and I have to manually control the throttles to slow the thing down, then it seems like my speed brakes are useless. Is anyone else experiencing this?

They do for me on a long haul flight. But not much. On a 6500nm trip, there is only one Step Climb. Sad

Which indicates that something is wrong there. I made a 7.5 hr flight, and the OPT was FL301 and MAX FL344 the whole flight. I had the right weights and everthing too.

_______

ALSO ANOTHER ISSUE IS THAT THE IRS INSTEAD OF HAVING THE BOXES FOR ALIGNMENT, HAS 00000.000.000. It would be better to set it to the boxes for our input later.

This might have something to do with the fact that the 777 does not have its own FDE yet. In the 737, I think it was v0.8 or v0.9 before we saw got that.

I just press DELETE to remove it and then the boxes can be seen. But this problem could be because the FMC\CDU is not complete yet, which might also go on to affect the Step Climbs as well.

Not sure if i have missed these being reported already but:

Manually inputting Place Bearing Distance way point doesn't seem to work (Not in database error).

And Cross Above XXXX and below ZZZZ doesn't result in the correct restriction. It results in Cross Above XXXX and below XXXX.

for example: 2500A3500B became 2500A2500B when in-putted to the FMC.

Thanks,

Dunc

Great job on the saving and loading of flights--systems load nearly perfectly. However, I'm noticing that sometimes, after loading a saved flight, LNAV won't work.

Edited:

Actually, what's happening is, when the aircraft is off course, it turns back on course, but when it reaches the correct route again, it turns back the way it came about 20°, and maintains that new course.

But only in the 2D version of the fmc.

As well,

I have a lot of problems with the FMC initial position set coordinates ! When I load the aircraft my initial position is completly set to 00000... and I can't change it, doesn't matter if I'd start cold and dark or engines on. Right now I'm not able to do a flight because of that.

Best regards,

yes sorry forgot to mention its only in the 2d FMC, on the 0's in the FMC you should be able to clear them out with the CLR or DEL button, I was able to but dont have the 0's anymore in .7

Right now there is no T/D on the LEGS page but you can see your T/D on the Programm and VNAV page as well Wink

@Eric
Figured it out with the 0000.. As you mentioned I just deleted them.
Except of the weird presentation of the route on the ND .7 is a very good update.
