Display problem

[ivar hestnes]

Help please

Yesterday I had a flight with all new PM updates installed and latest Nav-data. No problems at all during the flight.

But today it is not that good. I cant get the displays working properly.

Have never seen the pfd/nd like this before in PM. Same thing on both sides.

Any one have a idea of what could be wrong? ( I am not an aircraft genious to have that said).

Ivar,

I think the CDU doesn't know where it is, ie. the position airport/co-ordinates
aren't set. Has happened to me a few times...it was a net dir communication problem...

Hi Ivar,

If you loaded the new PM Systems & enabled the aft overhead, you have to turn the IRS on. That will solve that problem as I found out the hard way myself after wasting a couple of hours

Nice one Mau,

The moment you enter the aircraft (airport) position in the CDU the display turns normal.
This is a standard feature of the NG telling you that the airplane does not know where he is.
Was in all previous builds.

Yes it was Jack, but with the new PM Systems release, you have to turn the IRS to the Align position, otherwise the ND still shows MAP even if the CDU shows the current aircraft position.

Wow...great
Who said somewhere else that the new builds were just a name change!!!
( I do not use PM Sys and will have a hard time replicating that one with my circuits logic !)
Thanks for the info Mau.

I had the same problem today as reported by Ivar!
After several hours of trouble shooting I checked this thread got the right hint!
Thanks guys, you saved my day!

Hi

I thought it is not needed to describe the normal procedure because you would use normal checklists.
In any case bothe is needed
- position setting in CDU
- allign setting on AFT for one or both IRS selectors
If you select only one IRS selector to allign you need to check that the IRS source is selected to the correct IRS selector!

Hi Thomas,

A bit of description would have been nice since very few of us are airline pilots familiar with all procedures, especially IRS issues which, up to now, was never included in PM Systems. But you are right, the fault is at least partly ours

Having said that, I have now encountered a new problem which I'm sure is not included in normal checklists. Here is what is happening to me now:

I start FSX on main PC.

If I start PM systems cold & dark without Aft overhead, all is normal. PFDs/NDs turn off until battery power is turned on.

If I start PM systems cold & dark wit Aft Overhead, as soon as the PFD/ND etc go dark, the engines spool up immediately, the plane all of a sudden tries to take off, and I hear all kinds of warning sounds and even gear coming up.

Do you have any explanation for this? It almost seems that FSX is trying to re-position the plane wherever the IRS setting is pointing to, which of course does not make sense. I'm still trying to get more info about this and to find a workaround, but in the meantime, am I missing something else very basic here?

Thanks,
Maurice
