Control panel on the FO’s side inoperative

Recommended Posts

Hi,

 

I am working through Tutorial 1.5 (yet again!) and have got to Page #38, with more success than ever before.

But now I have encountered a serious problem. Here's where I am at:-

 

Page 38:-

- Remove CHOCKS, this disconnects AIR and GPU. (APU is running)
- Run the BEFORE START checklist. But I cannot change anything on the ECL, because the control panel on the FO’s side of the glareshield has become inoperable - so have all the knobs and buttons to the right of it...

 

Nothing I have tried will fix it. So it's stuck at FUEL. I've tried closing P3D v.3.4.18 after  saving the 'Scenario' and then reloading P3D and then that Scenario again, but the two panels are still frozen.

 

If I close P3D and reload it and select the 777 in the same location (Dulles KIAD Gate C2), everything works perfectly. But, of course, I've lost where I had got to in the Tutorial! :sad:

 

Any ideas as to why this is happening? The affected instruments were working OK until they suddenly failed. Better still, has anyone met this problem before and found a solution?

Sounds like your APU is not picking up the electrical load when you yank the ground power.  Monitor the electrical synoptic to see what is happening..

Thanks Dan, for your suggestion, but I can't get the synoptic to change from FUEL to ELECTRIC because it's not responding!

In any case, as it happens, I've just been presented with a VAS error and have had to close P3D. I'll try reloading the saved scenario and see if restoring Ground Power will fix it.

Well, That didn't work.

 

If it's any help, Fault Messages are showing:-

 

ENGINE SHUTDOWN

INSUFFICIENT FUEL

FMC MESSAGE

DISPLAY SELECT PANEL

EFIS CONTROL PANEL R

TCAS OFF

 

Is any of these relevant to my problem?

Look on your CDU, press Menu. Make sure both EFIS CTL and DSP CTL are OFF. When on, your are controlling displays from the CDU and this isn't what you want when you are just learning the basics.

Did you manually select at least one APU generator "on" BEFORE disconnecting ground power? The 747 is not like an Airbus, (where the APU Gen automatically picks up the load when external power is disconnected). The APU may be running, but unless you select an APU generator, you'll lose most of your electrical power as soon as ground power is off line.

 

As long as your bus ties are all working, one APU gen can power the whole aircraft - but to be absolutely safe, you can bring both APU generators online before pulling the ground power.

 

It's also probably best to manually dismiss the ground power connection and air conditioning cart using the FMS menu before removing chocks.

EFIS CTL is OFF, but there is no entry for DSP CTL on the MENU screen.

Hi Jim,

 

It is the 777 forum and the OP afaik is also talking about the 777. A little too focussed on the brand new 747?  :Tounge:

Jim,

The 747 is not like an Airbus, (where the APU Gen automatically picks up the load when external power is disconnected). The APU may be running, but unless you select an APU generator, you'll lose most of your electrical power as soon as ground power is off line.

I kept a record of what exactly I did as I worked through Tutorial 1.5 and I see that I did NOT select the APU before disconnecting Ground Power! This was because I was concerned that UPLIFT FUEL up was losing ground to the APU's thirst for fuel, so I turned it off. As Ground Power was already disconnected, I saw that ALL the FO's  panel displays had blacked out so immediately re-established Ground Power, which caused the PFD and ND to turn on. Obviously, in hind sight, this was what caused the two panels on the FO's side to lose their functions.

 

BTW, you say '747' and talk about 'at least one APU generator'. Only one APU generator is shown on the 777's Overhead Lower Panel... Is there another one that I haven't found?

 

It was my mistake not to have connected the Ground Power before starting the APU and its generator. Is there some way I can now restore the function of the two panels that have gone off-line?


To make it quite clear which are the non-functioning panels: They are the two at the extreme right-hand end of the glare shield, above the FO's ND & PFD. One includes the selection buttons for the ECL display and the other the Barometer, Minimums and Range knobs, etc.

Hi,

To make it clear, you are talking of the DSP (Display Select Panel) and the FO's EFIS panel, right?

I'm trying to find what could be the cause. What panel state are you loading the 777 with?

My apologies - I have been so buried in the new 747, I did not notice that this was a 777 question! Indeed, the systems are quite different, and I believe the 777 APU should automatically connect its generator when ground power is disconnected.

Yes, the DSP is apparently the correct name for the panel containing the selection buttons for the ECL display, and the FO's EFIS panel for the other one.

 

But I was unable to find (by doing a Search in them) mention of these names in either the Introduction or the two Tutorials hence my long-winded descriptions!

 

The Panel State was originally the Default one and then I saved the Scenario at the point where I ran into this problem so the State is now named 'PMDG B777-200 at Dulles KIAD 2.fxml.sav'. I have since used a 777 CLDDRK.sav state for the next time I start with Tutorial 1.5.

The FCOMv2 is the one document for everything related to the aircraft systems.

 

Have you tried loading again do everything from the default panel state?

I must admit not having even glanced at the two FCOMs. It seemed a bit like overkill and FCOMv2 has over 1200 pages! However I'll now bear them in mind if I can't find what I want elsewhere.

 

As there seems no way to simply correct the problem I have, I guess I've no alternative but to start Tutorial 1.5 again from the beginning with the Cold&Dark state, as mentioned in that Tutorial, Page 9, 'Arriving at the Hangar'.

 

Thank you everybody for your invaluable input on this subject. If anyone happens to come up with a way to re-energize the DSP and FO's EFIS, please let me know. :smile:

Just  after  watching  airline2sim  videos  on the  777   this  was  mentioned  about  the  2  panels  that  your  talking  about ,   think  thire is  a switch or  something  in the  cdu  or  some thing  that  turns  these  panels  to  inoperative hopefully  i can find  it  or  hopefully  some  else  can who has  watched  it   can  come  up  or  maybe Ben  from airline2  sim  can  help.  Hopefully  ben will help   other  wise  going  to be  a long  search  going thru the  videos  again:)

 

 

Ok  found  the info  hopefully  this  will fix  your  issues

 

in your  cdu     make  sure the efis ctl   and  dsp ctl  are set  to off   this  is  found  on the first  page  where  your  got  fmc   and  sat  on the left  hand  side  of the cdu  and  the efis  and  dsp  on the right hand  side

 

 

turn  these  to  on  than  your  able  to  by pass the  control panel  by  using  the  cdu ,   doesnt  explain why  the  control panel  doesnt  work  though,     it  was mentioned  in the video  the 777  captain  myron has  said  he  only  saw  the panel  failed  once  in his career
