Great to see ! Thanks.
I've never seen this in PSX....
May be you discovered here a big bug..., that this feature is not implemented.... ;)......(yet).

... spare engine carriage operation is not modeled.
:-)
A switch in the Main Equipment Centre configures the automatics for 5th pod carriage... limiting such things as Vmo

Hardy,
Ha, ha..., as I (pre)cautiously wrote: "Not yet"....
You won :D
Hessel
Is there anyone here who has ever seen this as an:
addon aircraft for our scenery generator(s) ?
José maybe ?
Hessel
Never seen it as an add-on - but I've done it for real ...;-)

When is Easter?

How much rudder trim is required?
How much aileron trim is required?
How much fuel flow correction is required?
How much drag correction is required?
What's the additional weight?
Is it always under the left wing? Is left or right side selectable?
What's the VMO then?

Hi all,
When VH-OJS operated the QFA63 flight, it was negative RVSM. Does anyone have an insight into why this would be? OJS is ordinarily RVSM approved.
James.
QuoteWhat's the additional weight?
The video mentions the weight. It should be around the same weight as an engine. The fan blades and engine hydraulic pump are removed, but then additional cowlings are added for streamlining. I understand PW's can be carried as well as RB211's.
QuoteIs it always under the left wing? Is left or right side selectable?
Only the left wing.
QuoteWhat's the VMO then?
330kts to 29,272.5', then 0.85 mach.
I don't have any values for trim, etc, but the support strut for the spare engine is only about 15' from the fuselage skin to keep yawing to a minimum.

jcomm, I just merged your new thread with this thread. It's the same subject (unless it was intended for promo).

He says "around 6 tons, just a little bit over". If I use an average of 6200 kg for
all both* engine models, I guess that would be a reasonable figure. It just affects the minimum limit on the Instructor's ZFW scale anyway, as the ZFW remains flexible.

* I just learned that GE engines
"cannot be carried as a spare, as due to their design, there is a lack of ground clearance once mounted to the wing".

Hardy,
I didn't see this thread before I posted mine.
5th pod carriage option now available in PSX 10.0.7-beta1:

Note that FMC mods re internal FF, drag, and ECON SPD logic for 5th pod is not yet implemented.

My goodness !!!
Some things are unbelievable, this is one of them.
H.
That's.... FAST!
Thx HH!
Hardy,
Could you please give some clues, where to find the model with the 5 th pod.
I cannot find it.
Hessel
You can add a fifth pod to the aircraft of your choice.
Instructor --> Situation --> Aerodynamics, then check the option on the top center of the page.
Bingo.
Thanks Will.
Hessel
I'll work up a PFPX profile addition for 5th pod probably next weekend. I have the requisite data for it, just never created it.
Note that is only supported with LRC, and no other speed schedule.

Yes, noted, among other things ...

Here some interesting reading about "our" ;) 5 th pod.
Also with some technical data.

I find the effects of the "fifth pod" very plausibly modeled, in as far as drag, and other aerodynamics effects are concerned.
Been playing with the "tick" box in "Aerodynamics" from cruise flight states. Appears beautifully modeled !
I am using Beta 7c and the 5th pod check box is greyed out. Do you have to have a specific model loaded?
Cheers,
Alex

Only RR & PW engined airframes are capable of V-Pod operations ....

See also the Beta update 10.0.7 Beta 2:
10.0.7.0007. 5th engine carriage is now disabled on GE powered aircraft.

Cool, thank you for the info.

Doug,
Do you have a link from where I can download your PFPX profile?
Have you created an ER profile by any chance?
Thank you in advance,
Mariano
-ER data simply isnt available. I have asked my sources ad nauseum. Noone has the DAT file needed. But, I am keeping watch...
I didnt get a chance last weekend - I am going to hope that I can this weekend. I create the raw tables, then someone I know will have to add it to the user performance data file.
The tool I use requires a lot of modifications in the input file to correctly model the drag polars, and there are several corrections required, so it isnt something that I should hand out...
Soon
(The last comment above was posted 3 years ago.)
Here's another (cosmetical) question:
As we know, when the spare engine carriage mode is active, the FMC IDENT page indicates "ACTIVE" in line 5R.
"DRAG/FF" is at 3L.
Now the NG FMC's IDENT page has the "DRAG/FF" at 5R.
Does that mean the NG FMC has the spare engine stuff at 3L?
Does anybody know?
I think for the 744 NG FMC they carried over some stuff from the 777 FMC. But in this case they ignored the spare engine option. The 777 cannot do this, right?
Regards,
|-|ardy

I'll put $10 USD right down now & say none of the 777 variants can ;)
Not a chance...
