Funny moment I had in FsP

[omarza]

I downloaded a pay-load model from the downloads section for an aircraft I wanted to use. Loaded the aircraft up and the next second the nose went
skywards... i thought wat the heck as I sat there looking at the sky. went to external view and the aircraft was there sitting nose in the air, tail
on the ground looking at the sky...

Problem is fixed as I did some changes BUT just tought I wanted to share that as it really looked quite funny and one could wonder what would go
through a passengers mind if something like that really happened

How do you fix it, I have the same problem with one of my favorate plane and can not use it.

[SWAFO]

I believe this had happened once in the past. Perhaps a forum search would turn something up.

[Er!k]

My funny moment:

First flight with the demo;

Flying a B737 befor landing I wanted to stop the movie and pressed CTRL + SHFT + M instead of O

Also check your elevator trim as it could be way too high

[SWAFO]

I don't think elevator trim should have effect on an aircraft on the ground (if I'm understanding him correctly, this is where it was)

[omarza]

SWAFO... yes... It was on the ground even before the aircraft started moving.

Tato66.... I think the main cause was due to pilot having no weight and the option to load the passeneger was into the back seats instead of the front
seats... let me try to explain.... 5 passenger seats were available 2 in the back row, 2 in middle and 1 infront next to the pilot. There were 3
passengers... the seat next to the pilot was unavailable to load a passenger into... the middle row only had the facility to load 1 passeneger into
and the back row had 2 passeneger I could load into. Therefore after loading (from a weight perspective) there was nobody in the front seats, one in
the middle row and fully loaded in the back. In general this shouldnt be enough to actually lift the front wheel off the ground... and in turn I
then edited the payload editor supplied by FsP and moved the Z-Pos a bit forward as it was totally incorrect... the front seat were set on a 0
Z-Pos... middle and back rows both on a negative Z-Pos. Also in the aircraft.cfg I had the option to add some weight to the pilot but did not do
that as that werent the main cause for this severely unbalanced plane and left it as my last option and wanted to make sure the aircraft will still
fly nicely outside FsP.

How to fix it?

First, try if it flies good-mannered withOUT FSPax. If yes, proceed, if not, search for a better FDE or just stop the project.

If yes, then, in short points:

-Get Yourself an ***unaltered*** config file for Your fav aircraft (e.g. re-download and extract)
-Open "aircraft.cfg" and look for the [WEIGHT_AND_BALANCE] section.
-Compare the entries beginning with "station_load.(number)" to the ones in the FSPax payload model.
The entries in aircraft.cfg decypher as station_load.#= Weight, x,y,z. x is front-rear axis, y up-down, z port-starboard refering to the defined
aircraft center point.
While You may correctly place any passenger in a 6-seater, FSPax offers only a few possible entries while commercial jet models may have up to several
hundred "areas" where to put weight (a typical 737-300 has about 130 seats (or more), 2 cargo bays, 2pilots&2-4crew, 2 kitchens with mealcarts... now
imagine a 747 ) so You will have to calculate or at least interpolate for each FSP section e.g. for first class where its center may be
approximately and how many pax will weigh in at how many kilogramms - and check if it is correctly modeled in the FSP PM.

If You have to use a "default" FSP payload model, well, good luck. I suggest You create Your own PM then since FSP only refers to weight, but that may
be totally incorrect for some aircraft.

Airlines do in fact the same, they try to spread the pax (on a standardized pax weight) and weighed baggage/cargo throughout the aircraft so the CoG
will stay neutral the optimum. In smaller commuters, cargo jets (cargo shift) and/or private aircraft, CoG out-of-limits is a more common crash reason
and is in most cases impossible to be recovered (complete loss of control).

Okay, enough elaborating. Almost weekend, go flying!
