A320-family development

[Devansh_NoBlue]

Thanks for the responses. So, seems like the problem is maybe I don't have the 3d branch. How can I check that? And if it is not there, how can I get it? Does 3d branch mean i have to download a320 from github rather than using the default fg browser?

Go to https://github.com/legoboyvdlp/A320-family and change the branch to 3D using the 'change branches/tags' pulldown menu
( going directly to https://github.com/legoboyvdlp/A320-family/tree/3D might also work)

Then press green 'Code' pulldown and select 'download ZIP'.

(Alternatively, if you know how to use git, clone the whole repo and checkout to the 3D branch on your local copy)

THANK YOU SO MUCH GUYS.
I was an Idiot. Got the 3d branch a320.
Thanks again!

Devansh_NoBlue :
I recorded short video with loaded A320 take off from Paro. I used SimBrief integration, V - speeds are calculated with FSL A320 Perf Request in MCDU. I entered calculated speeds into A320family MCDU and safely took off.

Lego :
At 10:20 I retracted flaps to clean config, the target speed was 205 KIAS, but the plane accelerated. 12:36 I activated AP with speed and roll in Managed mode and open climb. As result, the plane started to decelerate to 205 KIAS.

Advanced weather in Manual METAR mode based on real VQPR METAR from 0755Z for same condition in P3D (used for V-speeds calculations) and FGFS, A320family model 2527-A5

Thanks V12

Great and helpful video. Actually, I was using A320-dev so far. I just downloaded the A320-3D. I am amazed by it's realism. Congratulations to the develpers.

Regards,
Devansh.

Branch 3D has bug in the managed speed mode. It is visible in my video - the plane accelerated till I activatd AP, then decelerated to the target speed 205 KIAS. So I do not recomend use 3D branch now. Branch DEV is OK.

lego :
Problem with managed speed is only with active AP and THR CLB mode.

It's not that it decelerated, it's just that the managed speed command never increased, I am not really sure why. I just now was able to reproduce it, and will check it out. There's also the bug on rotation for some reason that needs looking at.

Notice how the flight director bar was commanding a pitch up - that was because the FMGC wanted you to reduce your speed to 205, as the command didn't increase.

Thanks for the compliments @Devansh, the whole team appreciates it!

Kind Regards,
Josh

@V12. I believe I've found the issue.
Implementing a fix now.

Kind Regards,
Josh

[Octal450]

@V12, @Others
Fixed.
As long as there is no active speed restriction, it will accelerate properly now.


I will be looking into the flickering managed speed on takeoff next.

Kind Regards,
Josh

PS: Sorry for inactivity lately. Been quite busy.

Thank You.

Yessir,

V12 Good afternoon.

I have seen the Video 19/September, I follow your tutorial.

When I activate the asterisk to find the path in simbrief it says ( not found ) ????? where is the mistake.

miguel : thank you

[V12]

Octal450 :
I performed short test flight from Paro to Lhasa, now it is working perfectly.
Again thank You.

miguel :
Will check and report.

EDIT - miguel :
Are You familiar with Simbrief workflow ? If not, here is tutorial (not mine) :

Did You followed instructions and enter Your username into Simbrief API window ?



You can use INIT REQUEST only without running engines. If You start engines, Simbrief is not allowed. And one more reason for Not found error - Your flightplan has depart, destination or divert destination that not exists in FGFS. For example, Navigraph has not for Thoise ICAO code VI57, but VITE, so flightplan VNKT -> VITE in Simbrief probably will not work in FGFS. I must test this case.

EDIT 2 :
Hmm, when Simbrief flightplan contains airport that doesn't exists in FGFS, error message is other - Simbrief download failed. I do not know where is Your problem. I hope, lego, Octal450 or merspieler will explain.

Hey Everyone,

Found a really small issue but though significant for trim calculation.



The Centre of Gravity being shown here is a negative value. This was not in the dev branch. Does this mean it is a forward CG? If it is so, how can we use it for calculation?

Thanks and Regards,
Devansh.
