Hello folks
Using the Thrustmaster Airbus throttle, stick and Rudder pedals. Before take-off, the flaps are set to 1+F. Autobrake set to maximum and Ground Spoilers armed. During climb-out after gear is retracted, at the appropriate speed it’s time to retract the flaps. Looking over the wing you can see the flap and slat retracting.
Question 1)Setting the FMGC initiate, flap setting has [1]followed BY / [Ths]. Obviously I enter “1” but I don’t know what to enter in the next bracket. I assume that is for “+F” but it won’t accept that entry so I leave it empty. So my question is, what do I enter in that bracket?
Question 2) How do I select 1+F when initially setting up for approach? The reason I ask is if I extend 1 notch of flaps, only the slat extends but not any flap. All I get when extending 1st notch is the front slat. Then one more notch gives me flaps 2, followed by flaps 3, then full.
Any Airbus pilots here please chime in. I’m feeling a bit ignorant here as I’ve been mainly a Boeing man until I hopped into the FBW A320 which I happen to love flying.
PS - I’m using the latest FBW development release, not the experimental or stable (version 7 to memory) because SU6 doesn’t support the stable version yet.
Hi,
You just need to add a 1 for Flaps Setting 1. THS is an optional Setting which set the trim to a „Standard“ Setting, doesn’t matter where the CG is. So it’s a nice feature for the Pilot, because IRL they have the same movement at the Stick for rotate, doesn’t matter where the weight and the CG is and most important, it doesn’t matter if it is a 319/320/321.
Thats my understanding of that function, IRL Airbus Pilots, go ahead to confirm or kick my ■■■ when I’m wrong.
Setting Flaps 1 is only going to extend the Slats. That’s correct. Flaps 2 is going to extend the flaps too.
At approach, you switching to the Flaps detents one by one until Full Flaps.
You will find the target speeds at the Perf Page when you set your MCDU correctly.
Is there really a difference? Ok, never realized that. Shame on me.
I’m not quite sure if it makes a huge difference. Yes, the Pilot will „feel“ a difference, but I guess I read somewhere it’s not really necessary to enter a value. Maybe it is a company procedure.
So I found this one for the moment, but I know I read some more…. https://www.airliners.net/forum/viewtopic.php?t=733873
As I understood this correct, you need to have this calculated by a separate system, so named a Dispatch System. Will that be included in Simbrief?? Going to check this out soon. (No, the entry is missing in Simbrief)
It won’t be calculate by the FMS. So, the entry its just a reminder during your takeoff config check. Takeoff checklist, all green no blue.
Hm…it‘s strange. I guess I have to get a IRL manual of an A320 for sure. I never broke my head about the entry, because it never made a difference.
Of course it makes a huge difference. A mistrimmed stabilizer can cause an premature rotation and on the other hand severely delay the rotation, if not prevent it.
No formula. The CG/trim table is printed on the QRH.
Maybe there’s a misunderstanding. The THS setting in the MCDU doesn’t make any difference,
but the actual stab trim setting does.
Ok, we get closer. Maybe that confused me. trim setting is important but not the THS Setting.
But, the Airbus set trim by itself when all Data are set?!
Another procedure I missed until now. Maybe I should start to work with checklists and not free nose
So it always matters where the CG is, in any aircraft. Also the flap/THS setting in blue on the MCDU, in the real airplane, is totally optional. the MCDU doesn’t use that data at all. However, as simulated in MSFS, you need to enter the flap setting in order to get the v-speeds to calculate.
The Trimmable Horizontal Stabilizer setting is completely dependent on the CG. With your CG, you would either reference a handy chart or simply look at the CG/trim scale next to the thrust levers to determine what your TO trim needs to be. You would then dial that in using your trim control and confirm on the lower ECAM FCTL page.
THS is just the reminder as I read in the post I linked up.
Ok, takeoff trim will not be set automatically by the FMS.
I never took notice of that….well if there would be a Problem during takeoff, I would take notice of it anyway.
A pilot I used to fly with in the USNavy just transitioned to the A350. He was a MadDog Captain for Delta. I just shot him an email asking him to elaborate on this. I’m pretty sure that THS is an entry for the A350 as well.
When he replies, I’ll post what he says here. It could be a while as he’s doing long hauls from KDTW to Shanghai and back 3 days a week, but he always replies…
