Thanks! I found myself going too slow for my weight which resulted in a struggle for AP to hold my heading on final.

Flaps 1+F, 2, and 3 are all settings for Takeoff. Choosing the middle of those 3 settings because now folks can flop to either side and take more or less flap. š

Said this on a different topic but once again, thank you very much for this!

Personally less than 35% load, I use 1+F rotate at 140knots
MTOW take off will use flaps 2

Since I think this is the right topic to ask. What VS have you found works to slow the airplane down to cross 250. I was able to do 1300 with spoilers, just curious what you found works.
Takeoff performance on the A350 is phenomenal!
Last nights takeoff to ICN:
KDTW
Runway 22L (12,000 by 200)
Winds 230@11
CONF 1+F
FLEX
Full length
279,994KG (6kg under MTOW)
I had a VR speed of only 157 (157, 157, 159)
And I rotated by the 9L intersection, about 5800ft down the runway.
That huge wing is incredible, that thing loves to fly!

Anything less that 1300 is good. The aircraft will be hardest to slow down between altitudes 15,000 thru 10,000ft. Maybe a little higher that 15k but something to play around with. Youāll find the aircraft is slippery through the air at those altitudes.

Ok, thanks Deer. Iāll test it out š
Thank you for this
@DeerCrusher Apparently the landing speed listed above by you is way too fast, especially the 155 knots approach speed (Vapp).
As per Airbusā actual aircraft characteristics file, even at maximum landing weight (MLW), the A350-900 should be at 140 knots, while touching down at 135 knots.
Even for the A350-1000 which is longer, the 4% larger wing area with longer trailing edge would enable it to have a Vapp of 147 knots & yet the same touchdown speed or (Vref) of 135 knots.

Shouldnt it be flaps 1+F for takeoff. I use this setting even on heavy load and itās fine.
No. On shorter runways 1+F is not sufficient
@DeerCrusher posted this above which answers your question. Use your own good judgement to decide which setting is best.

Iād say to use 2 or 3 is not realistic for take off In any airbus as it creates too much drag for climb out.
Unless itās a super short runway which itself is not realistic as no A350s services operate out of short runway fields.
Until you can tell Airbus that theyāre wrong and that they should only use Flaps 1+F as youāre insinuating, Iām still going to go by Airbusā textbook figures. 1+F, 2, and 3 are all used for Takeoff. The data I provide isnāt just something random I pulled from thin air. I wouldnāt mislead you guys. š

Can you make the same (t/o & ldg) profile for the b772? I canāt find much information myselfš¤

Once the reworked B777 comes out, new information and maybe tutorial videos will be available as itās a more up to date version of the actual aircraft itself. Keep an eye on the #tutorials category after the B777 rework is released. If Matt is feeling extra nice and thereās no tutorial video, maybe heāll make one. š

Hopefully, itās just because the tutorials are very general but this profile has the specific performance dependent, on the weight of aircraft. š¤©
Yes. I can make another one like this. We do have a 777 pilot in the group and he may school me on the numbers that I put in the table, but the numbers that I do put up will be conservative values to ensure youāre not too fast and not too slow. These will simply be ball park numbers. š

Thank you for this information! Itās very helpful. It would be needed for every planeā¦
