Whenever i fly the reworked A388 however Many flaps gears and spoilers i use IT doesn’t slow down with minimal vertical speed.
I am seriously rethinking on flying IT again .

Hey there!
The A380 is a pretty slippery aircraft, meaning it has a hard time slowing down at steeper descent rates. Generally, more than -2000fpm is not recommended.
I’d advise you to take a look at the guide linked below, and the Quick Reference Guide section of it in particular.

Even if i start at 16000 fit reducing to 250kts the problem is after that.
After the 10k ft barrier IT is slippery
Same with the 777s and the DC-10/MD-11. Reduce your speed before reaching 10k ft to 240, and then use the spoilers to avoid your aircraft from gaining speed once below 10k.

The 77s Are great no

Idk abt the other ones tho.

Because that’s how the plane performs IRL. You either slow down and don’t descend, or descend and don’t slow down. Never both. Spoilers will contribute to either an expedited descent rate or an expedited deceleration when at or near level, but it won’t do both at the same time. Like Alex said, shallow descents below 15000ft are how to keep speed from increasing.
We had a former Emirates A380 captain provide his input in the A380 development. If you don’t like the way the plane flies, fly something else or learn to manage your airspeed and energy better.

Hi, that generally can’t be true. Can you provide HUD screen shots of the exact scenario to help diagnose the specifics?

From replay i Count soul understand anything.
Even with spoilers the Plane overshoots.
Multiple flap settings.
So should i step descend?
Re-read what Alex and I wrote to you. We told you everything you need to know about how to manage speed and descent. The plane is fine as it is.
And no, using flaps at high altitudes to slow down is only increasing the need for negative pitch, thus decreasing the effects of the minimal drag the flaps add while increasing your speed.

ok so i should se the a388 guide above?
ok.
thanks all.
so i se the right amount of flaps for landing and the speed ting will settle?
ill try it on the houston flight then.
After flying on the A380 numerous times in real life I’ve noticed it does deploy its speed brakes quite high in the air and keeps them for prolonged periods of time unlike the B737 and A320.

I think it would possibly be helpful to the OP if they could upload specific examples of the issues so that you could point out how to fly in that state to avoid the problem (if they feel ok with that).
It would presumably be helpful for any other readers possibly experiencing such issues (the effects of the A380’s high L/D ratio, glide ratio), to learn by example.

That’s so cool how did you manage to get him.

General rule of thumb with the 380 is the same as the 350, 777, etc., which is to not dip below 0 degrees of pitch under 10-15K feet. Doesn’t matter if spoilers are out or stowed. Just don’t go into the negative pitch territory.
You can reduce speed further while higher (I don’t recommend this btw), giving you a buffer room to descend faster as you regain speed, but at the rate of acceleration on descent, it’s not gonna give you much time. Maybe an extra few hundred feet at most.

That definitely seems to make sense.
To the op: If there’s anything around what was mentioned still causing any uncertainty, don’t hesitate to upload the screenshot example. But, try to make sure the screenshot includes stable flight to the extent possible (forward speed and vertical speed mostly stable).
I find that with the A388, you need to plan your descent to arrival and approach and monitor your IAS and VS very carefully. Slow and steady (and maybe even early) descents work good. Decreasing speed before descending also helps a lot (I tend to use my flight spoilers during descent) because the A388 does not like slowing down while in a negative VS

IT worked!
I usred spoilers for everything until i reached the Desire speed.
No everspeeds,

i cant find a B787 guide to this tho.
does this mean it is the secret reworked aircraft?
or 767?
dont use flaps on descent, only on approach at least within 25 nm from the airport. It will make the descent worse and more unrealistic
