I’ve heard some people here say that they use 20% trim on final aporoach. Should I do this, or should I stick with the negative trim I used for descent?

never use negative trim on landing
I recommend using this topic to help decide which trim setting to use depending on your payload and aircraft

Ok. And what about when I start my descent?

Hey man, these are all great questions that can definitely help improve your flying experience in Infinite Flight. Fortunately for you, there is an amazing resource that provides the answers to many question you might have about flying, controlling, or other uses of Infinite Flight, it’s called the Infinite Flight user guide!
At the top of this website you’ll find ‘user guide’, press that and it’ll lead you to the page. Below I’ve also linked the page for descent planning which might help answer your immediate question:

I usually don’t change my trim once I set it after pushback.

Trim is basically to pitch your nose up for better landing and good drag. I personally set to +10 during landings and takeoffs but never used in negatives. Descent can be managed by VS.

There are those guides that show you how much you will need, and I often use those for takeoffs and climbs, but with approaches I just prefer to add it as it’s needed, meaning I just add more as speed decreases. It’s also just difficult to memorize all those numbers and flight conditions can vary so much. With most commercial aircraft, it typically ranges about 40-50%, whereas with the 747 and A380 I often end up having to use close to 100%.

Depends how heavy you are on final what aircraft you fly and in which angle you calibrated your device could also affect what trim you need

Hello, your trim depends on the weight because at low weight using high trim will be pushing your plane upwards and lower trim will push plane downwards. Basically at 10-40% weight use 20 trim. At 40-70% weight use 30 trim and at 70-100% weight use 40 trim. Depends on your weight. Also you can use flaps to make your approach more stable.

Start your descent when VNAV is available. Just turn it on and it will descent for you. Make sure in your flight plan there are altitude to descent to. The VNAV will follow it and take you to the right altitude you want at the right time.

Infinite flight has this amazing tool within its flight UI! Take a look at the trim control button, sometimes you might see a pink bar moving up and down based upon the movements you make with your device. Try making that bar disappear! What I experience is that when I make the bar go, my trim is perfectly balanced to what the aircraft needs.
For me, that usually is anywhere between 20% and 40% trim.

I highly recommend a trim between 10-20%. You’ll be saved! From experience of flying a variety of aircraft on IF and maximum loads I can tell you this works!

TLDR: use whatever feels the best

It heavily depends on the ac you’re using, weight, winds and so on.
A DC-10 needs a trim up to 60%
Others like the A350 barely no trim at all.
What I’m doing: take a look at the trim button and the pink indicator. It should be level/not visible, than you’re on a good approach setting. Adjust it if needed while decelerating your speed on short final.

If I can offer one peice of advice that hasn’t been mentioned yet, older planes (not yet reworked) typically require a higher trim than reworked planes, this isn’t always true but it seems to be the case for majority of them

I don’t focus so much on the number as I do on the feel. This is like real life; it’s about feel and how you need the controls to be.
If I’m at 20% and I feel like I need more or less, I’m not gonna be like “oh well everyone on the community said 20-25% so I have to stick to that”
But generally for most aircraft 20-25% is what I use but it doesn’t have to be those specific numbers if you need it to be different

You should never use negative trim in my opinion
I’ve always found that at least 0 percent trim is required flying, but never below 0
