At what Weight percentage will APPR work?
Sometimes i get the message of my craft being too overweight when i try to use it
The exact weight percentage varies by aircraft.
I would advise using some sort of flight planner (such as Simbrief) which will give you appropriate weights so that you don’t end up above max landing weight (and therefore can’t use APPR mode) when its time to land.

Benny I use Simbrief yet the A320 always seems to be overweight for APPR. Last flight i had 11% with the amber warning colour and still it gave that warning!
That’s…interesting considering Simbrief’s default A320 profile has a MLW 500kg lower than IF’s A320.
I suggest in future when you’re in the planning menu, adjusting the pax and weight figures so that you will be comfortably below MLW when you land (and therefore can use APPR).

Do i just have to be below MLW or there is another threshold below MLW for APPR to work?
Nope - you just need to be below MLW.

Varies by aircraft, but you can always look at the load when planning your flight. MLW and MTOW are values that contain the empty weight of the aircraft so to find the percentage you have to subtract those values by the empty weight. Here is the formula you can use to calculate MLW percentage.
It’s a bit different from calculating the takeoff load percentage since you don’t have to consider the empty weight of the aircraft (for the nominator)
In IF, I found that the average bodyweight for most aircraft is 77 kg (170 lbs) so I always assume my calculation based on that value.
And last but not least, you’re always welcome to use my airframes for your next flights :)

You need to be under MLW
Hi, Yes, like others said, just be below MLW by the time you’re ready to hit the APPR button.
Although a bit of cheat on realism, in extreme cases you could note whether the aircraft you’re flying has the fuel dump button. If resorting to that, just make sure you’re high enough for the dump to work.
But otherwise, MLW is a high enough number usually that you can do the planning to be below that number without having to be super precise on your initial fuel load (having fuel sufficient for a balance between enough reserve and getting below the MLW number).
