Hi devs, just updating that landing score again with issues on airbus.
After update was fine, now those last days back again with wrong scores.
in others thirds partys: ex: -250 on simfly goes -450
Also for Boeing and I have reported both planes last week via ticket.
No update received yet.
Hi, in the next few days we will verify this and keep you updated. Thank you for the report.
May I ask which third-party apps you used for the comparison?
Also, which flight simulator are you using?

Regarding the landing rate, I notice many times SF’s detection will be different from LRM or Volanta, but sometimes it is not, so I would like to share my experience about the landing rate detected by SF.
After I’ve been observing and testing for landing rate detected, I can say SF’s algorithm has both accuracy and deviation in the following ways. (this is from my own opinion, and it covers both MS2020 & XPlane 12)
For the landing detected, I think SF’s detection rate will come close to very accurate as following:
- If the aircraft sinking rate is not too fast when the plane is about to touch down, in other words, you flare the plane nicely, let it almost float (or give it just a little bit time) before the wheels touching the ground, I notice that FPM detected will be predictable by looking at the instrument.
If you look at the arrow pointed to “100” indicator, FPM rate will be between 100-200 depending on how you hold it (could be drop below -100 a bit if you still pull a stick), this is something SF’s detection is very good and the behavior is the same both MSFS2020 & XP12. (In this scenario, Volanta will result in softer rate, maybe around -65 to 80, which I think, is not accurate, SF’s detection is better since we can land by using instrument, not land by feeling)
-
But if the sinking rate is too much, the aircraft comes down fast and then touch down, even the indicator is the same as picture, the landing rate might not fall in between 100-200. (It might be more than 200 or less than 100, depends on your holding). This behavior is the same as Volanta.
Next is bouncing, I observe from the replay when bouncing detected, and it is really bounce, even just a very very little bit. (Sometimes it interprets as bounce but it is the runway slope itself, not from the landing). There is a scenario, where the main wheels are just ripple, not float after touch down, but just ripple, SF will interpret this as bouncing.
So, I think if this sensitivity can be decreased just a little bit, that would be perfect. (Volanta cannot detect bouncing unless it is really noticeably). Overall, I think SF’s detection is good enough for FPM rate when flaring the aircraft appropriately. I like its accuracy or predictable behavior.
This is from my opinion only, and I’m willing to hear from the others what do you think. So we can share it and find the appropriate algorithm fine-tuning together.

Thats nice observation, but lately even with good landing as your print from rate land, keeps worst on sf. And ive talked with others pilots from sf, and they are complaining as well(with others brands of airplanes).
And other thing as well, (this with me, but can happen with others pilots) ex: you make a good land rate -50 and hit the target on runway, that was suppouse to give 95/100 that is going 60/100 or 80/100 and i did one good landing that counted 6/100 even with a good land.

Hi gunslinger,
I understand what you mean, and if you haven’t done so yet, I invite you to read how the Total Landing Score is calculated on SimFly. The current logic does not mean that achieving -50 fpm with a certain aircraft automatically represents a correct landing. In our system, several other coefficients and factors are involved, such as the aircraft model, the current aircraft weight, wind conditions, and other operational parameters.
That said, I would like to thank metrocat for the detailed analysis he provided, and also all of you. It helps us a lot in case we need to calibrate or improve some parameters.
Thank you all. I will keep you updated if there are any changes regarding this. It is an important point that I believed was already well established with the community, and now it is even more so, especially because the new Touch and Win mission will be released soon.

yes, we know that landing analysis from simfly, but still wrong evaluation from score, please check(review it), cause isnt with only one or two pilots. A lot of pilots are complaining without be here on forum. And its with a experiences pilots that are complainin.

Just updating!
A20neo with wrong fpm land rate.
A332 and 388 is fine, but 20neo back again(i thought was some of my landings) but after fews compairson with others third apps(volanta and other flight company) i needed to share.
Thank you again
