Flight Dynamics

[ＲΞＴＲＯＬΛＤ]

So after enjoying go through the shallow learning curve of this jet for a while, and reckoning it was known for it's sharp response to control inputs, I found it understandable how sensitive to maneuvers the the model is, until the recent turn for the worse in weather around the Mediterranean coast... On which am having a hard time keeping under control and preventing from banking too much under moderate to severe wind gusts or rain [usually upon climb out from Nice] it gets tossed around like a much lighter plane would, sometimes it's quite scary. Was it really that twitchy in real life?

You dont mention anything in regard to airspeed in relation to turbulence penetration though .... or your operating weight .... either of which could have some bearing on what, you say, you've experienced.

I can only comment are as follows ....

- FS weather generation isn't necessary all that realistic .... "in terms of its impact upon virtual flight" I mean, so, some experiences possibly need to be taken with a grain of salt.

- Not all flight behaviour can be accurately replicated within FS either .... simply because of the limited number of paramters available for exploitation within the host program.

- Having spent "weeks" testing each version of the MERCURE prior to its release I can't say I've ever experienced anything that's alarmed me in regard to the sensitivity/oversensitivity of this simulation (although there's no way I can mirror your WX environment) .... in fact I've always found it as pleasant and stable to fly, in most conditions, as our B737's which are the nearest other aircraft (in terms of size and capacity) in the MERCURE class.

Oh yeah, my fault for not giving any of that information right away (*ﾟｰﾟ)ゞ So here it goes, weights usually park between 48t and 51t, and as these situations happened between 6k up to 14k ft, I kept 250 kts, no AT by the way, up to 10k and then accelerated to 280 kts as per manual indication above that. Moreso I use ActiveSky and it was only accusing a few TCU and rain on the vicinity I also use have that wind change attenuation feature activated on FSUIPC, to make things more clear I am not complaining or anything, simply want to discuss the characteristics for I had done the same legs on different planes of similar size and they seem to handle the bad weather better than the 'Air Inter Fighter'.

It may be worth to note that the Mercure aerodynamic coefficients were tuned with advanced methods (academic aerospace software!). The default FS aircraft are very conservative and seem to over inflate pitch/roll/yaw damping coefficients. This has trained most FS folks to expect something from an aircraft, but the real things are way less rigid. On the other hand, the Mercure is less rigid, but more dynamically stable than the average FS aircraft. It will roll/pitch back to level if perturbed. Abrupt control inputs will result in PIO (Pilot Induced Oscillations) as well. Turbulence will toss around real 747s, but in FS heavy tourbulence just tickles the default jumbo a bit...! THe Mercure will take the hit instead.... enjoy!
