EP#3 Aerodynamics is staggering

Wind shear is a change in wind direction and or speed. It can be vertical or horizontal. It's usually horizontal in my limited GA flying experience. I would fly the approach at a faster speed so not to stall the plane with a change in wind direction. 

I'm not a RW pilot ..but would I be right in thinking as you stated approach speed is raised if warning of windshear is given to a pilot while if it's actually experienced, a go-around is meant to be initiated depending on what stage of the approach is being flown?

That's correct 🙂

I'm not a pilot but I presume wind shear ("down draft" ?) on final approach can be an issue sometimes.

In the real world how do pilots accommodate for this?  Fly the approach slightly steeper than normal? Keep the engine revving higher (but feather the prop?) in case you need to quickly add power and gain lift to compensate?  Just wondering....

If you fly the approach steeper you need less power and that's not what you want.  Don't understand the part with the feathered prop since a feathererd prop doesn't provide any thrust and you only feather a prop at idle power.

The only correct thing you do is to increase the approach speed, the limit is usually around +20 to +25kts.

The 747 doesn't seem to have wing flex either.   I very much doubt any of the default aircraft in FS2020 are study level.... But that's why PMDG (etc) are successful.

Wingflex has nothing to do with study level (and it presently doesnt' any impact on aerodynamics).

Unfortunately since many people think that wingflex is a super realistic feature, some add-ons are having wingflex while the real aircraft doesn't.

Unfortunately some developers actually put so much weight on those sterille aesthetic features which aren't internally translated to any flight dynamics effects ( well, they sort of are in simulators like X-Plane, Condorsoaring, FlightGear some FDMs ... ) that we see users asking for all sorts of "beauties" instead of concentrating of real / useful so called "study-level" features ...

But the real 744 does wing flex a lot sometimes 🙂

And PNG ! Landing on the steep sloped dirt runways there will have to be relearnt all over again !

We may now need to make sure we have some airsick bags nearby when flying around the TCU's and mountains!!🤢

LOL, just wait until VR arrives!!

I'm a bit skeptical, as the wings of the a320 are rigid. They do not move vertically one millimeter. 

No, but airflow still affects them

So maybe approaches in FS2020 will be a little treacherous under certain conditions?

I would say the peril is also the mountainwave phenomena, which is clear air turbulence incl severe downdrafts. Now mountainwaves are usually found in mountainous areas(!) with atmospheric stability where wind is perpendicular the mountains. This is very important to be aware of.

Flightschools (at least mine did) dedicate lots of attention to these conditions because most of times the danger can't be seen (aside from altocumulus lenticularis clouds, if they have the conditions to form).

All this is good , but we need hands on.

I think the solution to the wing flex observation is, “alpha”.

I watched a really good video on this once, if I remembered what it was I’d link it but it’s in YouTube somewhere. It was a Cirrus flight instructor flying around the french (I think) alps explaining how all the air would be moving around and why there were certain types of clouds in certain places etc.

As someone who mostly flies low and slow through the mountains of Alaska in the sim, I'm thrilled by the depictions they showed of terrain influences on the airflow. 

Your plane should be getting pushed up on the lee side of passes and pulled down on the windward sides.  Your plane should be getting abruptly sucked toward passing valleys on the lee side and pushed away from them on the windward side.

We may be getting that.

I wonder if they are gonna simulate wake turbulence. With the current tec i really dont doubt they can.

That video is great. It really shows how the wings are flexing independently of each other.

So the wingflex we've seen in P3D with PMDG is just a "canned" animation? 

In FS2020 we could see something similar to the video.

I'm getting the impression that in FS2020 landings are going to be trickier than P3D and "edge of the seat" a lot of the time....
