Hello everyone, I’m making an attempt to bring this issue to the attention of the MSFS developers by asking them about it during the upcoming developer Question and Answer session due to be held live on Twitch on January 27, 2021 6:30 PM (UK time).
Here is a list of adverse yaw effects we study at PPL level wich imo is the very basic.
Keep in mind there are some Wanted yaw, (as the one needed for a coordinated turn.
We also can break all of these down to a relation with relative speed/density of air.
Like someone said in this post , lift off in a cessna 152 from a track at 40 knots , while it is (possible) leaving the ground effect should bring you right back on the ground effect.
All of this is very basic understanding skill for a real pilot.
I know modeling must be a big job but as far as SIMULATION, you can’t cut the corners round.
This thread covers most of the missing prop. effects you are mentioning:
By the way slipstream, asymmetric thrust, torque (theoretically not a yaw effect, only on the runway this will cause yaw due to difference in wheel drag), gyroscopic effect (can be a yaw effect when pitching) and P-factor are not “adverse yaw”, adverse yaw is solely the yawing caused by difference in induced drag during turns. But I get your point.
On a low power piston engine I don’t think the torque effect is much noticeable though, the other effects, primarily slip stream has a far greater effect during take-off roll. The only time I ever really experienced the torque effect is during stall with power ON, you will notice a slight roll not very strong either. On high powered aircraft it might be a different story though. Highest power single engine prop I’ve flown was a G36 Bonanza, only a few hours and I didn’t do any stalls in it. Otherwise I’ve flown mostly 160 / 180 BHP pistons…
that is exactly how they teach it in school. but think of newtons law, every action = a reaction…
I personally think this: (the moment you increase or decrease the engine speed) is a yaw factor …
Since you add more force on one wing (depending if you add or remove some power) then the friction from the aileron required to maintain a flight level should also be a yaw factor… I know it’s a stretch but I know it’s there
Yes the prop turns clockwise, so the airframe experiences torque and has the tendency to roll (not yaw) anti-clockwise. You might need to use ailerons to compensate which creates some trim drag which in turn creates a small yaw, but the primary effect of torque is roll, not yaw. Otherwise I agree .
Dude! Click on Ninja’s “Nijntje91” avatar and read his profile. I’m not saying he’s never wrong, but be aware who you’re debating with. That being said, if you were just trolling him for fun, then have at it!
Oh and btw, slipstream effect is mostly countered by making the tail a little offset. The fact it has been fixed doesnt remove the fact that it exists. In fact in my opinion, it shows that it is strong enough so they needed to take action against it.
