Sharp turns using VNAV

[Shomron 2]

Hi,

I've noticed the CRJ Pro takes even slight turns in the max 30 degrees.

It also has some issues sometimes intercepting the next leg and gets into 1-2 S-turns.

Is this normal, the way a real CRJ behaves like?

Noticed the same but also when in LNAV mode only.

Sorry I was referring to LNAV as well

Any comment from anyone familiar with this?

The only thing I can tell you is that I last saw this behavior on the "old" CRJ version.
There a too high speed on the turn was enough for the old CRJ to lose course or miss a waypoint.

 

But already during the beta-tests there was a clear improvement and these S-turns didn't show up when intercepting a flight route, at least for me.
Flying a flight route including SID and STARS with the necessary direction changes also works very well with the CRJPro.

 

Would you have the flight route available where the problem occurred?

It happens every flight....

If the next waypoint requires a slight 15 degree turn (when VNAV is selected) the aircraft will perform a sharp turn to intercept it.

In other aircraft this can be set manually to 30 or max but the default is auto where turns are mostly subtle.

Again the real aircraft may behave this way,  it just seems weird.

We are revisiting max bank angles and roll speeds in all lateral modes and once cleared we will make it available via an update. But this will take still a while.
