bank velocity vs. bank acceleration? Please explain!

Recommended Posts

Hello,

 

I am fiddling around with autopilot settings and came across these two:

max_bank_acceleration

max_bank_velocity

Can someone please explain the difference between those?

Actually i am trying to reduce the way the TBM's AP banks. I have a feeling it is too violent so i'd like to reduce the rollrate and the reaction time the AP needs after a new HDG is dialed in.

Right now the AP immediately starts to roll the plane when the HDG knob is manipulated and it feels a bit too fast.

Is there a way to set it to a little softer motion?

 

Best regards,

Tom

Acceleration is the intensity of ehich it can go from stationary to moving. Velocity i would assume is the rate or speed at which it turns.  Thats just roughly going over those terms.

Just as Armchair pointed out above, the acceleration is probably what you're willing to fine tune because it may well respond for the abruptness in the roll rate as the AP tries to capture it's desired bearing / path / heading / LOC ...

The speed component can OFC also have influence on the "feel" of how fast the aircraft is banking, already at a constant roll rate, after the initial acceleration, so you could further fine tune through that variable as well.

 


Use your flight simulators with a well defined purpose...

Don't expect them to be "perfect" or to fully cover all aspects of simulated flight...

Try to enjoy it instead of stressing...

So acceleration is basically the time it takes to reach bank velocity?

Ok thanks alot! I'll give them a try tonight.

Keep in mind bank acceleration in the autopilot settings works both ways. It not only sets the rapidity of the initial bank but it ALSO sets how quickly the bank stops. It works in concert with max bank velocity in a critical way. The balance is to not set acceleration too high but also not set bank velocity too high either. The best way is to set acceleration so it is smooth but doesn't lead to an over-run in desired roll. It should gently, but not ponderously, get to the desired heading just as the wings are level.

Yeah i was expecting that. Is there a good rule of thumb to start with?

I think this is pretty much trial and error isn't it?

Bank_Velocity is the speed by which your bank account is being cleared out by addons.

Bank_Acceleration is a measure of the increase of your obsession with flightsims over time.

 

Thought everyone knew this...  sheesh
