Engine spool up time

Post by Themax »

Hello,

First of all another big Thank you for this wonderful model ! :D

What I currently don't like about flying the jetstream is the spool up time of the engines at take off or during go around, etc. I don't have access to the sim now so I can't know how long it takes exactly but if you look at this real video from 1:55 it's very fast and actually way faster than in my fs :

When my engines are stable at take off thrust, I'm at almost 80 knots already.

Anyone else noticing this difference or am I the only one ?

Is it Prosim that is sending the spool up command to fs and that controls the speed or is it in the aircraft itself ?

Thank you,

Maxime.

Maxime,

Although the engine spool-up time is dependent on many factors in the real situation (OAT, air-density, humidity, wear of the turbines, etc.), it is a known thing that FS tends to be a tiny bit slow on spooling. It's not the model, it is FS, but unless you deliberately watch the indicated spool-time on the EICAS, the effect, hence the end result remains the same.

FS does all that, however the model has a value to increase how rapidly the engines react to increased fuel flow, but a too high setting of that has other major disadvantages.
