Start-up TGT peak
-
Good afternoon,
In the current version of the sim, the start-up TGT behavior is somewhat incomplete.
Normally, as you bring fuel, the TGT will quickly increase to a high value (usually around 700deg C, with some random spread depending on engine time, tailwind, OAT etc...) before dropping to idle TGT value as the N2 spools up. The pilot will activily monitor in order to prevent a hot start situation.
I made a graph from values obtained on the real 146-200:
You also can clearly see this behavior on the video below, at 1:10, for all 4 engines:

I would not be surprised to hear it's a limit of the MSFS default engine model (indeed, default airplane doesn't see to mimic this behavior). But I don't know, maybe there's a workaround of some kind, those details are nice to have :)
Thanks !!

@Genista Our sincere apologies for not responding to this sooner. It must have been missed amongst the increase in forum activity during the initial release of the 146.
As you correctly assumed, the engine behaviour during startup in the 146 is currently controlled by MSFS, and we only have very limited (if any) control over the engine behaviour until after the engine has reached ground idle after engine start.
To add a TGT peak and to simulate hot-starting would require a custom-built engine model, which is a little outside of the scope of the project as it stands. Improved engine simulation is something we would like to eventually add to all of our aircraft, so this may be something we include at release in one of our future aircraft, and then back-port it to the 146.
We do have this feedback logged on our internal bugs/feature request tracker so it is something we will consider during development of our future products.
