Reduced Thrust take off.
-
How do we calculate this in the RJ, in the 146 in game checklist/flipbook there was a handy table with temps but there is nothing like that in the RJ. Any help or direction on this would be great, thanks.
Also, the tutorial said a reduced temp of 30 would give 92.3 N1, it actually gave like 88.9 or something close too, and that's loading the tutorial with the .FLT file, with all its presets.

I'm also looking for some guidance on this.

There’s a BAe-146 take-off performance spreadsheet available at Fs.to which might provide a starting place; expect a fair amount of data input.
When I write starting place, I mean contacting the author and asking nicely for RJ data values for an assumed temperature rather than N1.
An old FS9/FSX takeoff performance calculator called UTOPIA has the RJ85 (but not the RJ70 or RJ100) and this provides an assumed temperature for present conditions and weight.
Amazingly, this still connects to MSFS 2020 and can automatically populate weather and weight data.
Unless you want 20 year old airport data, you’ll need to regenerate and/or reformat the default UTOPIA data table to better reflect the present day - an hour or so with make-runways and Excel should do it.
You could craft new RJ70 & RJ100 data tables based upon the included RJ85 as these are textual in format.
That’s all OK if you’re happy with basic unproven numbers, and so these are listed here as potential starting places.
However, I’m still looking for an old spreadsheet which used to cover the RJ models that was originally found in the QualityWings forum.
Given the state of my memory, this might prove to be an elusive red herring…

Yes, I'm with you guys, this is definitely something we needs.

Having just re-opened UTOPIA, it supports the "RJ" as well as the BAe146 100, 200, & 300 variants.
I have found the spreadsheet with RJ support, but then this has a tab for the BAe146-100/RJ70, BAe146/200/RJ85, and BAe146-300/RJ100, so presumably the figures for the equivalent types are still correct.
Anyway, it's a start.BAe146/RJ spreadsheet: https://library.avsim.net/esearch.php?DLID=197048&CatID=genutils

I have downloaded the doc, but I can't open it, same for you?
-
I just get "The file is damaged and cannot be opened".
Maybe because it´s a *.ods file, which Excel 365 doesn´t support.Simbrief has the option to calculate Thrust reduction, but in the current profile for the Avro RJ's, this is not enabled.
EDIT
Here is another link with a *.xlsx file that works for the Bae 146.

I was hoping being able to use SimBrief's Takeoff Performance calculation, however it always returns
SEL TEMP = NONE.I assume this relates to missing performance data in the aircraft profile. Is this something JustFlight could collaborate on with Navigraph?
