    I do however get some really high EGT's when starting engines in OAT's above 15 degrees!

    We're working on a fix for the high EGTs.

    First of all thanks a lot for the explanations !

    Climb power should come with a reduction in power but not necessarily a drastic one. From my experience using the 146 pro so far I see a sensible reduction in thrust when selecting climb power.

    how exactly would you select climb power using SYNC on the TMS ? I am still not sure how to do that. If I use the SYNC method as mentioned above, I just get the current N1 copied to the TMS display (as Martyn explained)

    @Mikealpha Try hitting TGT then SYNC. I believe this will give you TGT SYNC mode. Just make sure you have a sensible EGT (780 should work) selected in the scroll wheel window.

    That didn't make a difference. I still get just the actual N1 value copied to the display. Doesn‘t really make sense.

    If SYNC is engaged (pressed) with TGT already engaged (as indicated by the green arrow) then TGT SYNC mode will engage and the selected TGT is displayed rather than an N1 ref value. It's working here:

    @Martyn hallo and , first-things-first, thanks for giving us the best PC based BAe146 reproduction so far!!
    I’ve Flown the real “Quiet Trader” more than 20 years ago ...so please accept my apologies for my very “Fading memories” ( as “Jumbolino” used to say😅) on what I’m going to post in this forum.
    Anyway the aircraft, as mentioned above, is really accurate but I’ve found a little strange there is no way to find a good resource for “Flex T/O”. Toper works only for Boeing Aircraft and TOPCAT has no BAe 146 options as well😓😓😓😓....it would nice if you help us find a reliable resource for this. I mean, this aircraft “works-around” the TMS. And Flex operations are now used on 90% of departure procedures. It’s really a shame such a good add-on cannot use it.....sorry to point it out but, almost all the others add-on I’ve been using can easily use flex temp take-off and climb ( PMDG,FS Labs,MajesticSoftware ...only to name fews..).
    Thanks for your support.
    Regards,
    Claudio

    Hi Claudio,

    There is information and tables for the TMS, including flex, in the handling notes of the manual. We can add more information if you feel there is anything missing.

    Thanks

    Hi Claudio (@Mistral2000), as well as the tables in the JF manual, there's various tools available online such as the freeware Universal Take Off Performance Calculator (UTOPIA) tool. It's not specifically designed for the JF 146 but it does contain type-specific de-rate data based on given runway, aircraft weight and weather conditions. It's pretty reliable and it's free - you can pick it up from various library websites such as Avsim.
    Cheers,
    Craig

    @Martyn hallo!
    Martyn I’ve digged into the manual and on the “Handling Notes” there are a lot of useful tables/graph as well as explanation.
    The point is different: on page 239 and 240 there are two very handy tables which help pilots finding N1 Ref and , eventually, a “Delta” N1 Felx. That is good but , the most important calculation I did when I was flying in the ( real..) BAe146, was finding the “Flex Temp” to insert into the TMS. The only way to find it is using “Runway Analysis or/and Flex Temp Performance Tables”. Since I use to operate the BAe146 on big/long runways I only used Perf Tables in relation to my ATOW and Aiport Weather infos ( Temp , Wind, Precipitation etc..). The best thing would be the so Called “Runway Performance Analysis “....ok Nowadays we have EFB....but “back-in-the-days” we had only “Papers” to work with....👍 if you like , to be more clear I can update to you some Runway Analysis Tables I used in the B737 Classic which was the last aircraft I’ve flown without the EFB....

    The 146 performance spreadsheet available on Avsim does offer the ability to alter the parameters for flex temp take offs, and shows their affect on runway performance. I know its not perfect, but I'm in the process of checking it with my 146 and it seems to work reasonably well.

    The spreadsheet is in the AVSIM P3DV5 Utilities section entitled:
    BAe AVRO RJ / 146 Runway Performance Spreadsheet
