Just as the subject says, I am trying to find what was the max zfw for each series of the dc9. any info or links would be greatly appreciated! my internet searches have been fruitless. thx

That information can be hard to source with absolute precision .... partly because it can vary considerably between operators even of the same aircraft type/series. One might find "relatively accurate" data for 1 or 2 DC-9 versions (any aircraft type in reality) but often not for every version that makes up a particular family/flight line. And even when one does find such information, and then compares that with other scantly available references, it can be significantly "contradictory" .... again for the above stated reason. The way we/Mike and I did it (and still do in fact) is to record a types "EMPTY WEIGHT", as stated within the WEIGHT & BALANCE section for each DC-9. This data should then be displayed within the FUEL & PAYLOAD ADJUSTMENT schematic upon selection of any aircraft type in FS. This data was sourced from official references back in 2009 when we compiled these simulations. Stick with the EW references we've quoted. They're the "best/most reliable" data available .... and if it's was out (it shouldn't be though) then it won't be by much at all and certainly not sufficiently as to impose any major difference/s. Don't ever be tempted to try'n alter WEIGHT specifications stated within any of our CFG's though. Such could have potential to throw the MOI's out of whack (everything's calculated in accordance with a number of parameters and for best FS performance/s) .... and which could then result in "problems". I just felt it prudent to mention this .... based on our experiences with "other people" in the past ![;)](//storage.proboards.com/forum/images/smiley/wink.png) Mark C AKL/NZ

ok, thx, yea, i'm not altering anything in the w/b sections, mostly looking for this info only to use with FSPassengers as usually it will start you with less than max passengers, so theoretically i could carry more cargo weight and earn more revenue ![:)](//storage.proboards.com/forum/images/smiley/smiley.png) , but don't want to exceed mzfw so it won't mess up epr values or other dynamics. i think i'll take ur advice and just add the station weights to the empty weight. only thing i ever found online was an "estmated mzfw" for a -20 series of about 69000

"THAT" (weight) .... sounds a bit high "to me". We provide 2X different DC-9-20 configurations. 1X representing the JT8D-9 .... and 1X representing the JT8D-11 .... since both engine types were used among the few DC-9-20's built and for which minor weight variations applied. As I earlier mentioned: The EW's we use (for everything .... and not just the DC-9's) are based on the best official sources we consulted stated back in 2009", but, this data, will again and almost certainly, differ between operators and aircraft configurations .... albeit not by much (for the -20's). Our DC-9-20 JT8D-9 version is compiled with with an EW of some 52,644 LBS and MTOW of some 98,000 LBS .... and our DC-9-20 JT8D-11 version with an EW of some 53,200 LBS and MTOW of 101,000 LBS (I think these aircraft, like most types, have MRW that's a little higher than their certified MGTOW). Not a big variation exists between either of the -20's supplied by us, but, what's compiled "is" sufficient to ensure a wee bit of performance variation is evident "in FS" .... even based on just weight and engine thrust alone. "IF" .... using the DC-9 panels we offer (FS9 portable only at the moment) then always use the Weight Computer (in the panel) and which will automatically compute TO/LANDING V-speeds (set/bugged within in the IAS gauge) in accordance with actual simulated weight at any time. As may be noticed by now .... each of our DC-9 panels (in fact nearly every panel we offer) is "aircraft type/engine type specific" .... so .... it's essential to use the correct panel version with each simulation (or don't hesitate asking us for advice ![:)](//storage.proboards.com/forum/images/smiley/smiley.png) ) otherwise the like of V-speed computations, in relation to simulated weight, will be "OUT" and performances may then be penalized (+ or -). Some, but not all, of our DC-9 panels also feature an EPR Computer too (from memory I think this applies to just the DC-9-40 and -50 panels only) and which will automatically display EPR limits primarily in relation to simulated temperature and geographic altitude environments for TO .... and also in relation to CLIMB and CRUISE power settings too and based on the same primary references. The DC-9 panels we offer are actually quite nicely featured albeit with their "current" FS9 restriction, but, we hope to be able to offer "a bit of surprise" relation to these later during the year .... all going to plan.

"THAT" (weight) .... sounds a bit high "to me". sounded off to me as well so haven't used it. i do make sure i always have the right panel and aircraft.cfg for the series/engine variant i am using and have no issues of real concern. having said that, REALLY LOOKING FORWARD TO WHATEVER THAT SURPRISE LATER THIS YEAR MIGHT BE!!!
