Hi, i am still having issue with default fenix pax weights (it has default pax weight - like 79kg + 15kg bag) it always load aircraft with these figures. When you have full A320 with this numbers you are ALWAYS above max payload. This is the fact. The thing is i want to simulate that even if i have full plane i want to have much less payload (like more kids are travelling or pax just with hand baggage - it is much more common compared that all pax weigh 79kg+15kg bag). Ofourse i may edit it in simbrief, but even that, if i load fenix with GSX, it takes just the fenix internal numbers (79+15) and the planned ZFW is ofcourse different from the one planned with simbrief with less weights. For example in FBW A32N, there is an option in the EFB how the plane should calculate pax and baggage weight.. in this case, it works, but fenix is not able to change this, or is there any walkaround to this ? I dont mean to load less pax.. i know, but how to deal with this.. full plane but less payload.. This does not make sense, even lowcost airlines if they have 180 pax onboard, payload is approx 10-12tons (combination of kids, women, pax carrying light suitcases), in fenix, you get almost 16tons everytime. Thanks for hint. Jan.
Hi Jan,
What you need to do is create a custom profile/airframe in SimBrief that lets you adjust the luggage weight.
The standard profile is indeed set to 80kg per passenger plus 15kg of luggage, which doesn’t always reflect reality. By reducing the luggage weight, you’ll start to see more realistic ZFW figures.
As a realism enthusiast, here’s what I personally do:
I’ve set my SimBrief profile with 80kg per passenger, which in reality accounts for a passenger plus their hand luggage, and set the luggage weight to 0kg.
Then, I manually add the weight of checked luggage in the “Cargo” section when planning my flight. This lets me adapt the payload to different scenarios depending on the flight type.
For example, for a typical low-cost carrier, only 25–35% of passengers usually travel with checked luggage. Let’s say we have 170 passengers. If 25% are carrying checked bags, that’s about 42 passengers. A typical checked bag weighs around 13kg, so you’d add roughly 550kg of cargo.
SimBrief would then calculate the payload as 170x80kg (passengers) + 550kg (cargo), totaling around 14,150kg — more or less it will also consider the crew weight. This is much closer to what you’d expect for a low-cost carrier.
Then, you can tweak this depending on the flight type. For example, on holiday flights (e.g., from Northern Europe to the Canary Islands), you’ll often see more passengers with checked luggage, and the bags themselves might be heavier, closer to 16–17kg.
Hope this helps and makes sense! Let me know if you have more questions 
Hi a thanks for answer, i fullly understand what you are writing about.. actually the problem is not with simbrief but with fenix.. Fenix does not take into account any changes i make in simbrief.. I had several airframe options like what you desribed in simbrief, reduced weights for short european flights (without checked baggage), holiday flights etc.. but Fenix never takes into account ZFW computed in Simbrief (if it is different from default calculation with their simbrief profile), it ONLY take number of PAX multiply it by 80 + 15kg luggage each person. Every time.. So i have a simbrief plan with reduced pax weight, for example full plane 180 pax, but with avarage weight lets say 60 kg+ 5 kg hand luggage, so i get reasonable and adeqate ZFW according to this..
but Fenix takes just the 180 pax and do what i described,.. so i get o loadsheet and plane is loaded like i have 180 pax with 80kg+15.. edited simbrief profile does not affect the fenixs internal loading system..
I hope i described it clearly :).
Thanks, Jan
That does sound odd! Let me put together an example for you
The Fenix loading system always calculates 80kg per person and this value can not be changed.
However, it does not include any luggage weight which is added separately in the Cargo section of the Fenix Mass & Balance page.
Here’s an example from a flight I did this morning. I set the number of passengers to 168 and added 600kg of freight to simulate the checked luggage.
When I generated the OFP, it calculated the payload as 14,040kg (168x80kg + 600kg) and a ZFW of 58,069kg.
After importing the flight into Fenix, I found the same figures: 168 passengers, 600kg of cargo, and a ZFW of 58,069kg.
These numbers also matched the loadsheet.
I’m not sure what might be causing the discrepancies you’re encountering. For reference, here’s how my airframe is configured:
Cheers!
Hi, at first thank you very much for you effort to reply in a complex way :-). Appreciated.
It does make sense what you wrote, i also tried before to adjust cargo weight manually to have reasonable ZFW, but it ended up that the loadsheet i get was completely different from the simbrief values.
As far as i know, lowcost airlines usually have around 500kg of baggage weight only on regular flights (no checked luggage etc.). But holiday flights they have much more, like 2 tons or so (heavy luggage or more pax have heavier bags), than you cant take them with fenix :-)), it is a joke ofcourse, you get than to very high ZFWs.. because the default weight of pax is 80kg.. but if you count approx number of kids, woman, you get circa 65kg as a median value for pax weight in general, but that is a shame, we cant simulate that, so the only option is to play with cargo..
But for example FBW A320 Neo is capable of changing these values.. straight in the EFB.. it can be adjusted than to your choice.. but anyway we have to live with that if we fly Fenix :-).
Thanks once more, will give it a try and do some experiments.. will see if i get it work..
Jan.
And what i dont like actually is, that full plane (so 180pax) gets you 14.400 payload (180*80) everytime… and this value is without any cargo (so extended to reality - no bags).
and in fenix it is impossible to simulate full plane but with payload like 10 tons only (like if your pax are kids mainly or woman)..
And as we discussed real thing, in reality, you get to 14-15 tons of payload if you have a typical holiday flight, heavy bags etc.. But you cant have less payload in fenix when you want to have full plane as well.. If i am right..
Have a nice Christmas time.
Jan
Thanks, it works flawlessly this way. Problem was, that I tried to manually decrease ZFW before, that does not affect the actual load in Fenix loading system.. It has to be done via the cargo load.. this only could affect ZFW (i mean when using Fenix)..
