According to the ‘saved airframes’ aircraft has an empty weight of 2634 kg. According to the remarks in the flight plan, this includes 2 crew member, each of them has a weight of 77 kg. So basically your Empty Weight is the Dry Operating Weight (DOW) because it includes crew weight. The ‘real’ Empty Weight would then be 2480 kg.
According to the flight plan, payload is 500 kg, cargo is 115 kg. Calculating ZFW is usually done using the ‘formula’:
EW + Crew + PAX + Cargo/Freight = ZFW
2480 + 154 + 500 + 115 = 3249. The flight plan shows a ZFW of only 3134 kg which is 115 kg less. Surprisingly the difference is the Cargo weight. Coincidence?
Hi, the PAYLOAD line in SimBrief already includes all passengers and cargo in it. You should not re-add the 115 kg of cargo to the payload number when calculating the ZFW.
The CARGO line in your flight plan is simply showing you the baggage weight of the passengers (5 x 23 = 115), since you have not planned any additional freight on top of this.
So in your calculation in the first image, you are essentially including the passenger baggage (115 kg) twice. The raw passenger weight is 5 x 77 = 385 kg and their baggage is 115 kg (which appears in the cargo line), giving a total payload of 500.
Best regards,
Hi Derek,
Thank you very much for clarification. So the ‘formula’ is:
Payload = PAX + CARGO, where CARGO = Baggage + Freight
Yes that is correct.
