Passenger weight

Why would you want to change the default weights?

Because in the USA they vary between winter and summer. See TABLE 2-1. STANDARD AVERAGE PASSENGER WEIGHTS of the FAA Advisory circular AC 120-27E.

In the EU they are different for holiday charters and other flights See Table 1 of EU-OPS Subpart J Mass and Balance.

For what it's worth, only the assumed weights change.  Granted, there's some merit behind changing the numbers - more/heavier clothes, trend to pack on a few pounds over the winter - but just because the industry changes the weights doesn't mean everyone is going to be that new weight.

 

As I've stated in numerous threads before, the passenger load is just a notional value.  Weight is weight.  If you want to use a different "passenger weight," make the appropriate change in the ZFW.

Hi,

it's seems to remember that ngx is 80 kg (175 pounds) per pax.

If you want to calculate (almost) precisely your pax weight you should firstly establish a ratio among male, female and children pax (i.e. 150 pax of which: 80 males, 60 females and 10 children) and then applying the standard weight according with rules (FAA/JAA or your country's i.e. male=78 kg, female 68 kg, child=12 kg) and then consider hand luggage (in europe usually max= 8 kg) and max cargo luggage (in europe usually domestic/inter european flight=20 kg) then summing up and applying this weight to the ngx load..

 

Ciao

Correct, 175 for the NGX and 195 for the T7.  This becomes important on the NGX and TopCat for example, if you wish to distribute the payload in the FMC according to the values shown in the TopCat Payload distribution page, after it's exported from PFPX.  Abviously we are still waiting fot PMDG T7 in Topcat at this time.  But, Christian does have an acrtion-item on his to-do list to make the weights part of the PFPX aicrfaft profiles vice the current method of a single Prefernce for the entire PFPX program.  This will negate the need to change the weight prefence every time we switch aircraft.

If you're just using PFPX, remember that to get it to match PMDG weights you have to modify the default "Weights" settings. There is only one set of weights so you have to modify it whenever you change from 737 to 777.  They have an item on their to-do list to create multiple weight profiles.
