A320/321 GWFK
The older MSNs I flew have a PARAM ALPHA callup in the box which allowed one to view the GW as calculated by the FAC once above 14,000ft, say at cruise level when everything settles down. One inserted "GWFK".
The later MSNs don't appear to have this parameter. Is there any way one can call it up? "GW" only gives the FMC calculated gross weight as I understand it. I've also attempted GWFC. No joy.
Thanks.
