No problem Marc, just refer to the 747 performance manual and apply the same corrections for the snow depth to the take off weight of your Reaper !

Seriously guys, don't get too upset about your cold climate, we got trapped in Sydney last night because of bush fires which are now very serious.
I,d rather be trapped due to heavy snow than raging fires !
