Thanks Sam for the detailed explanation.

We have the very latest 530 without WAAS so it seems I am all set to cross
the Atlantic in the Archer.
Now when I fit the extra fuel tank and depart 300 lbs over gross weight am I

Thanks again,

So long as your 530 has the firmware version that gives it FDE, you are
set for oceanic.
