Thanks for the feedback, relieved to hear.
Funny fact: if the paper RTOW are smartly configured before exporting, an all live-iteration EFB will not bring much tangible benefit but this is one.
At least Airbus OEM prints the (single!) eoacc alt already inclusive of the required ALT correction to match the coldest temperature displayed on the chart.
Which carries a double penalty against the Max TOW for hot temps. A) the plane is made to climb aerodynamically higher, up over the alt+correction; B) the plane also climbs geometrically higher due isoplanes expansion.
When making a FLEX data departure under the assumed higher temperature, the above translates into a double performance margin inherent in the result.
