[DG] [DG11] Heel angle AWA narrowing on I70s

[sailshade]

Dear All,

for a sailboat wind instrument it is known that heel narrows measured apparent wind angle by 1 /Cos(Heel).
Upwind, with a 30º heel, apparent wind AWA is narrowed about 3.5º or 13%.
Since there is no mention of this fact anywhere in the docs
Nor in the excellent summary here:

I wanted to know assuming there is a heel angle provider on the nmea2000 bus would the I70s compensate/account for it?
What is Raymarine strategy to calculate polar and performance in presence of this parameter.
