What type of calculations would be of interest to you (in millibars)?
That
is something we could add to WingX is a fairly short amount of time.

Basically, anything that involves pressure. Most pressing being calculation
of Density Altitude.

WingX looks pretty impressive - what would it take for a user to replace the
FAR regs with CAR (Civil Aviation Regulations)? Ours appear to be modeled on
the FAR 'part' system (Part 61, Part 91 , Part 135 etc) and are all
downloadable in PDF Format.

Cheers,
