Hi Dave,

Yes. SeeYou gets airspeed and wind data from the 302. The 302

the wind - not SeeYou.

So the 302A not only is a logger, but also has a computer that
calculates wind?

No, the 302 flight computer calculates wind. The 302A flight recorder
does not...

The 303 manual says that the 303 calculates the wind. Why would it do
that if the 302 does the same thing?

I don't understand why Cambridge would go to the expense of putting a
wind calculation computer in the 302 when the 302 always will be
connected to another instrument (303 or PDA) that can calculate the
wind. Basically, wind calculation in the 302 would serve no purpose, it
seems.

The 302 definitely calculates the wind. The 303 is a pretty dumb I2C
serial display, the "computer" is the 302. The *cost* of calculating
the wind in the 302 is likely dominated by the instrumentation
hardware used to measure air temp, pitot pressure and calculate TAS
etc. Since there is already a processor there the additional cost is
just software
