How does Oudie IGC derive TAS and Wind? Especially when there is no thermalling. It does not have Ptot/Pstat input and does not have heading info.
The TAS (5 bytes) and GSP (5 bytes) are recorded in the *.igc file --in the B-Record, as configured by the I-Record.

Also--quantities TRT and VAT are recorded. What is that?


Thanks

Found this Oudie was connected to an S80. So--mystery solved.
