Thanks GF, no that's not the problem! I have some data readouts from an FDR, which give me the flight parameters once a second, and I am trying to extract what winds the aircraft was actually exposed to as it descended, in particular whether there were big changes (shears /gusts etc). And I no longer have my trusty old Dalton E6B!
