...The 320 uses varying bank angle when turning inb or outb in a xwind (most
obvious in a strong one) to maintain lateral track in NAV. This has an impact
on the total time for one lap. In such circumstances one can fly raw data and
triple the drift for a 1 min hold etc, arriving over the hold fix on time in XW of
50kt or more clean, 40kt or more CONF1, at GD+5 and F+5 respectively.
I use the same scale as Bula.
