GYPSY.
During MY period . At the end of the first year as sergeant pilot promoted to flight sergeant automatically, after the end of the second year promoted to W/O automatically . With regard to Cranwell, as far as I know Cranwell was solely for officer cadets, and we did not have any Cranwell officer cadets on our course, only university air squadron types. But please if any one can enlarge on, or correct this, do so.
