fokker100 take off flap affects on performance
With due respect, if I was the Original Poster and had recently done two flights on a Fokker 100 and had noticed that on one take-off the pilot used trailing edge flap and on the return (from Innsbruck) he did not, your answer telling him that the F27 had a thick wing, slow cruise speed and no leading edge devices would have hardly enlightened him as to why this may have been done.
