Did it also in a PA38 from Biggin a few years back and like a previous post had said its silly prices but check the fuel price now if its like OST/EBOS then best you arrange a second mortgage
Just coming slightly off this thread -Went in to OST last month got an instruction by ATC to go around as some holiday jet was pratting about on the runway and then wait for it...Got a bill for the privilage on top of the usual lndg fee! And fuel price there sucks - BEST AVOIDED!
