Unknown Target, Flight level setting is really basic altimetry, and should be absolutely standard knowledge for any pilot whose past his 1st solo, let alone 50-odd hours post qualification.
They're nowt to do with 10,000 feet by the way, so it appears you dont know them either. If you're a pilot, I suggest you urgently go away and read the altimetry sections of both your met and air law books before you fly again

PS Did you not spot the Freudian slip in :
