I would say it is Flight Level 300.. ie times 100... 300 * 100 = 30000 climb to 30000ft That is what I used to give on a take-off.. Ie Maintain Runway Heading 18, Climb to Flight Level 200, Contact Ground Control Intercept on STUD 3. etc...
QFE is atmospheric pressure relative to the airport.. IE the Air Port would have a barometric altitude of 0 ft. QNH is relative to sea level. The airport would have an altitude relative to sea level. I am more used to QNH... but I guess Europeans use QFE ?
