Hopefully a medic will reply, but, FEV Forced Expired Volume relates to the size and effectiveness of your lungs. The predicted value will be based on age, height and mass. Your low score suggests to me that you are not aerobically fit for your age and size. Jogging and cycling could improve this within six weeks if you trained, preferably with a heart rate monitor. Perhaps you have been ill, inactive or similar for the last 3 months or so? Good luck at Gatwick.
