I've just been out and back from Brussels. I took my standard Urban Kit onto the plane in my coat. I'd removed the knife and scissors from it. This left:
Tobacco tin
6 feet of quality tape to seal tin
Hadson Turboflame Windproof Lighter
Mini Cyba-lite LED flashlight
3 Starlite SL3 6mmx 50mm fishing lure lightsticks (last 12 hours each)
Fox 40 whistle
Mini slotted / cross head screwdriver
Small pair tweezers
Scalpel Blade
Magnifying Lens
12 assorted adhesive plasters
2 Paracetamol / Codeine tablets
2 Piriton Antihistamine tablets
2 Alcohol free cleansing wipes
Sewing kit (2 needles, 4 safety pins, 4 hanks of thread, 2 buttons, 1 press-stud)
Suunto Clipper Mini Compass
Small pencil
10 mini fluorescent Post-It Notes
Cash (£40)
Phonecard

The kit went through the x-ray machine and caused no problems.

Hope this is useful.
