Hmm, the meter/feet thing is not a problem at all.
It is just a number on maps etc. and the one on the altimeter.
If the one on the altimeter is larger than the one on the map you are
save as long you do not bust some restricted airspace.

It is only explaining to non-pilots what speed, altitude you are flying
that needs some calculations.
Roughly: 3ft= 1 meter and km/h = kts x 2 -20%
I give up trying to explain things like TAS vs GS, MSL vs AGL and the
like.

To be honest, there is one slight problem with this imperial/metric
thing.
Having a metric plane with a lot of US/UK made parts on it.
You need a very keen eye to grap the right spanner the first time.

Anyway, most pilots here fly VFR and just for fun.
There is hardly any need to take a light plane to go anywhere for
business.
Where I live it is faster just to go by car since every major compagny
or seals rep. is within a couple of hours.
Some examples from where I live to:
-Rotterdam 30 min.
-Amsterdam 1 hrs
-Antwerp 30 min
-Brussels 1 hrs
-Ruhr area 1 hrs to 1.5 hrs
-Luxembourg 3 hrs
-Hamburg 3.5 hrs
-Paris 4 hrs
-London 5 hrs
-Stuttgart 5 hrs
-Munich 7 hrs
-Lyon 7 hrs
The same counts for the most of North Western Europe

So, I only need a plane for fun.
