I guess they use meters QFE, not QNH - will they give me a QNH alt. setting on request?
they use QFE but they can give you QNH if you ask for
What's transition level - on the charts it says "by ATC"?
Is on the ATIS alt. setting in MM or hPa?
TL (FL180

) TL is variable
as far as i remember QFE is only broadtcasted on ATIS
Do the controllers give vectors to intercept ILS's or do you have to fly full arrival and someone told me, to report all turns and alt. changes??!!
they usually do . be careful when descending below TL
calculate QNH from QFE well before and compare it to the one given by atc you can then keep your descend on QNH not a big deal.
on the back of some jeppesen enroute charts you have the meter to feets and feets to meter conversion table
sometimes on departure they don't want you to follow SID's...you keep rwy heading and contact 127.7 after TO.
Are the controllers hard to understand?
they are really....
Be safe
