I continously get ALTITUDE BUST messages even if I am spot on the issued altitude. I keep refreshing the QNH using B-key. Is there a conflict between FS9 ad RC or am I doing something wrong? /Lars

if you are flying outside the united states, you have to deal with transition levels and transition altitudes. pressing the "B" key is not going to work for you.when you are told to climb or descend to a FL, your altimeter should be 29.92 or 1013.2 (i think)if you are told to climb or descend to nnnnn ft, then your altimeter should be at the local pressuredon't use the b key. dial the altimeter to the local pressure when you should be at a certain number of feet. dial the altimeter to 29.92/1013.2 when you are supposed to be at a certain flight levelthis is covered in the manual. read that section if it is still unclearjd

Thanks JDA more thorough reading of the manual then...!Rgds Lars
