Hello!
i think there is a problem in all FS2Crew-Versions (in my P3dv4.1)
When transition is reached, the co will say "transition".
I set the correct altimeter while climb or descend flight.
specialy in Boeing planes this is done while press one Button!
now the Problem: in Europe in these days is a verry low altimeter setting, 
when the correct altimeter is set, the co says "reach altitude .... " but in verry low pressure
this altitude is never reachable that the co can say "now", while when correct altitude is set,
the plane has faster reached these altitude, then the co has says.

sorry, bad english, hope you can understand, what i will say.
hope you can correct this.

We'll look at it, but remember this is flight simulation.  We do our best to do this as realistically as possible, but it's impossible to deal with every conceivable scenario such as the one you described.

Best,
