Here's one of my peeves of the sim.
After reaching cruise altitude, ATC will contact me and tell me that I need to expidite my climb to whatever FL. Eventually my IFR gets cancelled and I swear at my computer. I know this problem is due to me not being able to set the altimeter to the correct setting. I constantly update it as ATC contacts me, but eventually, I lose whatever value it should be and frequently become a drifter. My quesion is, how do I keep my altimeter up to date? ATIS only works so far, and the ATC contact commands have their limits. This is starting to drive me insane!
