I guess your talking about adjusting the altimeter for local pressure.
When you fly for a long flight - more than a 100 miles the weather will change and I guess there times that even in short flights through weather systems the pressure could change enough to make a big enough difference that would cause ATC to alert you to up-date the altimeter. In Europe, when you fly above the transition level you set standard pressure - 29.92 inHG / 1013 hPa. Below this level or in the U.S. below FL180 you set local station pressure.
Every 28 feet = 1 hPa 8-)
If you adjust the altimeter and now the new reading is 100 feet different you need to turn off altitude hold, adjust the altitude up or down as needed using the pitch knob ( I know it's sensitive ) and when at the proper level re-engage altitude hold.
I hope that helps, if not
pour yourself a nice Grand Marnier
and just do a little "Free Flight" Bernardo
