If your
altimeter setting is not set to "local", his computer radar will
misinterpret the altitude ModeC information from your aircraft.


The controller has no way of reading your altimeter, no matter what setting
you have in it. The only thing he can read is the mode C of your
transponder. That is always set to 29.92.
