Quick question on altimetry errors
Just a quick question on altimetry errors: am I right in assuming that in the case of high pressure and low temperatures below ISA, the pressure error affects the altimeter more than the temperature error does?

A 1 C temperature deviation from ISA changes density altitude by 120ft, a 1 hPa pressure deviation changes it by 30ft. Since they don't have the same units (comparing apples to oranges), as Alex says: it depends.
