Cold Weather Adjustments MET

Although for the Met exam you will be required use temperatures and ISAISA —International Standard Atmosphere deviations to convert indicated to true altitudes (and vice versa) in an actual aircraft on the approach you will not have time for this and so they keep it simple; if the temperature is too low (and therefore you are closer to the ground than your altimeter shows) then you apply a published cold weather increment to the published minima. Simply add this adjustment onto the minima, and fly to this new figure. The only mistake that can really be made is subtracting rather than adding.
