On the Classic 737 pressurisation panel, there are three altitudes that must be input prior to departure. One is the flight alt, which is obviously the altitude the route will be flown at. The second and third ones are the landing alt and the cabin alt. The cabin alt is the alt you are currently at, at the departure airfield, and the landing alt is the alt of the destination airport. However one of these figures are set -200 ft, but I'd like to know which one, and why?
Thanks.
If I've made any other mistakes please point them out.
