Kollsman window can be selected up to 31 inches or 1050 hpa, so in this such a high pressure enviroment PA would be -1.000 when airfield elevation is 80 feet or below.
TO and LDG charts donīt show PA below -1.000. Is this really a limitation? or just manufactures do not perform flight test certification in these conditions.
There are few airfields in California below SL (e.g. Furnace Creek apt -210ī) not to mention Bar Yehuda Masada in Israel where elevation is -1266ī,in this aerodrome PA is below -1000 if QNH is above 1004 hpa.
Anyone has ever To/Ldg in these areas?
Any answer will be appreciated....
