INDEX INFLUENCE
Index influence is the variation of index when a body is loaded or
unloaded from the aircraft. It is usually referred in index units per
kilogram for variable weight bodies (cargo, catering, etc.), index units
per passenger when computing passenger influence or index units for
fixed weight bodies (flight attendant, cockpit observer, etc.).
