QFE<\/strong> : refer to the height (vertical distance) above ground level (with no relation to mean sea level)<\/p>\n

QNH<\/strong> : Altitude – refer to the height (vertical distance) above mean sea level<\/p>\n

QNE<\/strong> : Pressure Height = Flight level – refer to the height (vertical distance) above 1013 (ISA) datum.<\/p>\n

QFF<\/strong> : is the pressure level at detecting point (usually airport weather office) reduce to MSL, it considers the actual environment condition and calculation applied.<\/p>\n
